:Hi Neo,

:We ([[User:Geyser|geyser]] and [[User:Admin|Alloc]]) are positively impressed by your recent contributions to the "OBD" knowledge database. Wow.
 
:What kind of activity (professional, Oni-related) has led you to such expertise? What tools do you use to analyse Oni?
Hi Neo, In the latest oni split 0.9.55, there seems to be a problem with converting ONCC files,
:[[OBD:OUP|OUP]] could use some expert OBD knowledge right now: we'd like to produce a fully functional release Soon(TM).
It fails to convert ONCC.xml files made by earlier to oni files .. says something about jump fields, the ONCC xml created by older versions are different from the ones created by this one, different fields <Jump Constants> and <Air Constants> instead of <Physics>, that would be ok we could switch to the new layout. However onisplit v.55 also fails to convert ONCC.xml it created back to oni. .. convert any ONCC.oni to xml, try to convert that xml back to oni, it fails.
:Would you consider private dialogue with us (mail, ICQ)? (about [[OBD:TXMP|TXMP]] and recurrent data types)
 
::[[User:Geyser|geyser]] 03:09, 6 March 2007 (CET)
2- It is also unable to convert a TRAM.oni file made from a dae by older versions back to xml : Operation is not valid due to current state of object. (containing QKEYS) while 0.941 is able to convert them.

Hi Neo, a bug has been ecountered by me in OniSplit's xml export. The bug applies on versions 0.9.50.0 and 0.9.52.0. If exported TRAM file has direct animation links, only the second direct link is written into XML file. The first direct link is ignored (is always an empty element).
 
This is an excerpt from KONCOMcomb_p_p XML file as created by OniSplit 0.9.52.0:
        <DirectAnimations>
            <Link />
            <Link>TRAMKONCOMcomb_p_p_k</Link>
        </DirectAnimations>
 
It should be:
        <DirectAnimations>
            <Link>TRAMKONCOMcomb_p_p_p</Link>
            <Link>TRAMKONCOMcomb_p_p_k</Link>
        </DirectAnimations>
 
Binary (*.oni) files contain both direct links. Exported XML files don't. Since usually only the first direct link is used, this bug poses quite a nuisance. Thank you in advance.
 
: It might be that the binary (oni/exe) are corrupted. My version of TRAMKONCOMcomb_p_p.oni was correctly extracted with onisplit 52. --[[User:Paradox-01|paradox-01]] 19:00, 8 July 2011 (CEST)
 
While I'm here I will take the chance to also ask something. I'm trying to create a combo. The animations work fine with animation type Kick, Kick2, Kick3 but not with KickRight, KrKr*, KrKrKr**. Could it be that those* animation types are dead? I hope you will find out what's wrong. --[[User:Paradox-01|paradox-01]] 19:00, 8 July 2011 (CEST)
 
: Loser: The problem more than likely was the fact that the TRAMKONCOMcomb_p_p_p.oni was not in the same directory as  TRAMKONCOMcomb_p_p.  To test, I removed TRAMKONCOMcomb_p_p_p.oni and got the same result as you did, added it back and got the correct output.  OniSplit wants all the files to be in the same directory.  [[User:EdT|EdT]] 23:36, 8 July 2011 (CEST)


:Hi guys,
:What's so much to be impressed, I just added some matrices here and there (mostly) ! :)
:I've been digging through Oni binary files for some time now (I think it was the summer of 2002 when I opened a dat file in a hex editor out of curiosity and when I saw all this TXMP, PNTA, IDXA, M3GM etc. stuff I thought that maybe I can get something out of this binary format). While I'm not a game developer I have a bit of a passion for 3D stuff so I learned a bit of Open GL and a bit more of Direct 3D so I'm quite familiar with transforms, quaternions, textures etc.
:As for used tools: much like anyone else I think. A hex editor, Excel for some things, SQL Server (database) for some others, Visual Studio (while it's file hex editor is quite dull it has a cool memory view in debug mode (you can set the number of displayed columns and the data type to display (integer/float, decimal/hexadecimal, 1/2/4 bytes). Obviously since this was in debug mode I had a program that loaded the DAT file into memory and where I could select a "file" (for various reasons I happened to call them "resources"). In addition I sometimes used a disasembler (home made, don't ask what it is) to stare at some things inside the executable :). Last but not least I have a "viewer" for a bunch of things from Oni (texures, 3D models, animations, environment). Good to test things like what I added to OBAN and OBOA file formats.
:As for mail/messenger (MSN or Yahoo) I guess it's OK but I don't feel like posting my mail address in here, it's a public place... any ideas ?
:;Neo
:OK, we won't ask you about your home-made disassembler ^^, but the ''viewer'' definitely sounds nice.
:Viewers (and exporters/importers) for things other than TXMP is what [[OBD:OUP|OUP]] currently lacks.
:Needless to say, we'd like to see those (is it C/C++?) and with any luck integrate them with OUP... ^^
:As for contact, ''our'' coordinates are available (just click our sigs). My YIM alias is '''serguei_mechkov'''.
::[[User:Geyser|geyser]] 02:53, 7 March 2007 (CET)
:I only have a few more doubts about the TXMP format. Will experiment a little tomorrow night.
::[[User:Geyser|geyser]] 02:53, 7 March 2007 (CET)
:Your homemade tools remind me of someone from the previous {{OCF}}... Have we met? ^^
::[[User:Geyser|geyser]] 02:53, 7 March 2007 (CET)


:Nope, we had not met before. As for viewer I intend to make it available but not right now, I kept doing experiments with it for the last 2 weeks or so and the whole source looks like after a war. The current one is written in C#, I also have one that is written in C++ but it has not been updated in a while so it lacks/gets wrong some things. I'll add you to my YIM list and you can ask for more details there, I'm not familiar with this wiki stuff to write too much... :) [[User:Neo|Neo]]

I've tried to run your Onibrowser several times, but I've failed. The test system is a laptop with WinXp + SP2, .NET 2.0 and XNA 1.0. When I doubleclick on the exe the harddisk makes only some noise for some seconds. That's it. Nothing else happens. No error message, no window. Nothing. Any idea what's wrong?


Can you add some code to the vtuneapi.dll that draws the trigger volumes (volume color: red, opacity: 10%)?
Neo, do you think we can have something like a -nodeps argument added to OniSplit? We could use a way to prevent the program from automatically following all dependencies when exporting files like ONCCs to XML. --[[User:Iritscen|Iritscen]] 14:26, 6 July 2011 (CEST)

Pathfinding issue fixed, though it seems to be still slightly off:

There is still the issue of falling through the ground.

Hi Neo,
 
I was able to create the pathfinding grids, however, they are offset from the geometry. Also, there is a spot where you will fall through the ground.
 
[[Image:junkyard.png]]
 
The bnv itself is correct:

Here are my files: http://edt.oni2.net/testlevel/TestLevel.zip
 
EDIT: Tested OniSplit with the arena level data: <nowiki>http://mods.oni2.net/system/files/80200ArenaofHurt.zip</nowiki>
Extracted the AKEV, then used create:akev to import the level.  The pathfinding grids were offset from the geometry and there were areas where the player will fall through the floor.

Hi Neo,
I have tried Your ".dae" to ".xml" animation importer. I keep getting message ".dae files cannot be imported as TRAM". Can you tell me please where is the problem? Thank you. --[[User:Loser|Loser]] 13:00, 11 July 2010 (UTC)
 
Hello, to import an animation you need an xml file and a dae file. If you try to export a TRAM to xml you get both files and when importing you need to provide the xml file, not the dae file. The dae file is referenced from inside the xml file (see the DaeImport element) [[User:Neo|Neo]]
 
 
New OniSplit version: OniSplit v0.9.52 (<nowiki>https://cid-639aa31296681bfe.skydrive.live.com/self.aspx/Oni/OniSplit/OniSplit%5E_v0.9.52.zip</nowiki>, dead link)
 
What's new:
:* When a TRBS file is exported to xml the geometry is exported to separate .dae files, one .dae file for each LOD
:* New -anim-body option. This allows a particular body (ONCC or TRBS) to be specified when exporting animations:
 
  onisplit -extract:xml out -anim-body:ONCCbarabus.oni TRAMsomething.oni
 
:* New -recurse option for the xml exporter. Have fun :)


[[User:Ssg|Ssg]] 12:40, 22 December 2007 (CET)
  onisplit -extract:xml out -recurse ONCCbarabus.oni
1. Hmm, that's unusual. Things to check:
- make sure you run it from the local disk and not from a network share
- make sure you have the correct xna version installed. The latest OniBrowser uses this
[[http://www.microsoft.com/downloads/details.aspx?FamilyID=a7da4763-6807-4bd5-8d18-18c60c437f93&DisplayLang=en|XNA Framework 1.0 Refresh]]. Previously there was another 1.0 version (without Refresh in title) but that was removed from download.
- update DirectX


If nothing works take a look in the event viewer, maybe there is something about failing to start (go to Control Panel, Administrative Tools, Event Viewer, Application Log).  
:* Changed light color in the environment importer to white (it used to be blueish)
:* New -env-notxmp option. This prevents the automatic creation of TXMP files while importing the environment.
:* Made -normals work when importing TRBS from xml + dae files.


2. I suppose it is possible but I'm not sure what it takes. Besides, I already did this for OniBrowser so I'll try to post a new version of OniBrowser one of these days.
New OniSplit version: OniSplit v0.9.41
 
What's new:
 
:* fixed the Collada importer to work with 3DSMax exported files
 
New OniSplit version: OniSplit v0.9.40
 
What's new:
 
:* support for exporting/importing [[OBD:BINA/SABD|sound animations]] to/from xml files
:* better Collada export for environment
:* support for full color transparent textures (-format:bgra32 on the command line, ARGB8888 format in an xml file)
:* different (hopefully better) xml export format for animations (this one is actually from 0.9.38 but since that wasn't mentioned here...)
:* a more or less complete animation importer. This one deservers some notes:
::-unlike other importers that produce .oni files this one produces and .xml file (similar to the one you get when exporting a TRAM)
::when you do
  onisplit -create:tram target_dir animation.dae
::in the target dir you'll get a TRAManimation.xml file.
::You need to add some stuff to that file to make it actually work as an animation. In particular the animation type, from/to states and varient needs to be set.
::-For all I know this works with animations exported from Oni and modified in Softimage. If you come up with a completly new animation it should work as long as the skeleton is similar to the one used in Oni.
::-Note that the geometry that is present inside the Collada file is used to compute the "vertical extents" so it better be the same or close to the one the animation is intended for.
::-The biggest problem are the attacks. While it's not difficult to add attacks to the xml file, computing the necessary "extents" is not going to be easy. I guess in the end I'll have to add some command to OniSplit to do it.
::-Everything else that I forgot :)

Does not work. I've installed XNA 2.0 but nothing happened. Again no error message and no window. The strange thing is that the "old" version of OniBrowser doesn't work with XNA 2.0 too. It needs XNA 1.0. So any ideas what's wrong with the current OniBrowser version?
Hi Neo,
 
When you have time, can you take a look at this:

When I use the latest FBX Converter 2010.2 to convert FBX to DAE, I get this problem. However, when I use an older version, it works fine. Here are the DAEs from both version: http://edt.oni2.net/temp/TRBSproblem.zip G2 is uses the new version, G1 uses the old.

Oops... I forgot a file. Please [http://cid-639aa31296681bfe.skydrive.live.com/self.aspx/Oni/OniBrowser.zip redownload]
Oh boy, the new converter uses matrix transforms instead of individual scale/rotate/translate transforms. I'll see what I can do...


[[User:Neo|Neo]]
[[User:Neo|Neo]]


Doesn't work either. Same result as above. The "old" version has a XPtheme.dll. Maybe that's the problem? (I've copied it to the folder with the current version but no success.)

The Iron Demon walks! Sorta...


I'm out of ideas. The last zip missed Oni.Files.dll so check if you got it now. XPTheme.dll is old, not needed anymore. Try to take a look in the event viewer for an error about Oni.Browser.exe.
You can see the video here: http://edt.oni2.net/ID/IDwalk.wmv

I converted the files from Bobbysoon (TRAMID_run1stepb.DAE, TRAMID_runstart.DAE, TRAMID_runstop.DAE) to xml.  The XML gave the pelvis height as <Height>-2175.5</Height>, so I removed the negative and divided the height by 100.  But as you can see, the model floats above the ground.  Also, the velocity has some large numbers in the first part <Velocity>-4.076141 0</Velocity> I think that is the cause of the ID moving sideways not forward.

Hmm... I just discovered that I can't export TXMPs from a .dat file to the PNG format. I am attempting to use the -extract:png command on a virgin .dat file. The -extract:tga options works fine, but the -extract:png option gives:

:TGA always works because it's all done in OniSplit. For PNG/JPG I'm using the framework (.NET/Mono) and Mono seems to have a problem. [[User:Neo|Neo]]

::Okay, after many aborted attempts at updating mono (I was running 2.0.1) by building from source or using their binary installer, I realized that the installer was putting the files in some meaningless directory, and I ended up copying them to the right system directories, hoping I didn't overwrite libraries that were supposed to stay unchanged. Who knows what the consequences will be down the road for other stuff, but OniSplit now exports PNGs properly for me! --[[User:Iritscen|Iritscen]] 20:28, 3 January 2010 (UTC)

Observations of importing TRAMs to XSI.
 
Sometimes, imported TRAMs will have odd rotations mainly related to the pelvis and thighs.  Here is one example, the Striker's walking TRAM:
http://edt.oni2.net/TRAMS/WalkOS.wmv  As you can see the pelvis and thighs are rotating in an odd fashion.  This is due to euler vs quaternion rotations.  To see it correctly in XSI, you can use the option to "Convert Euler Rotation to Quaternion" on the pelvis and thighs, then the animation appears correct: http://edt.oni2.net/TRAMS/WalkQT.wmv  However, when importing a converted animation back to Oni, you get this result: http://edt.oni2.net/TRAMS/WalkOni.wmv
 
When a TRAM is imported to XSI, to "unwrap" a model from the default animation state, the right thigh is rotated 180 on the X axis and -180 on the Z axis, the left is rotated -180 on the X and -180 on the Z axis. Somehow, from this starting point, whenever XSI moves the thigh from a negative to a positive angle (or in the case of this example from positive to negative), the part would rotate the long way around as shown here: http://edt.oni2.net/TRAMS/ThighXZaxis.wmv
 
One workaround is to insert keyframes to cause the animation to rotate in the correct direction.


The event viewer gaves  me an error message: "Couldn't find Microsoft.VC80.CRT". I've googled a bit and it looks like a general problem for Vuisal C/C++ programs. So please search the net for "VC80.CRT" to solve this problem. (Microsoft MSDN help: http://msdn2.microsoft.com/en-us/library/ms235342(vs.80).aspx )
I found another approach that seems to work, if you are making an animation from scratch. That is to rotate the thighs down 180 on the Y axis. So far in my testing, there are no odd rotations: http://edt.oni2.net/TRAMS/ThighYaxis.wmv


I've installed the "Microsoft Visual C++ 2005 Redistributable Package (x86)" (http://www.microsoft.com/downloads/details.aspx?FamilyId=32BC1BEE-A3F9-4C13-9C99-220B62A191EE&displaylang=en ) but it didn't help.
The Striker DAE files and the XSI scene files are here: http://edt.oni2.net/TRAMS/TRAMfiles.zip


[[User:Ssg|Ssg]] 22:00, 3 January 2008 (CET)
[[User:EdT|EdT]]


Stupid me, I tend to forget that XNA is actually written in C++ and it needs that. Now the only problem is that you need the [http://www.microsoft.com/downloads/details.aspx?familyid=200B2FD9-AE1A-4A14-984D-389C36F85647&displaylang=en SP1 C++ redist]. You were close :) .
I'm still unsure how the XZ animation was produced. There's a keyframe (for the Z rotation of left_thigh) that causes this. It's value is 135 while all the other keyframes for Z are well below 0 (-150..-180). If you move that keyframe to something like -215 then the animation works fine. Or so it appears to me...  


[[User:Neo|Neo]]
[[User:Neo|Neo]]


Hooray. It works. Thank you. And yes, I was really close. It was a fifty-fifty chance and I chose the wrong. As usual. (Grrrr... Murphy... just you wait!)
:That's true about changing the keyframe to -215, however, for all the TRAMs exported from Oni, the number for the rotations are always less than 180 or -180. When the thigh is positioned in front of the body, the rotation on the Z axis is negative, between the range of -0.x to -179.x and when it is positioned behind the body, the rotation number is positive, between the range of 0.x to 179.x. So my XZ animation was reflecting that aspect. [[User:EdT|EdT]]
 
::Ah, I didn't think about that. I don't think it matters if those angles are between -180..180 or not, I haven't seen any problems while trying to import the animation with -215. [[User:Neo|Neo]]


I would like to take screenshots as in Oni (screenshot+number.bmp). Do you think you can add such a feature? And can you make your program run in real fullscreen?
:::Then my question is, would it be possible to program OniSplit one day, so that it can produce a TRAM DAE that will import into XSI without any of those odd rotations of the pelvis and thighs? Or for OniSplit to import a TRAM DAE that was converted from Euler to Quaternion rotation? It will be much easier to modify existing TRAMs without having to deal with those odd rotations.  Thanks [[User:EdT|EdT]]


[[User:Ssg|Ssg]] 02:27, 4 January 2008 (CET)
::::TRAM DAE: yes, I think so. I have an idea though I've yet to test it. Euler to Quaternion: I don't know why that doesn't work, I'll check. In theory there should be no problem. [[User:Neo|Neo]]
::::Found another solution (in XSI): use "Make rotation keys continuous" (in the same menu as Euler to Quaternion). [[User:Neo|Neo]]

            v.x = -Mathf.PI / 2;
            v.z = 0;
            return NormalizeAngles(v * Mathf.Rad2Deg);
        }
        Quaternion q = new Quaternion(q1.w, q1.z, q1.x, q1.y);
        v.y = (float)Math.Atan2(2f * q.x * q.w + 2f * q.y * q.z, 1 - 2f * (q.z * q.z + q.w * q.w));    // Yaw
        v.x = (float)Math.Asin(2f * (q.x * q.z - q.w * q.y));                            // Pitch
        v.z = (float)Math.Atan2(2f * q.x * q.y + 2f * q.z * q.w, 1 - 2f * (q.y * q.y + q.z * q.z));      // Roll
        return NormalizeAngles(v * Mathf.Rad2Deg);
    }
p.s. sorry, not found any code tags or something like that.
p.s.s. Mathf.Rad2Deg must be 57.2958f. other Mathf stuff is similar to Math
p.s.s.s anyway, looks like the root of evil is not in quaternion -> euler conversion. i will try to investigate that.

Is there a way to switch the visibility of the flags/sounds/tvs on/off in general and separate?

Hi Neo,


oh, a new version - gonna check it out
I have thought of adding a point to your todo list if you don't mind. Since the throw target is sort of reversed played in Oni (body rotated by 180 degrees, reversed movement, if I remember correctly), it would come handy if Onisplit can reverse it. Doing it in XSI would be a load of unnecessary work each time. Onisplit could easily recognize this special animation in the XML tags (<Flag>... ThrowTarget ...</Flag>). --[[User:Paradox-01|Paradox-01]] 15:21, 29 March 2010 (UTC)

Here's a mystery [which has been solved, see edits below this one]: what is wrong with Oni's sound occlusion with 44Khz sounds in Windows (and possibly all occlusion on Macs)? Here are two alternate versions of a package: <nowiki>http://iritscen.oni2.net/temp/06000MissingSoundsNoOcc.zip</nowiki> (dead link) and <nowiki>http://iritscen.oni2.net/temp/06000MissingSoundsOcc.zip</nowiki> (dead link). This package simply adds a sound to the gears at the end of Science Prison. There are probably any number of ways to test for this issue, but this is how I noticed the problem, so I can vouch for its reproducibility.
# Install the Occ version of the package. This uses 22Khz sound.
# Load Science Prison SP1 so there's no music or enemies around, and do "chr_location 0 676.3 64.7 -1898.3". You're now on top of the gears.
# Run into one of the nearby rooms with windows. The sound comes from the point you teleported to, so position yourself so the "ray" from the sound can reach you through a window. If you are standing with part of the room's wall in the way, the sound may cut out completely, which you don't want.
# Listen to the sound. Isn't it soothing? Now shoot the glass out (the M. Bow is a nice choice, it's quiet so you can hear the gears more clearly). The sound should get louder. You can hear this in my movie <nowiki>http://iritscen.oni2.net/temp/GearsTestWindows.mp4</nowiki> (dead link) (though the gears sound was distorted at the time because I didn't set the .grp properly, that's besides the point in this case).
# Now replace the Occ package with the NoOcc package and install it. This one uses 44Khz sound.
# Performing the same test, you should hear the gears at the same volume through glass as without the glass in the way. You can hear this issue in my movie <nowiki>http://iritscen.oni2.net/temp/GearsTestMac.mp4</nowiki> (dead link). Obviously in the Mac test I was using 22Khz sound, and yet I experienced the same issue. I suspect something was changed in the occlusion code between the Windows and Mac releases, perhaps in tandem with the removal of 44Khz sound support, that glommed the Windows 44Khz bug onto the Mac 22Khz sound code.


*screenshots - I think I can add such a thing but isn't pressing Print Screen key enough?
Now, is it definitely a problem with Oni? I guess it is if we're sure that the sounds and .grp I provided are formatted and imported correctly. Or perhaps I'm totally mixed up here and don't know what I'm talking about. I've never done sound work before in Oni. --[[User:Iritscen|Iritscen]] ([[User talk:Iritscen|talk]]) 15:36, 25 April 2013 (CEST)

*flag/sounds/tvs visibility - not yet, wanting to do it this weekend


[[User:Neo|Neo]]
: Iritscen: Try your test again with the command sound_show_debug=1 you will see a list of sounds and the sound level for each one.  When you are in front of the gears the level is 1 for gears, gears.aif .  Then move into one of the rooms behind the glass, the sound level will drop to around .6 or .7 depending on how far away you are.  Shoot out the glass and then the sound level will return to 1.[[User:EdT|EdT]] ([[User talk:EdT|talk]]) 17:02, 25 April 2013 (CEST)


*screenshots: I would like to create an overview of all TVs. It's not very handy to do that with the Print Screen key. That's why I've asked for a screenshot-shortcut.
::D'oh. I was wondering if I should have put this on Paradox's page but I felt that it was probably an Oni bug and I shouldn't distract 'dox anymore. I guess you would have had a simple solution to the problem no matter where I put it, EdT. So here's what happened: the NoOcc package has a custom .grp so that I can specify "2" channels, AKA 44Khz sound, since Oni's .grp expects 22Khz. What I had forgotten that I also tried to turn up the volume of the gears noise by setting the .grp's Volume to 2 instead of 1. Because a sound's maximum actual volume in Oni is 1, what happens with a >1 volume setting is that a sound will reach 100% volume from farther away than if the sound was set to a volume of 1. Because I was standing within the >1 apparent volume range of the NoOcc package's louder gears, I couldn't hear any difference in sound volume when a window got in the way. That's because the volume was still greater than 1 even though the sound was in fact being occluded from say, 1.9 to 1.4.
::Well, I learned something about sound today! Sorry for cluttering your talk page unnecessarily, Neo (I know you won't be seeing this until the weekend anyway). The funny thing is that I just got done telling someone on the forum about sound_show_debug, but I had no idea that the numbers in the left column were apparent volume so I didn't think of using the debug display on my package. Well, thanks EdT, at least I know everything is working properly. --[[User:Iritscen|Iritscen]] ([[User talk:Iritscen|talk]]) 18:06, 25 April 2013 (CEST)

Talk page archives: #1 - #2 - #3 - #4 - #5

Hi Neo, In the latest oni split 0.9.55, there seems to be a problem with converting ONCC files, It fails to convert ONCC.xml files made by earlier to oni files .. says something about jump fields, the ONCC xml created by older versions are different from the ones created by this one, different fields <Jump Constants> and <Air Constants> instead of <Physics>, that would be ok we could switch to the new layout. However onisplit v.55 also fails to convert ONCC.xml it created back to oni. .. convert any ONCC.oni to xml, try to convert that xml back to oni, it fails.

2- It is also unable to convert a TRAM.oni file made from a dae by older versions back to xml : Operation is not valid due to current state of object. (containing QKEYS) while 0.941 is able to convert them.

reported by Samer on July 10 2011


Hi Neo, a bug has been ecountered by me in OniSplit's xml export. The bug applies on versions 0.9.50.0 and 0.9.52.0. If exported TRAM file has direct animation links, only the second direct link is written into XML file. The first direct link is ignored (is always an empty element).

This is an excerpt from KONCOMcomb_p_p XML file as created by OniSplit 0.9.52.0:

       <DirectAnimations>
           <Link />
           <Link>TRAMKONCOMcomb_p_p_k</Link>
       </DirectAnimations>

It should be:

       <DirectAnimations>
           <Link>TRAMKONCOMcomb_p_p_p</Link>
           <Link>TRAMKONCOMcomb_p_p_k</Link>
       </DirectAnimations>

Binary (*.oni) files contain both direct links. Exported XML files don't. Since usually only the first direct link is used, this bug poses quite a nuisance. Thank you in advance.

It might be that the binary (oni/exe) are corrupted. My version of TRAMKONCOMcomb_p_p.oni was correctly extracted with onisplit 52. --paradox-01 19:00, 8 July 2011 (CEST)

While I'm here I will take the chance to also ask something. I'm trying to create a combo. The animations work fine with animation type Kick, Kick2, Kick3 but not with KickRight, KrKr*, KrKrKr**. Could it be that those* animation types are dead? I hope you will find out what's wrong. --paradox-01 19:00, 8 July 2011 (CEST)

Loser: The problem more than likely was the fact that the TRAMKONCOMcomb_p_p_p.oni was not in the same directory as TRAMKONCOMcomb_p_p. To test, I removed TRAMKONCOMcomb_p_p_p.oni and got the same result as you did, added it back and got the correct output. OniSplit wants all the files to be in the same directory. EdT 23:36, 8 July 2011 (CEST)




Neo, do you think we can have something like a -nodeps argument added to OniSplit? We could use a way to prevent the program from automatically following all dependencies when exporting files like ONCCs to XML. --Iritscen 14:26, 6 July 2011 (CEST)

Oops, never mind, it sounds like this is already OniSplit's default behavior.... --Iritscen 16:24, 6 July 2011 (CEST)

Pathfinding issue fixed, though it seems to be still slightly off:

There is still the issue of falling through the ground.

Hi Neo,

I was able to create the pathfinding grids, however, they are offset from the geometry. Also, there is a spot where you will fall through the ground.

The bnv itself is correct:

EDIT: Tested OniSplit with the arena level data: http://mods.oni2.net/system/files/80200ArenaofHurt.zip Extracted the AKEV, then used create:akev to import the level. The pathfinding grids were offset from the geometry and there were areas where the player will fall through the floor.

Hi Neo, I have tried Your ".dae" to ".xml" animation importer. I keep getting message ".dae files cannot be imported as TRAM". Can you tell me please where is the problem? Thank you. --Loser 13:00, 11 July 2010 (UTC)

Hello, to import an animation you need an xml file and a dae file. If you try to export a TRAM to xml you get both files and when importing you need to provide the xml file, not the dae file. The dae file is referenced from inside the xml file (see the DaeImport element) Neo


New OniSplit version: OniSplit v0.9.52 (https://cid-639aa31296681bfe.skydrive.live.com/self.aspx/Oni/OniSplit/OniSplit%5E_v0.9.52.zip, dead link)

What's new:

  • When a TRBS file is exported to xml the geometry is exported to separate .dae files, one .dae file for each LOD
  • New -anim-body option. This allows a particular body (ONCC or TRBS) to be specified when exporting animations:
  onisplit -extract:xml out -anim-body:ONCCbarabus.oni TRAMsomething.oni
  • New -recurse option for the xml exporter. Have fun :)
  onisplit -extract:xml out -recurse ONCCbarabus.oni
  • Changed light color in the environment importer to white (it used to be blueish)
  • New -env-notxmp option. This prevents the automatic creation of TXMP files while importing the environment.
  • Made -normals work when importing TRBS from xml + dae files.

New OniSplit version: OniSplit v0.9.41

What's new:

  • fixed the Collada importer to work with 3DSMax exported files

New OniSplit version: OniSplit v0.9.40

What's new:

  • support for exporting/importing sound animations to/from xml files
  • better Collada export for environment
  • support for full color transparent textures (-format:bgra32 on the command line, ARGB8888 format in an xml file)
  • different (hopefully better) xml export format for animations (this one is actually from 0.9.38 but since that wasn't mentioned here...)
  • a more or less complete animation importer. This one deservers some notes:
-unlike other importers that produce .oni files this one produces and .xml file (similar to the one you get when exporting a TRAM)
when you do
 onisplit -create:tram target_dir animation.dae
in the target dir you'll get a TRAManimation.xml file.
You need to add some stuff to that file to make it actually work as an animation. In particular the animation type, from/to states and varient needs to be set.
-For all I know this works with animations exported from Oni and modified in Softimage. If you come up with a completly new animation it should work as long as the skeleton is similar to the one used in Oni.
-Note that the geometry that is present inside the Collada file is used to compute the "vertical extents" so it better be the same or close to the one the animation is intended for.
-The biggest problem are the attacks. While it's not difficult to add attacks to the xml file, computing the necessary "extents" is not going to be easy. I guess in the end I'll have to add some command to OniSplit to do it.
-Everything else that I forgot :)

Neo

New OniSplit version: OniSplit v0.9.37

What's new:

  • support for transparency in the environment importer


New OniSplit version: OniSplit v0.9.35

What's new:

  • conversion of recorded films (.dat binary files) to xml files that can be used to create FILM .oni files
   OniSplit film2xml out_dir film.dat

Hi Neo,

When you have time, can you take a look at this:

TRBSproblem.jpg

When I use the latest FBX Converter 2010.2 to convert FBX to DAE, I get this problem. However, when I use an older version, it works fine. Here are the DAEs from both version: http://edt.oni2.net/temp/TRBSproblem.zip G2 is uses the new version, G1 uses the old.

Thanks EdT

Oh boy, the new converter uses matrix transforms instead of individual scale/rotate/translate transforms. I'll see what I can do...

Neo



The Iron Demon walks! Sorta...

You can see the video here: http://edt.oni2.net/ID/IDwalk.wmv

I converted the files from Bobbysoon (TRAMID_run1stepb.DAE, TRAMID_runstart.DAE, TRAMID_runstop.DAE) to xml. The XML gave the pelvis height as <Height>-2175.5</Height>, so I removed the negative and divided the height by 100. But as you can see, the model floats above the ground. Also, the velocity has some large numbers in the first part <Velocity>-4.076141 0</Velocity> I think that is the cause of the ID moving sideways not forward.

Files here: http://edt.oni2.net/ID/ID_Files.zip

Ha ha, that's going in my album of weird modding results. Anyway, I didn't even realize that animations were supposed to work yet, I thought we were waiting for an update to OniSplit. --Iritscen 14:33, 29 November 2009 (UTC)

This occurred in both 0.9.38 and 0.9.41 on my Mac. I used to always extract TXMPs as TGA, so I don't know when this actually worked for me. --Iritscen 17:54, 2 January 2010 (UTC)

TGA always works because it's all done in OniSplit. For PNG/JPG I'm using the framework (.NET/Mono) and Mono seems to have a problem. Neo
I just tested it myself and I was able to extract all the textures from a virgin .dat file as PNG. I'm using the latest version 0.9.45 and the latest Mono framework. OSX 10.5.8 and 10.6.2 EdT
Okay, after many aborted attempts at updating mono (I was running 2.0.1) by building from source or using their binary installer, I realized that the installer was putting the files in some meaningless directory, and I ended up copying them to the right system directories, hoping I didn't overwrite libraries that were supposed to stay unchanged. Who knows what the consequences will be down the road for other stuff, but OniSplit now exports PNGs properly for me! --Iritscen 20:28, 3 January 2010 (UTC)

Observations of importing TRAMs to XSI.

Sometimes, imported TRAMs will have odd rotations mainly related to the pelvis and thighs. Here is one example, the Striker's walking TRAM: http://edt.oni2.net/TRAMS/WalkOS.wmv As you can see the pelvis and thighs are rotating in an odd fashion. This is due to euler vs quaternion rotations. To see it correctly in XSI, you can use the option to "Convert Euler Rotation to Quaternion" on the pelvis and thighs, then the animation appears correct: http://edt.oni2.net/TRAMS/WalkQT.wmv However, when importing a converted animation back to Oni, you get this result: http://edt.oni2.net/TRAMS/WalkOni.wmv

When a TRAM is imported to XSI, to "unwrap" a model from the default animation state, the right thigh is rotated 180 on the X axis and -180 on the Z axis, the left is rotated -180 on the X and -180 on the Z axis. Somehow, from this starting point, whenever XSI moves the thigh from a negative to a positive angle (or in the case of this example from positive to negative), the part would rotate the long way around as shown here: http://edt.oni2.net/TRAMS/ThighXZaxis.wmv

One workaround is to insert keyframes to cause the animation to rotate in the correct direction.

I found another approach that seems to work, if you are making an animation from scratch. That is to rotate the thighs down 180 on the Y axis. So far in my testing, there are no odd rotations: http://edt.oni2.net/TRAMS/ThighYaxis.wmv

The Striker DAE files and the XSI scene files are here: http://edt.oni2.net/TRAMS/TRAMfiles.zip

EdT

I'm still unsure how the XZ animation was produced. There's a keyframe (for the Z rotation of left_thigh) that causes this. It's value is 135 while all the other keyframes for Z are well below 0 (-150..-180). If you move that keyframe to something like -215 then the animation works fine. Or so it appears to me...

Neo

That's true about changing the keyframe to -215, however, for all the TRAMs exported from Oni, the number for the rotations are always less than 180 or -180. When the thigh is positioned in front of the body, the rotation on the Z axis is negative, between the range of -0.x to -179.x and when it is positioned behind the body, the rotation number is positive, between the range of 0.x to 179.x. So my XZ animation was reflecting that aspect. EdT
Ah, I didn't think about that. I don't think it matters if those angles are between -180..180 or not, I haven't seen any problems while trying to import the animation with -215. Neo
Then my question is, would it be possible to program OniSplit one day, so that it can produce a TRAM DAE that will import into XSI without any of those odd rotations of the pelvis and thighs? Or for OniSplit to import a TRAM DAE that was converted from Euler to Quaternion rotation? It will be much easier to modify existing TRAMs without having to deal with those odd rotations. Thanks EdT
TRAM DAE: yes, I think so. I have an idea though I've yet to test it. Euler to Quaternion: I don't know why that doesn't work, I'll check. In theory there should be no problem. Neo
Found another solution (in XSI): use "Make rotation keys continuous" (in the same menu as Euler to Quaternion). Neo
I tested the it, however, TRAMs converted that way do not appear correctly in Oni: http://edt.oni2.net/TRAMS/WalkRot.wmv files:http://edt.oni2.net/TRAMS/TRAMfiles2.zip EdT
Not to say that this is the only problem but... you're .dae files for left and right are identical :) Neo
"The Make rotation keys continuous"is working great, no problems. Except for the stupid user error with the Striker's walk... lol EdT
Googled a possible solution and fitted it to one method. I have already checked it for some quaternions, which should result in euler angles, which contains values greater than 180 degrees, and it works fine. Here it is:
   public static Vector3 FromQ2(Quaternion q1)
   {
       float sqw = q1.w * q1.w;
       float sqx = q1.x * q1.x;
       float sqy = q1.y * q1.y;

p.s. sorry, not found any code tags or something like that. p.s.s. Mathf.Rad2Deg must be 57.2958f. other Mathf stuff is similar to Math p.s.s.s anyway, looks like the root of evil is not in quaternion -> euler conversion. i will try to investigate that. 6opoDuJIo


Hi Neo,

I have thought of adding a point to your todo list if you don't mind. Since the throw target is sort of reversed played in Oni (body rotated by 180 degrees, reversed movement, if I remember correctly), it would come handy if Onisplit can reverse it. Doing it in XSI would be a load of unnecessary work each time. Onisplit could easily recognize this special animation in the XML tags (<Flag>... ThrowTarget ...</Flag>). --Paradox-01 15:21, 29 March 2010 (UTC)


Here's a mystery [which has been solved, see edits below this one]: what is wrong with Oni's sound occlusion with 44Khz sounds in Windows (and possibly all occlusion on Macs)? Here are two alternate versions of a package: http://iritscen.oni2.net/temp/06000MissingSoundsNoOcc.zip (dead link) and http://iritscen.oni2.net/temp/06000MissingSoundsOcc.zip (dead link). This package simply adds a sound to the gears at the end of Science Prison. There are probably any number of ways to test for this issue, but this is how I noticed the problem, so I can vouch for its reproducibility.

  1. Install the Occ version of the package. This uses 22Khz sound.
  2. Load Science Prison SP1 so there's no music or enemies around, and do "chr_location 0 676.3 64.7 -1898.3". You're now on top of the gears.
  3. Run into one of the nearby rooms with windows. The sound comes from the point you teleported to, so position yourself so the "ray" from the sound can reach you through a window. If you are standing with part of the room's wall in the way, the sound may cut out completely, which you don't want.
  4. Listen to the sound. Isn't it soothing? Now shoot the glass out (the M. Bow is a nice choice, it's quiet so you can hear the gears more clearly). The sound should get louder. You can hear this in my movie http://iritscen.oni2.net/temp/GearsTestWindows.mp4 (dead link) (though the gears sound was distorted at the time because I didn't set the .grp properly, that's besides the point in this case).
  5. Now replace the Occ package with the NoOcc package and install it. This one uses 44Khz sound.
  6. Performing the same test, you should hear the gears at the same volume through glass as without the glass in the way. You can hear this issue in my movie http://iritscen.oni2.net/temp/GearsTestMac.mp4 (dead link). Obviously in the Mac test I was using 22Khz sound, and yet I experienced the same issue. I suspect something was changed in the occlusion code between the Windows and Mac releases, perhaps in tandem with the removal of 44Khz sound support, that glommed the Windows 44Khz bug onto the Mac 22Khz sound code.

Now, is it definitely a problem with Oni? I guess it is if we're sure that the sounds and .grp I provided are formatted and imported correctly. Or perhaps I'm totally mixed up here and don't know what I'm talking about. I've never done sound work before in Oni. --Iritscen (talk) 15:36, 25 April 2013 (CEST)

Iritscen: Try your test again with the command sound_show_debug=1 you will see a list of sounds and the sound level for each one. When you are in front of the gears the level is 1 for gears, gears.aif . Then move into one of the rooms behind the glass, the sound level will drop to around .6 or .7 depending on how far away you are. Shoot out the glass and then the sound level will return to 1.EdT (talk) 17:02, 25 April 2013 (CEST)
D'oh. I was wondering if I should have put this on Paradox's page but I felt that it was probably an Oni bug and I shouldn't distract 'dox anymore. I guess you would have had a simple solution to the problem no matter where I put it, EdT. So here's what happened: the NoOcc package has a custom .grp so that I can specify "2" channels, AKA 44Khz sound, since Oni's .grp expects 22Khz. What I had forgotten that I also tried to turn up the volume of the gears noise by setting the .grp's Volume to 2 instead of 1. Because a sound's maximum actual volume in Oni is 1, what happens with a >1 volume setting is that a sound will reach 100% volume from farther away than if the sound was set to a volume of 1. Because I was standing within the >1 apparent volume range of the NoOcc package's louder gears, I couldn't hear any difference in sound volume when a window got in the way. That's because the volume was still greater than 1 even though the sound was in fact being occluded from say, 1.9 to 1.4.
Well, I learned something about sound today! Sorry for cluttering your talk page unnecessarily, Neo (I know you won't be seeing this until the weekend anyway). The funny thing is that I just got done telling someone on the forum about sound_show_debug, but I had no idea that the numbers in the left column were apparent volume so I didn't think of using the debug display on my package. Well, thanks EdT, at least I know everything is working properly. --Iritscen (talk) 18:06, 25 April 2013 (CEST)

Hi Neo,

I've tried a couple of OniSplit commands but I couldn't get some to work with latest public version (0.9.94.0). The commands are the follow:

Conversion of ONWC > OBJ and DAE:

  -extract:obj outputdir input_ONWC.oni
  -extract:dae outputdir input_ONWC.oni

both execute with sucess but don't generate output.

Conversion of OBJ > M3GM:

  -create:m3gm outputdir input.obj

I get the exception:

  System.ArgumentOutOfRangeException: O ¡ndice estava fora do intervalo. Tem de ser nÆo negativo e inferior ao tamanho da colec?Æo.
  Nome do par?metro: index
  em System.ThrowHelper.ThrowArgumentOutOfRangeException()
  em Oni.Dae.IO.ObjReader.ReadVertices(String[] tokens)
  em Oni.Dae.IO.ObjReader.ReadFace(String[] tokens)
  em Oni.Dae.IO.ObjReader.ReadObjFile(String filePath)
  em Oni.Dae.IO.ObjReader.ReadFile(String filePath)
  em Oni.Motoko.GeometryImporter.Import(String filePath, String outputDirPath)
  em Oni.Program.ExecuteTasks(String[] args, String outputDirPath, Set`1 importedFiles, Queue`1 taskQueue)
  em Oni.Program.CreateGeneric(String[] args)
  em Oni.Program.Main(String[] args)

Could these be fixed? Thanks. Script 10k (talk) 22:07, 3 January 2014 (CET)


Hi Neo, do you still stop by the wiki? Not sure if you will see this. I sent you an email at what I'm pretty sure is your Yahoo! address, but I don't know if you still check that email, and it doesn't seem that you use Yahoo! Messenger anymore. I'm trying to get back in touch with you to ask you some questions about OniSplit, etc. --Iritscen (talk) 00:02, 27 September 2016 (CEST)
