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 :)

I get this error message using the command create:tram

Thanks EdT

Yep, caused by Z-up. I'll see what I can do.

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.

Thanks EdT

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

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.

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)

Hi Neo,

Having problems converting DAEs to trams. I put all the files in a zip and included a ReadMe with the description of the errors. http://edt.oni2.net/temp/NeoTRAM.zip

I was trying to make new animations, whenever you have time, please take a look. Thanks EdT

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:

System.TypeInitializationException: An exception was thrown by the type initializer for System.Drawing.GDIPlus --->  System.DllNotFoundException: gdiplus.dll

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
