OBD talk:TRMA

Quoting geyser from Oni Central Forum:

"Oni characters have a modular design one can take advantage of, by "swapping bones" and authoring all-new textures.

One can thus create entities more or less closely related to Oni's original ones, possibly with new storyline roles.

(Ninja Comguys, BGI executives, cyborg enforcers, WCG troops... you name it: it's almost easy - if you're creative)"

I was hoping when you had time, you could explain how this is done.

My thoughts for a simple change might be done is to duplicate an existing ONCC and TRMA link the 2 together and in the TRMA change the TXMP's links. But can this be done with a hex editor or does it still require OUP?

Anyways, no rush, but I think having an example will be very useful for those who want to mod Oni.

Well I made some progress in adding another character to Oni. I duplicated ONCCk4_G.oni renamed it ONCCk4_H.oni, duplicated TRMATCTFswat_high_texture_generic2 renamed it TRMAk4_H_001_high_texture_generic.oni Fixed the link in the ONCC to point to TRMAk4_H_001_high_texture_generic.oni

Of course Konoko's head was messed up having the SWAT helmet. So then I replaced that part withTXMPIteration002/k4_head and got this:

It seems everything after the head, lost the textures. But I ran out of time to figure out what's wrong. I did all this using a hex editor.

Here's the file if you're interested. http://edt.oni2.net/AE/TRMAk4_H_001a_high_texture_generic.oni

This will be moved to OBD_talk:TRMA and elsewhere. We shouldn't be spamming the talk page of such a general introduction with modding details.

The hack you just did is correct except for the fact that "TXMPIteration002/k4_head" is one char longer than "TXMPIteration002/TChead".

Thus you pushed all the remaining texture names back one char, screwing up their lookup from the file's header (pointer to first char).

Since the shift was by one char only, the screw-up is very specific: instead of the leading char of the strings, there's a null char.

This basically means that the textures after konoko's head now have an empty string as a filename (the null char terminates a string).

There are 3 ways to avoid such problems.

1. One (not recommended) is to use shorter filenames so they don't shift the following ones. I've been using this for, e.g., "ninjabot2".
2. Another (recomended) is to edit the addresses of the filenames in the header according to the shifts you introduced. It's a bit of work.

In your example, you should edit this part (list of named files):

As you can see, you have to to do quite some hex math, but nothing exceptional.

3. Finally, you can generate this same TRMA by changing links-by-id in OUP.

• typically, you'd reimport the TRMA you want to mix into a dummy .dat

(you'd also import both source TRMAs along with their child TXMPs)

• then you'd use OUP make the new TRMA link to other TRMA's TXMP, by ID.
• finally, you'd export the dummy .dat and have an updated new TRMA*.oni

This may sound cumbersome, but it does the job in this case and many others.

Actually, I'd recommend OUP in all but the simplest cases (such as TRMA).

geyser 15:15, 15 February 2008 (CET)

The actual bastardizing I had in mind doesn't have to do with the TRMA alone.

It's about swapping the geometries of the bones, not just the texture maps.

That implies dealing with the sub-hierarchy of TRBS: TRCM, TRGA, M3GM, TRTA.

That hierarchy is nameless, and you also have to swap between different TRBS.

That means you can't get anything done by hacking a single TRBS*.oni

You have to use OUP on a dummy .dat generated from several TRBS.

Once you have them, you have to swap the IDs of corresponding TRCM/TRGA/M3GM.

You may also want to bastardize the skeletons, that is, swap/edit the TRIA.

geyser 15:15, 15 February 2008 (CET)

Thank you for the explanation, you're right its not that hard, once you understand what's needed. I'll play with it some more after work. I could see the benefits of using the same length filename especially if one is creating new textures for a character, then the issue of texture lookup is avoided.

Bastardizing, seems more of a challenge...

Thanks for your help, now I have a Black ops Konoko. Its was easy to add this character as the default player.
