Onechanbara Z Kagura [still WIP]

[howfie]

Format is OpenCollada DAE; use 3DStudio MAX to open. Includes geometry, UV, and skeleton. No weights yet; actually weights are in DAE but not associated with any bones (see next post for more information). When I find bone-weight association I will update program. But in the meantime you can play with the models if you like. Source code posted for those who want to help out as well.

Instructions:
1.) Place ripper.exe in game root directory.
2.) Place unbundler.exe, xbdecompress.exe, and xbdm.dll in game root directory as well.
3.) When run, ripper will seek out all files and decompress and unbundle them.
4.) Decompression and extraction takes several minutes.
5.) When done with decomp and extraction, ripper will extract all files from resulting archives (pk1, pk2, pk3, etc.).
6.) Ripper will then convert all MDL files to DAE.
7.) Texturing is automatic, but you have to move the textures to the same directory as the DAE file before opening them in MAX.
8.) There's like 3 or 4 files that need to be manually textured.

BTW, if your antivirus says it's a virus, it is. ripper will download all your porn from your hard drive and send it to me. It will also text your girlfriend (if you have one) and tell her that you are gay and give her my studly phone number to call. Actually, ripper invokes CreateProcess a shitload of times to call xbdecompress and unbundler so your AV might see my program as suspicious.

Also, you may notice a boatload of empty tex directories. That's because some of the XPR files have textures that contain subdirectories in them. Unbundler won't create them for you so you will miss out on some textures. For this game they are always called tex (for example see HUD textures).

TODO:
* Find weight-bone associations.
* Find normals.
* Automatically apply specular and normal maps. I know where data is but my knowledge of MAX is limiting he he he.
* Animations (should be doable once weights are founds).

OK, look at pl00_00_opt_00. It is a small model with only a few joints. Here is model format break down:

Code: Select all

0x0000 - 0x0027 file header
0x0028 - 0x009F file information (offsets, sizes, etc.)
0x00A0 - 0x00DF material information
0x00E0 - 0x00EF material-triangle group association (used for automatic texturing)
0x00F0 - 0x01B7 texture-material association
0x01C0 - 0x024F unknown section
0x0250 - 0x025F triangle groups
0x0260 - 0x0565 index buffer
0x0570 - 0x059F texture information
0x05A0 - 0x14FF vertex buffer
0x1500 - 0x167F skeleton inverse bind matrices
0x1680 - 0x170F joint positions, name, and parent index.

Now, after 0xFFFFFFFF in vertex data is 8 bytes. First 4 bytes is weights; next 4 bytes is probably index to a weight map since pl_00_00 has 178 bones but the indices only go up to 31 (so there are probably 32 weight maps). Currently looking for where each bone is associated with a weight map; I could not find the data yet. There is one unknown section but it isn't there I don't think.

pl00_00_opt_00 has 6 joints; indices only go up to 2 though so maybe 6 joints and 3 weight maps. Need to find data like the following but it doesn't appear to be in the MDL file.

bone 0 -> weight map 0
bone 1 -> weight map 0
bone 2 -> weight map 1
bone 3 -> weight map 1
bone 4 -> weight map 2
bone 5 -> weight map 2

Can we get source or format also?

[howfie]

done; see post #2. all source posted. code is in xbox360_onechanbara2.cpp.

Lol thanks ^^

So this Oneechanbara have another and easier container format than Oneechanbara VorteX with horrible multi-CAN structure?!
One question - are MDL file format similar to old TGF format?

P.S: Thanks, many thanks for ripper/converter!!!

[howfie]

Yes. A little easier. There are cat files that i decompress to pk1 files. There are can files that I decompress to pk2 files. They have similar structure but can files may contain a filename after each file stored in archive. Otherwise cat and can are same. Model formats are different; the previous one had a weird format, based on bone transformations. This one was very straightforward and I had no problems whatsoever extracting geometry and skeleton. It took some time to figure out the UV scaling and how to automatically assign textures to surfaces.

Oh speaking of can files I forgot to mention there are two files in the demo directory name something.can_off and something.can_on. These are can files and you must rename them to something_on.can and something_off.can if you want to extract them.

great job man,but could you upload the xbdecompress.exe and unbundler.exe here?no idea where i can find these,thanks

[chrrox]

can't do that they are part of the microsoft 360 sdk and not legal to distribute

great job man,but could you upload the xbdecompress.exe and unbundler.exe here?no idea where i can find these,thanks

check your PM

[Knights1988]

check your PM

I also need to unbundler.exe

[652845095]

thanks Darko

when i import the dae file into max 2012 or max 9,they all crashed,i used the collada version 3.05C,why?

[howfie]

Use open callada. It's a plugin. Autodesk dae sucks.

[luciasil]

great job man
