Skeleton files - Star Wars: Ep III - RotS (2005) [XBOX]

Hello, again...on this game, I noticed that in the game files, there is a .ban file in each folder of a character next to the 3d model. I "THINK" these .ban files are the skeletons of the characters but I don't know how to open them. If someone has the talent to examine them, it would be really nice :]

Thank you

Why do you think so? The first 3040 bytes block looks like so:

Then follow blocks with many identical bytes. I don't see how to get valuable information/skeleton data (?) from the bytes with blue underlinings:

There're 752 offsets followed by the same amount of entries with the same stride 0x30 in the ban file. 752 bones for one model would sound insane for a 2005 game.
Obviously the bones are in the same file as the model.

Loading the skeleton via Noesis and the model via AMR:

Noesis code for this file:

Code: Select all

def noepyLoadModel(data, mdlList):
	bs = NoeBitStream(data)
	bs.seek(0x1A4A0, NOESEEK_ABS)
	boneCount = bs.readUInt()
	bones = []
	for i in range(0, boneCount):
		pos = bs.tell() + 0x20
		boneName = bs.readString()
		bs.seek(pos, NOESEEK_ABS)
		boneMat = NoeMat43.fromBytes(bs.readBytes(48)).transpose().inverse()
		bonePIndex = bs.readShort()
		bones.append(NoeBone(i, boneName, boneMat, None, bonePIndex))
	
	mdl = NoeModel()
	mdl.setBones(bones)
	mdlList.append(mdl)
	return 1

It's awesome! So by examining the animation files .bnm you think it could work?

Thing is, I don't deal with animation data.

okay that's not a problem. Just how did you find the skeleton? I will do the same thing for the other characters

Here's a Noesis script that'll import the meshes and the skeletons from the msh samples you uploaded.

Thank you so much! :]

edit: here are .msh files that don't work, thank you for your time and attention :)

Hello!,
there are some .msh that bug or don't work with the plugin. There are also .msh levels files which have a lot of 3d models (small).

I also have a question, is the rigging information for the characters in the .msh files?

Thank you again! :)

Of course, they just weren't handled back then though.

Script updated at the same post. Skin info is supported now.

Tested on all samples found in this thread up to now and everything works fine.

Thank you so much, levels files work very well! (just maybe 1 or 2 missing polygon, but it can be fixed by hand)
There are just the last .msh files that do not work: (hope it will not create other bug :mrgreen: )

The script now handles triangle/triangle strip encoding correctly so it's unlikely to miss anything.
