Hello guys!
I would like to ask about bones import tutorial. There are nice tutorials about models import, and to me personally they helped a lot. But alsmost no info on bones import, it would be awesome if someone will make tutorial in MaxScript with a couple of examples how bones are stored and how they could be imported. Maybe someone will be interested explain this to me, then I'll be glad to pay money for such service. Please, write here or send me PM.
P.S. I've attached armature file, this file I would like to import. This file could be an example in tutorial.

Do you have the format specification of that skel file?

Nope, I don't think so. It's unsuitable for a tutorial because it consists of
230 bones/helpers. (About 100 being phy_... helpers?)
Anyway, this is the structure:

Once we found out how the parenting of bones is working here the meaning of the unknown 10 floats should be solved.
If it were less bones I would convert this to a "havok skeleton" but as I said "it's a bad example", imho.
As soon as I have a better one I would like to make a tut. But I've little time and I'm no expert with this.

I already posted a script for this.
The game is Black Desert Online.
viewtopic.php?f=16&t=10909
Code: Select all
boneCount = bs.readUShort()
for i in range(0, boneCount):
boneHash = bs.readUInt()
boneNameSize = bs.readUByte()
boneName = bs.readBytes(boneNameSize).decode("ASCII").rstrip("\0")
boneParent = bs.readInt()
boneMtx = NoeMat44.fromBytes(bs.readBytes(64)).toMat43()
boneMtxInverse = NoeMat44.fromBytes(bs.readBytes(64)).toMat43().inverse()
boneMtxLocal = NoeMat44.fromBytes(bs.readBytes(64)).toMat43()
boneMtxLocalInverse = NoeMat44.fromBytes(bs.readBytes(64)).toMat43().inverse()
boneScale = NoeVec3.fromBytes(bs.readBytes(12))
BoneQuat = NoeQuat.fromBytes(bs.readBytes(16))
BonePos = NoeVec3.fromBytes(bs.readBytes(12))
bs.seek(0x2, NOESEEK_REL)
newBone = NoeBone(i, boneName, boneMtx, None, boneParent)
boneList.append(newBone)

thx, chrrox.
(I'll never understand why thread openers hide the names of the games.
