The best way to import a bone structure to a .blend file
Posted: Mon Jun 10, 2019 5:24 pm
Hello all,
I am currently trying to develop some models for the game Torchlight 2. I've had some success with being able to convert a .mesh.xml to a .obj using a bunch of regular expressions magic, and have made new models from these originals. The issue I'm having right now is that I'd like to reuse the .skeleton animations of the original model for this mod, and that means rigging my model to the original's skeleton.
Two issues:
1. The object file format doesn't have any way to create bones. I have a solution for this (importing bone locations as verts, making bones from the verts), but the rotation of the bones will be incorrect. Then there's also the issue with end bones like fingers not having a vert to orientate the bone, but I could do some math on the rotation unit vector to get a direction.
2. The bigger issue is that it seems like the scales between the mesh.xml and skeleton.xml are off. One example: A vertex on the character's chin has a Z position of ~2.5, but the Z position in the skeleton.xml is 3.51 E-09, basically 0.
I've skimmed the wiki entry on the C++ code for the skeleton file type, but I don't see anything useful about the structure of the skeleton.xml file type. Does anyone happen to have any experience with ripping bones from a compiled ogre mesh? I'd rather not have to create my own skeleton and animations for something that was supposed to be a less than 12 hour simple mod.
