I've successfully captured motions of myself and several friends, and I'm very happy with how the software is working. I've imported the .bvh files into Blender, but I'm running into difficulties applying a mesh to the armature.

The problem is that the hierarchy portion of ipisoft bvh files define a "pile of bones" that then get unfolded within the motion portion of the files. What Blender expects is that the bones as defined in the hierarchy fully constitute a T Pose; which is to say that the first "T-Pose" frame of the motion section have all rotations set to zero.

I tried recasting the hierarchy section in a more Blender-friendly form. The file imports into Blender just fine, and it looks identical to the original ipisoft file, but I can't get ipisoft to import my restructured file as a target character ("Import string was not in a correct format.")

Any suggestions?

Here is the file I constructed:

Please remove the empty string between "Frames:" and "Frame Time:" in your BVH file. It will fix the problem.
