Hi, terribly sorry for the late reply. Perhaps you've been able to move on by now? All I can really think of from what you've written is to make sure the paths are correct by modifying pathToSkeletonGO in the makeAnimationClip() method and make sure the joint names match in the BVH file. As I previously mentioned before in a different thread BVHImporterExporter was never really intended for Mecanim, though it should work with a bit of extra work. I can't really help with Blender though if that's giving you trouble. Hope you succeed with your goal! Btw you're not making a tool that repackage my tool and give people access to its features, right?
