I have an orientation interpolator which I can get rotations out of. There is a way to get a new Blender matrix_world from a local rotation, and i could probably decompose it to get out a different rotation. Perhaps I could use this. Hmm. I don’t know how to keyframe a matrix multiplication or decomposition though, just a rotation. Maybe I can get a good rotation and throw in an empty parent to the (joint) object hierarchy object? Maybe the key is to add an empty object above every joint?

Just when you want to give up, try the attached.This is just a bare loa4 with all Joint and Segment and Site nodes. If you can import this transform hierarchy, then we can just add geometry wherever, no skin now. Joint and Segment and Site are just Transforms with some special fields, none of which are used in this basic import. If it won't let you call it a Joint or Segment or Site, then use the DEF name with Joint or Segment, or Site in front. Good Luck. This should be able to be imported into anything, with some care. The objective is to get away from the authoring tool default skeleton or armature or whatever, and be easy to pick this one and change dimensions as desired. Then you start with a good skeleton and go forward.Thanks,Joe
