<div dir="auto">I also looked up is where centers are handled for HAnimJoints in the Blender x3d import Transform code (where we create an object’s matrix_world for Transform and HAnim nodes). This was one thing I am confused as to why some locations for Joints are at 0,0,0 in the Blender GUI. Perhaps I need to get the real (DEF) node to get fields? This seems like a good thing to do, looking at code. Another place to push better solutions in. I’ll throw some debugging in to check for whether the joint center field is actually retrieved from X3D, or if that’s handled during preprocessing.</div><div dir="auto"><br></div><div dir="auto">If anyone is following along, I’m referring to the “translateTransform” function in the Blender addon io_scene_x3d/import_x3d.py.

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
