Okay! I have run into the lhang_tag_bone problem, it wouldn't compile even after I renamed it to lhand_tag_bone. No bone or mesh moves along with it when I move it, it was never included in any weighting process (no tutorial told me to..). I tried simply adding it to the left hand without influencing any vertices (it had absolutely no weight values in that list thing), and I'm using the JO humanoid file. But "lhand_tag_bone" was not found when using Assimilate. I've seen and tried to learn from others with this problem, but to no use. It's a stick figure model, just to learn the trade.
Do you have an idea?
