@lucafeelgood Is a Miku Miku Dance aniamation, (a ".vmd" format..). The F-Curves in rotation seems good in the PMX model. I use "MMD4Maya", then, send to MotionBuilder or save as fbx.. After filterig in MOBU by "smooth", and "peak removal, and "key reducing" at 0.2 in "Precision", and bake my definition of character of G8F, to Rig Control, even the skeleton, is seems fine all... The problem is the convertion to duf, coz the aniblock is rigth, but the duf...
Unfathomable mysteries typical in Daz... 😀
