I hate saying this but I am using the IPIsoft Mocap Rig, why because all the motion transfer tools I have attempted in Blender BVhacker etc don’t like retargeting the motion to an advanced IK Skeleton. But if I match the IPI Skeleton all motion is converted quickly and easily. Since I can’t animate for **** and we don’t have a real animator it works out just fine.
Ya I know for some custom frames or fixes its a pain not having the marionette controls but I don’t need to use them very often.
