I've been trying to figure the same thing out (mid-air sommersault, flip, handstand etc.). When I select the pelvis and the platforms and do a rotate (character off ground) I get two different results (depending on Use Transform Coordinate Center setting interaction) Either the platforms are rotating on their own axes (when selected and rotated with pelvis - Auto Key on) or I can get the overall rotation effect I'm seeking but the rotation center is based in the Parent (therefore offset from the hips.)
I can get close to what I need to do by rotating transform gizmo for the layer but the center of that rotation is offset from the pelvis. Am I supposed to change the pivot point center for the animation layer transform gizmo?
I'll check out the indicated CAT forum. Thanks to all for any any advice.
Thanks!
