hi.
i have a problem with retargeting a C3D mocap file (captured using VICON) on my character face .
I want to remove the overall head movement and rotation , so that i could transfer markers animation to appropriate face controller without any extra head motions .
I know that FaceRobot can do somthing like what i want but i prefer to do this via 3ds max .
I attached both C3d file and FBX (converted to fbx via motion builder . you can import it to 3ds max) .
""i could remove head movement using a reverse movement between markers root and markers above head … but head rotation is still exist 
please spend some of your time to solve this prob
thanks in advance .
