In a KineFX chain, can I fix a joint's rotation in place (at a certain frame) so the joint is fixed at this angle for the whole motion clip? I have a short anim imported from an FBX. I used Rig Pose to re-pose the arms. One of the arm joints has a slight wobble, probably inherited from the original anim. I want to eliminate this wobble by fixing this joint's rotation in place, so it's held throughout.

the easiest may be to make sure you have rest_transform attribute that stores your static rest pose, you can use Rig Stash Pose for that before you apply any anim (or plug static pose to second input)

then on your Rig Pose SOP you can set the joint Mode to: From Rest Pose
and it will represent the offset from local rest pose of that joint no matter the input animation

you can alternatively just use Override mode, nut then you will have to set the whole joint transform including translation offset also which is often not ideal, so offset from rest pose may be the most infuitive

Thanks, stashing a rest pose worked.
