Mesh Distortion when Retargeting - Seem to be related to FK Chain Settings - Need Guidance

Hey guys!

I am having trouble with Manny’s mesh getting distorted when retargeting some animations with IK rigs and IK retargeter. The source mesh was imported from external source. Only the hands have issues on all the animations, and the head get distorted only on SOME animations

It seems to be related to FK Chain Settings because in the “Global Settings” under “Chain Mapping” within the retargeter, under “Global Retarget Phases” if I disable (untick) “Enable FK” all the weird distortions go away, but the animations are not as good this way (some limbs not following properly)

I would like to be able to fix the “FK” issues and still have it enabled. I should also mention that disabling FK on each problematic chain link individually also makes the distortions go away

If someone could point me in the right deirection here that would be awesome :slight_smile:

Thank you!
