Animation editor duplicates Motor6Ds and permanently messes up the rig when using IK with extra parts

The rig I’m using has a Handle attached to the RightHand with a Motor6D. It’s just one part with a mesh welded (WeldConstraint) to it.

This is what happens when I tried to use IK with it.


I was moving the right arm around, then moving the handle, then moving the left arm around, then I came back to the Right Arm only for this to happen:

It permanently bricks the rig until you delete the extra joints and then the pose gets screwed up in Studio, even when the Animation Editor isn’t active.

Is there any progress on this?

Thanks for bringing this to my attention and for the repro file! I will investigate this now!

Edit: seems like there is a bad link for the repro file. Could you re-upload or send as PM? Thanks

I’ll try PM!

Have you been able to figure out the issue yet?

Yes, a fix for this is on the way!
