hi
i am having issues with the arms. See video link :
Arms are set to FK…

Any ideas why this is happening?
Thank you
David
no one had this issue so far?
I saw something similar once but in IK mode.
Out of curiosity, if you switch to IK on those keyframed poses (40 and 44) did it still jiggle?
You haven’t given much info, and your controllers are hiding on playback.
Is it the controller that’s jiggling? Or the bones? Or some driving rig components? Trace down the graph and find out where the jiggling is actually originating from. Without seeing more about your rig, it’s difficult to guess.
If it’s just the controllers, you could try running an Euler filter, or changing the rotation order.
Hey Chris
I am helping out with some students and one of them have this same issue. Quick poke through the node graph and it seems to be coming from the mgear_ikfk2Bone node. Specifically the out center plug that gets decomposed and plugged into a transform. That connection seems to be flipping 180. Only happening on the right side of this specific scene.
Maya 2022.3
MGear 4.0.9
Attached the rig file and a video demoing the issue.
Any help would be greatly apricated!

here you can see a video screen grab. Seems to me that those Arm twist joints are flippinghttps://we.tl/t-UhzT9aSEaO
Hi @Justin thanks for the extra details!
I notice your rig is rigged with straight arms. And I wonder if that is the cause. You didn’t include your guide, so I can’t 100% tell.
@actoratwork Is your rig also rigged with very straight arms? If you both did, I would say that is the biggest clue.
My guess right now is that when it is rigged perfectly (or close to) straight, it might have an ambiguous alignment that is causing this flipping.
- You can try rigging a test version with a bit of bend to your arm, and see if it fixes it.
- If you can’t do that, as a temporary hacky patch, you can adjust the input to mgear_ikfk2Bone2.blend - Just run it through a remapValue node that goes from 0.0 - 1.0 input → 0.0001 - 1.0 output
If the blend never reached 100% 0.0 it seems to fix the flip. And 0.0001 is close enough you shouldn’t see a difference. But I only lightly tested this. No guarantees!

Ahhh that was it, Chris you’re a legend!
Feeling silly for not seeing that sooner.
Thanks again!
