Post-Overlay Movement Issue: Legs Tangle When Using Mover 5.7

Development Programming & Scripting

Hello,

I’m experiencing an issue on version 5.7. After using an overlay that restricts movement to only one arm (e.g., hand_r and lowerarm_r), my character’s legs begin to tangle or behave erratically when I try to move them using the Mover component.

I have already tried setting both thigh_r and thigh_l bone weights to -1 in the Layered blend per bone node, but this had absolutely no effect on the problem.
Changing the Blend Mode from Branch Filter to Blend Mask and explicitly configuring the mask within the animation asset itself also didn’t help.

After further testing, I discovered that the issue was resolved by reordering the animation layers.

In my original setup, the Overlay layer was positioned after Aim Offset Layer. Moving the Overlay layer to be before the Aim Offset Layer (as shown in the screenshot) completely fixed the leg tangling problem when using the Mover component.
