Rigged hand glitch - Help


#1

I have an issue with a rigged hand, where the index finger pops at between frames 140-160 (in 3 seperate animations)
There’s no wonky keyframes, no issues that I can notice in the rig. Just a weird pop with no identifiable cause.

Wondering if anybody with rigging experience could shed some light on what’s going wrong?

The problem disappears when disabling the Xpresso on the controller. A further look shows that you have keyframes on the range mapper node for p-rotation that changes the mapping range. The key sits on frame 152. That causes the glitch. An accidental keyframe?
