We just received several hundred files from a mocap shoot that were retargeted with the mocap data.

We have been cleaning up those files and have started to come across some weird issues with the control rigs.

In some of the files if we drag any of the ik hand controllers it makes the entire rig pop, including the selected controller. It is acting as if there is another set of controls that influence them, but i have scrubbed the entire scene and cannot find any evidence of what might be causing it.

This affects the entire character and makes it near impossible to paste poses, or do anything with the character. I realize it would be hard to diagnose this without the file, but is there anything that anyone has run in to before that may cause this?

It would appear that it is the arm twist bones, if i removed them from the characterization the double solving issue disappears. However, all the animations have already been plotted to the skeleton with these twists applied, is there a way to make it “forget” about the twist bones in the animations besides removing all the keys on the twist bones?
