Any ideas as to why the IK bones of my rig are twisting the arm like so? This is of course using rigify.
This doesn't occur with FK bones posed to the same position, it just appears to be happening with Inverse Kinematics.
I've attempted to regenerate the rig multiple times--- I tested multiple bone roll orientations as well as creating a more exaggerated elbow bend, to no avail. I've went through all the IK constraints and haven't found anything obviously wrong there. It occurs on both left and right arms.
This isn't exclusive to this project either, as I had the same issue before with a previous character, I couldn't find a solution there either.
In the file I've hidden non pertinent deformation bones to make seeing the exact twisting problem more clear. Any help regarding this is greatly appreciated!
