distortion of out line with bones

I’m sure this question is already answered somewhere but I can’t find it. If anyone knows where please let me know. I am having issues with the outline at the bone joints distorting when bending. I have a robot arm made from two parts, the upper and lower sections. When the arm is bent the forearm which is parented of course to the upper arm distorts at the elbow. I am used to anime studio which this problem is very easy to fix. I am new to toon boom studio and am stumped.


It’s difficult to give advice unless we can actually see the character or scene. I recommend contacting support and providing the character template or scene.

maybe you find some fixing-methods in this tutorials:
