Stuck on a point

What can help identify the point something is getting stuck is to click the mesh icon at the bottom of the scene window. It puts yellow triangles all over your character (inside the yellow outline). As you move the character, it sometimes identifies the spot that is not moving. Then you can check all the layers to see if there is something special at that point. E.g. stray handles can be on layers you did not expect, causing this sort of problem. The yellow mesh can localize where to look a bit better, making it faster to look through all the layers (one by one) for possible causes of the problem. After that, I will often delete and undo different suspect layers (on a copy of the puppet!) to confirm which layer caused the problem. Once the cause of the problem is known, it is much quicker to work out how to fix it.
