I mentioned in the chat that I had an idea to allow use the switching of canvases more easily when they are attached in to a moving limb.
The following sample shows how to handle hands using several hands gestures in a particular library. I think that it can be done on a higer level so you can control the hand canvas form an outer level. Now I don’t have so much time to explain it. Open the file and dig it. Ask if you don’t understand how I did it.
