I hope the image has uploaded. but broad strokes, I'd feel bad if I just raised an issue and didn't bring any ideas as to how it would work. the idea being that you break the arm in this case into 3 sections. the hand, the shoulder and the elbow. the texture for the elbow is broken down into triangles. 16 in total, these are combined to form 8 triangles that make up the bend. the biggest problems being how top layers would work with this approach and that for each side there are 2 ways of putting the triangles together, so what do you pick
