@much said: Hi. I am new to the sketchy physics and would liketo ask an advice from the experts. I have a cylinder which is being turned around and I would like to cover it with a masking tape, with a different color (as the cylinder is being turned). Does anyone have an idea how i will do it? Thank you. much. There might be a way to fake it using a slider and a rotating "barber poll" kind of texture. But, even though it was suggested elsewhere that it might might be possible to make something out of joints and flat pieces I think you would find it tedious and the results disappointing. Sorry, its just not something this physics engine does well.
