Figure out how the animation will work, then work backwards to design the coiled vs extended states. It could be that the coiled ribbon is simply scaled inwards as the separate ribbon unfurls. To mimic the ribbon unspooling.
Well, the coiled status is just the central cylinder with the ribbon simulated by a normal map + albedo: the extended one is a long flat strip capping from the handle to the cylinder notch. How could it be the same?
Hi. I have to uvmap a model (kind a yoyo, which cord is a ribbon) having two main states: one in quiet (ribbon coiled) and one extended. Do I have to model two sets of polygons for them and map in separate sections of the uvmap, hiding and showing them accordingly to the respective animation? Or what else?
