Just wondering If anyone could help me. I have to model a series of bags for a university project and have no idea where to start. This is what I had in mind: A bag on TurboSquid and the order 1886 bags done by Alec Moody: http://www.turbosquid.com/3d-models/3d-model---nike-club-team/683067
Those are 90% sub-d modeling. For the top bag, I did sculpt the crease in the leather where the panels join since that was easier. There might be a better way to do this with cloth sim but I just did it manually with polygons and then used zbrush for a details pass.
