Hi @Cerbera,
that's an awesome technique that works amazingly well 🙂 Thanks for pointing that out.
Nonetheless it's not quite what I want. I mean that would probably help me get the desired result, but it's not really how I would like to get there.
Here's why: I am actually super happy with the result of the cloth sim and I am also happy with the wrinkles it produces:
The only thing I am not happy with is that I can't get this flat seam part to work. Basically this is what I want (again mocked up in PS):
In order to achieve this flat seam part, my thought was to use the belt tag, which also kind of works:
The only problem is that with the belt tag those points don't move at all. And actually I want them to move, so the could follow the form as in the .gif above. I just don't want those points to inflate. So obviously the belt tag is not the right tool. What I am kind of looking for is a way to specify which parts are effected by the inflation (actually the negative attractor).
Now, I could probably model the basic pouch mesh very easily manually and then add wrinkles like you described, but ultimately I would like to use the inflation as part of an animation. Right now I use this only for product visualization stills but I am searching for a solution that would work as an animation too. And the cloth sim seems so tempting – if I just could get this seam part to work 🙂
Maybe you have some more ideas about this? I'll try @HappyPolygon‘s idea in the meantime! Thanks guys!
