I'm trying to model something that is nearly identical to this >> https://www.turbosquid.com/3d-models/3d-model-realistic-food-packaging-01-1205979
I would just purchase that model if I didn't need various sizes for my company's product line... and I know that scaling the model just wouldn't quite make things look right when all the products are shown together.
The basic structure and shape are simple to model.
I can use a deformer to get some of the more subtle random curves and warping.
I've added some of the wrinkles in the packaging with a bump map.
But how do I get all of those really detailed wrinkles along the edges, and how would you go about modeling the zipper and the tiny details around it?
