I've been asking for a tutorial on design wrapping/displacement maps. Specifically for folds in tshirts in product mockups. I've explained it thoroughly but it's like all I get is some really basic tutorial that might be useful to a first year design student. It's like they search for a word without actually reding what I wrote. I got sent to one about making car wraps too. I've been using Draw since the nineties. I've made these things for real. This isn't helpful. It's insulting.
Or... instead you maybe you want realistic mock-ups based on shirt geometry (possibly even animated)?
