Hi i'll start a new topic because my first one was a little confusing.
I asked to be able to texture and colorize 3D model made in a 3D modeling software. So what I meant is to be able to import UV unwrap. Because the way I see it is Affinity Designer could do amazing job as a UX/UI design tool, for concept art and if it could do this (import UV unwrap) than I could certainly ditch Illustrator and Photoshop at the same time and reduce my pipeline of tools. Thank You
