Yes, @eric-s, we should first move this discussion into a dedicated post (for not to change the meaning of Eve’s discussion).
I have created a few projects to work on for this reason, to improve my workflow on creating&texturing terrains, cliffs and rocks.
I’ve already put two of my hobby-projects (grk-house & grk-lighthouse) in my album,but we better make a special album for that, and I’m testing different ways to make UV unwrap and UV map as simple as possible and to look better for render and animation (in Unity).
