This is driving me crazy. I am relatively new in Blender (2.8), but I've been working with 3D app (Houdini) a lot of years. I am trying to model a simple cigarretes packs. I modeled it and UV it without issues, but when I added bevel to some edges, UV map going nuts and distorts:
The left one is the basic UV cube. Note the cut when box opens. I've tried everything that I've found in forums: Inset faces, adding loopcuts, subdividing faces, separates every faces of the model, adding seams in all edges, and nothing. Distortion appears anyways.
Any clue? Thanks in advance.
