UV Map Distorts when I add bevel to model's edges 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.
When you change the topology of your object with the bevel, it changes its UV. I don't know how it works with Houdini but in Blender you need to make sure that the seams are still ok, unwrap again, and align again with the image texture in the UV editor.
