Hi
this is a bug already in the 2.4x series
when you assign a bevel modifier to a UV mapped cube
the UVmap coordinates are modified
see the attached image and the blend file
the only solution is to apply the bevel modifier
and remap the UV
expected behaviour is to have the UV correctly centered
let me know if you need more info
thks

It's actually worse than demonstrated in the images. Not only does it fall "out of center," but, the whole concept of UVs was ignored (I think) as I do some tests and examine the code. Bevel created entirely new faces. How do they receive UVs? A simple experiment with adding seams to a cube, unwrapping, then attaching and applying a bevel modifier shows some serious chaos in the results.
Another issue is that this uses what looks like a snippet of BMesh to do it's thing, so it's a little unfamiliar.
This seems like a bug/feature request actually, because simply making the newly created bevel faces contain the full UV space doesn't feel all that useful :) Thinking through the problem, I'm going to try to have the new UVs created by projecting along the normals of their constituent vertices, and interpolating UVs from the unmodified mesh where the projection strikes.
