Is there a way to edit mesh with fixed UVs?

Hello, I want to cut something out from atlas, but when I try to move vertices around it messes UVs. Is there a way to toggle UVs as projected / constant or something? I used this feature in 3dsmax…
Please help!

Instead of moving, slide the vertices. Use the knife tool or loopcuts for cutting. All these preserve UVs.

There is a uv project modifier.

not OP but: awesome, that solves a problem I had for quite a while. thanks :slight_smile:

Thank you very much, exactly what I needed. Except, for some reason the projected texture was 2x scaled.
