How to map cube uvs from existing tilesheet? I have a tilesheet with 128x128px tiles with 2px offsets. When I unwrap a cube to map faces to the tilesheet, I can't figure out how to accurately scale the face uvs so that they are exactly 128px. I'm currently trying to eye it, but my uvs end up being imprecise.

Is there a correct way to unwrap cube faces to a tilesheet?

Thanks!
Enable Snap to Pixels in UV editor > Header > UVs to snap UVs exactly.


Use the Reset unwrap method (U, R) to unwrap all the faces of the cube over the whole UV space.
Scale (S) the resulting UV faces down to the area you want.
Select faces on the cube and reposition/rotate their corresponding UV face accordingly.
