The w-key has options for alignments, but afaik it only works on vertices and not entire faces, so would be pretty tedious with a lot of geometry. In some cases, you can pretty good results by unwrapping using follow active quads or project from view.
(bump) I've tried googling but I don't know what this is called, and blenders relax acts different than max This is stopping me from uving a model In the viewport the model looks like above: [-][-][-] But when I unrwap it in blender it looks like: [][][][][][] with uneven pixel coverage and the faces are all "squished" And…
@frell I made a similar mesh, unwrapped it, applied a uv checker pattern and the pixel ratio is perfect. I can't think of what you may have changed, maybe if you post the .blend we can sort that out. I think the two you mentioned are the only ones. The thing about unwrapping in Blender is that it uses LSCM algorithm, so…
