Thanks, that works. Also instead select all verts I need to select the ones that share the same distance to 0, otherwise it simply shift all selected keeping proportional distances. Scaling all verts with only scale vertical also works fine.
@monster wouldn't that mean you'd have to select the offending verts one by one to flatten them that way? Or are you aware of a way to change it from moving center of the selection only to individual verts in unwrap?
How can I zero it when in UW? That solves the problem, but the only way to move the verts to 0 that I can see is to select them and move them manually, that seems cumbersome and imprecise. I suppose there is a better way to do it.
Here I have peeled a UV island. Relaxed it and the space between the vertical lines are correct. but if I use the straighten tool it sort of ignores/automates the distancing between each segment. In Modo it seems to do a better job of calculating this when straightening. Is there anything I can do with Max's unwrap tools…
I had a few times that issue and I had the impression it was a bug. I solved it selecting the full object and applying a "quick planar map". Nothing else seem to work. Then doing exactly the same seams and UV steps the straighten tool works perfectly. Problem: Solution (or at least works for me) quick planar of the full…
