A few features I can't find that I suspect are there.
1. Align selected shells to edges / corners of 0-1 space. In Maya for example you can align to top left, top right, bottom left, bottom right, center top, center right, center bottom, center left.
I can't find a feature like this in Rizom but suspect it exists.
2. Ungroup stacked group. Once stacked I can't workout how to ungroup a stack group.
3. What to do with unneeded UV shells?Let's say I make a modular wall piece and know that the left and right faces will never be seen. Is there a way I can just delete these shells?
It doesn't really matter and I could just leave these shells scaled extremely small and overlapping or outside of the 0-1 space, but deletion would be cleaner. A hide feature would work almost as well.
4. Rotation snap feature. Is there a way to snap to degree increments when rotating shells? If not is there a feature that will easily straighten a rotated shell to the nearest 90 degree rotation.
