I'm a beginner and after modeling a "pretty complex" house that I want to refine in Zbrush, I took a fairly long time UV Mapping it. Here's some questions that came to my mind:
1 - Is there a way to "auto rotate" every pieces so they all "face the same direction" ? When I unfold a few pieces and orient the shells, they tend to rotate. This is not ideal if I want to add a directional texture afterwards.
2 - Is there a way for the "layout" to keep stacked shells ... stacked? When I layout my shells, the stacked ones are spread everywhere.
3 - Is there a way to "group shells" so when I do a layout, they stay aside? It would be really convenient afterwards when I want to texture it. To avoid having, for exemple, a part of my roof on the top right corner of my UV map and the other part of my roof on the bottom left corner.
4 - I found myself switching between the legacy Unfold and Unfold3D quite a lot... is that common? The rescale option from the legacy one was really usefull while the Unfold3D would some time give me less distortion.
Thanks a lot for your time and help !
