Hello,
I hope I'm just unable to find appropriate SOPs. So how to do these actions, described in subject. For now I was able only to emulate swapping of UVs, by running a Carve and Skin SOP. But, how to inverse curve, or inverse normals of nurbs Surface ? By ‘inverse normals’, I of course meant something like skinning along inverted curves, not how tessellated mesh is displayed.
