I'm attempting to do an unwrap of a surface that I brought in from another application (Rhino), anddddd as I've heard, it is a nightmare. The IGES file came in as a series of small patch surfaces, with which I couldn't join and couldn't create edge loops that extended past 1 surface patch. I did the Convert>Convert NURBS to Polygons, with Attach Multiple Output Meshes selected. After that, I was able to create an edge loop across the patches using the Multi Cut Tool, but I don't know where to go from here for the unwrapping. Every tutorial that I watch says to start with a Planar Projection in the UV Texture Editor, but when I select the model and try to do a Planar Project, nothing happens. I was able to get a projection using Cylindrical Mapping, but it is pretty rough. I've also tried importing the surface as a SAT file with the same results.
Recreating the surface from scratch in Maya is not an option (it was created from a 3D scan). Has anyone run into these issues before? Is there a solid workflow for unwrapping surfaces imported from the outside?
Thanks in advance for taking a look. Virtual rounds of drinks are in order
