I read in the manual that the contour subprojection is good for unwrapping the area on the beer bottle where the body meets the neck. Unfortunately, I couldn't find how to do it. I saw how to do a curved road, but this is different. Picking session - what do I pick? It's not like the road example they demonstrate...
I've been wondering this for a while, and now have an object that need's this - a lampshade that's basically the same shape as the beer bottle "bridge".
