Before doing any unwrapping, if you select all the faces and open the UV map window, there is a display of what appears to be a UV map stretched out to fill most of the UV image. Once any unwrap operation is done, it seems to be gone forever.
Is there a way to get that UV mapping when doing unwrap? It is very close to the mapping I want to use in Blue Mars for avatar skin painting.
Also in 2.53, is there any way to control the way the UV unwrapping is done? 2.49 had lots of parameters for the different unwrapping methods, but they seem unavailable in 2.53.
