My first question !
This image shows how Blender manages a spherical projection in the uv editor. For a simple sphere (UV sphere, 12 segments, 12 rings) there’s so many faces and vertices which are out of range and such a large part of the image that is not mapped ! Is there no way to get out of that mess or avoid it ? BTW, the cylindrical mapping isn’t any better…
Moving the vertices is obviously not an option, especially when the sphere has even more faces.
I also know about the spherical image mapping in the F5 buttons. But I need uv mapping here.
