I'm migrating from 3DS Max to blender and its totaly confusing.
Right now I'm stuck because when I do 'Mesh->UV Unwrap->Unwrap' nothing shows in the UV/Image editor window.
I did a render of some object and since then I don't see the mesh in uv coords.
I noticed there were some kind of masks/layers and it's totaly non-intuitive.
Here is a screenshot: so, how to see the UV mesh?
