I have a mesh with multiple materials on it.
Part of it is a brick wall.
I have loaded a brick wall texture and I can see it.
I place the mesh in edit mode and deselect all faces except the faces belonging to the material id of the brick wall.
I press U to unwrap those faces, I use Smart Projection.
I see the UV mapping scheme displayed in the image editor.
Now I return to the image editor and select the brick wall texture I can see in the list, but it never loads into the area I just unwrapped.
I do see the mapping being applied to the mesh in the 3D viewport.
Am I missing something? I assumed Blender could do a UV map for each material in a multi-material mesh. Is this assumption flawed? If so, how do I map, just part of my mesh?
