Currently the material browser shows everything as a sphere. It would be nice to be able to choose a sheet or a cube. If possible it would be even nicer to make this choice on a per material basis. It would be REALLY awesome if you could pick a custom mesh for each material, but that’s not as important.
Oh and I’m not talking about the preview in the material editor. I know how to switch that around. It would be nice if it would remember that I switched it to a cube or a sheet or a custom mesh.
I see that it remembers the mesh in the editor, but none of the other options.
