Very nice update,it opens up new possibilities.
Just, they may or may also have tags like atmosphere and clouds ? Would be handy for bases (like the Europa base by JackDole) or ships like O'Neil or see halo stations.
The method would be to create a parameter specifying which materials have an atmosphere (idem for water, clouds, ...) as well as an offset to turn it if it is in the wrong direction. By default, is auto-adjust but if you specific a shader like "Sphere", it is the method/shader actual for atmosphere,... or specific the path of the shader.
