This is a bit tricky. What you really want is a volumetric (true 3D)
sphere for the atmosphere, and one for the clouds. Carrara does not
have them. Other than projecting clouds on the surface of a sphere
(no depth, but good from a distance), there 's not too much. Texture
map would do for the weather pattern, though.
Best you can do is a volumetric cloud, about a little bigger than the
planet, then work with that. The atmospheric glow can be simulated by
putting a color in the glow channel of the sphere that you use for the
atmosphere.
