I must say. This is a hugely underrated tool! Its perfect for low orbit renderings and insanely fast to render. (Especially compared to a volume atmosphere)
However, it’s a pity that it is so limited in several ways.
For instance, it would be awesome to be able to add a cloud layer!
When going to the node editor, I noticed that the planetary environment is missing an input for the ground albedo. When adding a texture, the texture node isn’t connected to anything. (screenshot)
This is especially unfortunate since otherwise, I could simply mix the cloud layer and the base layer together if there was something to attach it to.
Apart from this, it would be a huge improvement to have some parameters to art direct the atmosphere, like colour, thickness and spread.
