How do I add ambient occlusion or show shadows for the craters in my moon object? I really don't know how to use nodes so I'm wondering how to use ambient occlusion to show that there are craters on my moon while the moon has emissions on. I want to do this by having some shadows on the craters.
I am also wondering how I can use emissions as a light source because now I am using a sunlight source inside the moon for my background.
I guess there are several solution, but you could simply use the Input &gt; Ambient Occlusion node as a factor between 2 Emission nodes. Use a ColorRamp between the AO and the Mix Shader if you ever need to tweak the contrasts:
