Gas Giant Custom Lighting

This is relevant to custom lighting setup for gas giants.

For custom space lighting information, go here.

Both flow simulation and legacy shaders support procedural smoothness and normal maps to make the gas giant look more dynamic and planetary.

Smoothness

Smoothness affects how shiny the sun reflections are on the gas giants. See below for a comparison photo of different smoothness values on the same gas giant:

Smoothness is also adjustable for gas giant rings:

Normals

Normals simulate depth on the gas giant surface, so it doesn't look like a perfectly smooth sphere. This effect is quite muted and stands out the most on the areas of the gas giant that face away from the sun.
