RJVB09/NiftyNebulae ? reverse-engineered prompt

Build me a Kerbal Space Program mod that adds nice looking 3D volumetric nebulae in space, similar to the dreamy nebula clouds you see in SpaceEngine or Elite Dangerous.

I want it to work as a normal KSP plugin, with the nebula appearance handled in game and tied into the sky and universe view so it feels like part of the space environment. It should be something planet pack makers can reuse too, so make it easy to configure nebula settings from a simple config file and keep the renderer flexible.

Use the existing shader and rendering code in this project as the base, and make sure the mod loads cleanly, creates the nebula visuals, and doesn’t break the game or tank performance too badly. If you need to check current KSP or Unity docs to make sure the implementation is compatible, go ahead and look them up.
