I have asked this question before, but I never received a definitive response. In short.....is there a way to disable the default P3D night lighting? What I mean by this are those "light splashes" that are scattered over the terrain when default scenery is rendered at night. The reason I would like to do this is because I have some photoscenery that has default night lighting "bleeding through" in certain locations. For the record, I do not fly over default P3D terrain at all, so I have no need for the default night lighting.

Where are these textures located?

You may look for "simmershome slim lights". It mainly describes how to disable FTX lights but as far as I understood it does also disable the terrain underlays. Unfortunately, it is a quite complicated procedure, at least for me. I tried it once but did not succeed so I went back to "normal".

Hi Chris,

Same boat as you - I use photoscenery exclusively. From what you are saying I suspect you are missing the night variation in your scenery BGLs. You can check very easily with a tool in the SDK - tmfviewer. Open one of your photoscenery BGLs with that, the menu will list the variations. If night is not available it means the developer didn’t do a night version, which means the default sim night texture will show through. There is no other way to disable the default night texture that you are seeing - basically one photoscenery file must have a day texture (you have that) and a night texture (probably missing that). 
 

If you read through the terrain section of the SDK manual it should be clearer - the resample section in particular. That explains how photoscenery is made, including seasons and night textures.
