Yeah there have been "issues" with the particle effects, mainly because I didn't resize them together with the meshes, as you may have seen in my other thread, it's a b*tch to manually resize the particle effects ..
I've noticed indeed some of the textures are not matching 100%, I think those were the vanilla textures, I'm thinking of replacing them completely. As for the nightlight, I'll add them in one of my next releases, I've got the same feedback on moddb
And right now there is no real difference between the original files (PlanetTerran) and my files (PlanetTerran_0), I'm working on planet bonuses to add more variation to the existing types and change some of the values on the new planet types.
The moon textures are kinda.. weird, I don't know how to change them to use a new texture, I've tried a few times but it gets all funky :')
