Sometimes the moons look like this:

idk why. Obviously it is some freaky combination of transparency/lighting issues, but I don't know where to start. I've modded and tweaked too many things. Someone else must have had this problem before and figured it out, right?

At other times, they look okay:

...or inbetween:

you installed anything by SWG? like his translucent moons?

Quite probably. Is the transparency on them busted? Or are they incompatible with something else I'm doing?
