So, I have just gone back after a couple of mod updates (automatically on CKAN) and now the sun isn't illuminating the craft or the light side of the planets properly. It seems to create the right haze at the edge of the planet but it is all dark including my ships and my buildings.
Can anyone help please. I have removed graphic mods such as EVE, Distant Object Enhancement.
Try posting a bit more information --

List of mods in use?
What mods did you update before the problem started?
Have you tried to removing -all- visual mods, including Scatterer, TextureReplacer, TexturesUnlimited, Kopernicus, SVE, SVT, etc?
Have you tried a fully clean install (no mods)?
