As I see now I´ve chosen a bad angle, so that you see all the stretched textures and from this perspective there is not much sky to see. So I´m working on an new version, I´ve started last night but was too tired to finish, think I´ll update that later.
Hm about the lightning, I´m using the UTM light model, but im not satisfied - I think its too bright - even after lowering it into the ground.
Still havent tried to tint it down, maye this will solve the brightness.
But thx so far
