Thanks Max, sorry - incredibly slow response!
The scene over a period of around half an hour goes from misty and overcast to a kind of deep red and very foggy (as in the shots). I’d like to be able to lighten the shadows (the way the skylight does) and so the change in color needs to be gradual. I guess triggering the color change as suggested couldn’t fade over the time period? I wonder if I could double up the directional lights, one with shadows on and one with them off to fill in a bit?
