What are your colour perspective settings? I use something like: RGB(5,7,9) or RGB(5,10,15) or RGB(9,16,25) or sometimes backward order of values for the sunsets.
In which bit?
The light is coming from HDRI, the sun and ambient bouncing around.
Here is where colour perspective is set, taking over from the default slightly bluish settings of the Bryce standard.
Thanks David, in that case, In my renders, it’s not even switched on.
What does it do, alter the overall colour balance or something?
Essentially it is an aerial perspective control http://en.wikipedia.org/wiki/Aerial_perspective the RGB values you supply is the colour to which the haze will eventually render distant objects. I find the Bryce default somewhat overly blue. And favour the 5,4,0 to 7,5,2 range, which offsets the natural trend. Otherwise, it is just another fun thing to play with.
