Physical sky is yellow

[falardeau.casey]

I am new to Twilight and I could have sworn that the default physical sky was blue. Now it is yellow. I don't know what I did. Can I reset the default environmental settings?

Your Turbidity setting may be too high or too low. As turbidity increases, the sky becomes more "dirty". The default is 2.0. Below 1.5, weird things start to happen.

It could also be your time of day. At sunset/sunrise, the sky will naturally be more red/yellow.

I had the same problem. Fixed it by matching the UTC time in shadow settings to my
geo location of my model. Hope this helps.

Cheers
