When moving normally in the ARMA verse the sky gets extremely bright. It gets bright turquoise color and the clouds have no details in them due to over exposure. When looking up a bit the ground gets very dark and you can see the cloud details. Evem dark incoming clouds look white while the sun is out.
In the alpha and early beta this was not the case.
