Hey everyone, in Unigine 2.9 the clouds seem to be removed, when the max visibility range for the haze/fog effect gets relatively low (due to the camera far plane decreasing as well?). Because of that, the sun appears more bright at low visibility, even though the cloud density might be set to the maximum. It essentially ignores the cloud settings entirely at low visibility. Even when setting the texture intensity of the sun to 0, a spot bright spot in the sky remains at where the sun should be. I tried to look into the environment.frag shader and played with the mie LUTs (though I do not understand how exactly it works) in the environment presets, but nothing lead a proper solution. I am pretty sure it is related to the mie scattering in some way though. Below I took some screenshots to illustrate the issue. All screenshots were taken from the same camera position and the sun texture intensity of all environments was set to 0. Note that screenshot 2 and 3 look exactly the same, as the clouds seem to have disappeared. If it was working correctly, screenshot 2 should look like screenshot 1. Does anyone have an idea on how to fix this? Please let me know if more information is required to solve this. Thanks a lot in advance!
