Bit of an issue with your CSP settings...
If I use your SKYMAX settings, Sol transitions beautifully from weather to weather, and you can see the clouds move across the sky when this happens - never used to happen before, so that's cool!
However, everything is milky with no depth to the shadows at all.
My settings:
Your CSP settings:
Another thing to mention - when I use your CSP settings, I can't change anything in the Sol Config app in-game. The quality is down to 60%, and nothing makes a difference. If I use my own CSP settings I can change everything in-game, but Sol doesn't update beautifully when transitioning from weather to weather. The clouds also look different...
Very weird. Any ideas?
EDIT: Found it.
IMPLEMENTATION=pure
Removing that, I'm getting proper visuals once again. The only thing is, I've never installed Pure so perhaps it's conflicting. Either way, removing that line in the CSP setting under WeatherFX worked a charm.
Perhaps make two versions, one for Sol and another for Pure?
