I abSOLutely love it. As a sort of newbie to the sim racing thing I wanted to make AS a bit more, well pleasent to look at. I was surprised by how straight forward Sol is to use, to me its very 'matter of fact' and only says what is needed, something I like in apps.
I did struggle - by my own doing - with the skybox being 'blank' which took me some time to work out, it was the CSP being out of date, I opted to one Sol told me to use in game and bing! a pretty blue sky over France. I am yet to try out the weather functions, I plan to spend the entirety of tomorrow fine tuning Sol to my liking. So far I am over the moon with it, I just regret not getting it sooner.
Big thank you to Peter Boese for creating it, what a guy!
