Hi,
It's not about the AI line, because I just do hotlaping but, I got a problem that I resolved myself, so It may help for somebody else.
As a non user of "PURE" and/or "SOL", without any layer but CSP, the track seemed always with a weird mood, with the lighting like I am very early in the morning. Meanwhile I'm at 12.00 PM with a clear weather.
So, I resolved it by deleting in the ext_cong.ini file the lines about [SOL] in the extension folder of the track and deleting the lighting.ini file in the "Data" folder.
Cheers
