Please notice !!!
Sol does not bring rain into AC.
CSP is doing this. Actually rainFX is in development.
RainFX previews are available at Ilja Jusupov's Patreon account.
Sol 2.1 has an advanced control of rainFX already integrated...
For more information, maybe you like to watch this

DO NOT set a higher value than "Two faces per frame" in reflections frequency:

Also lower the resolution to 1024x1024. There is no big difference visually, but it gains much more fps...
For those weather effects, you need to set the cloud's render method to 2 in Sol Config app. Then the advanced skysim weather code is running.
Your track textures are not looking like they should look.

Its actually not an error, its a feature, called "seasonal adjustments". With CSP it is possible to change the track's textures to other colors. There is a problem with CSP versions between 1.30 and 1.38, so the textures looks much darker than they should look. This is fixed with CSP version 1.39.
CM just uses the current date for the race session. If its wintertime where the track is located, textures will be changed to look like they have a snow cover.
Change the date to summertimes
In CM's Drive menu:

or directly in game:
Open the Sol_weather app and change the date:
The default Sol filter. You can change all Sol parameters. This filter has a static exposure, which is adapted for daytimes. The filter has a neutral color balance.

The filter tries to have an optimal exposure for all situations. It uses a custom Autoexposure. CSP’s emissive and bounced lights are dynamically optimized for day and night light.The filter also adapts the color balance for different light situations.

A clone of __Sol_Extra. This filter works with the Reinhard tone mapping. The goal is to have less contrast in mid and high tones.

A filter for very bright monitors. It uses SDR dynamic and emulates some HDR effects.

This filter represents the colors with an accuracy of 98%, if a sunangle of 45° is used. It uses the linear tone mapping to achieve this accuracy. Therefore, bright colors will clip.

This filter uses sensitometric tone mapping. I realized a proper gamma to be color-neutral for a wide range. In high tones (>220) it will compress, this prevents clipping.
You can customize Sol ingame with the Sol_config app:
Please install Sol manually, as it is described in the guide!


Sol is a weather simulation system for Assetto Corsa/Shader Patch

i made the switch back to pc about a year ago. i've tried all games and AC is the one i like most. once i started googling racing at night on AC i found this mod. but it's so much more. whenever i can i'll donate. i don't like the way the game looks without sol . i hope they contact you for ac 2.0

This brings Assetto Corsa to a higher level, conjugated with rain fx, it gives AC the best weather available in 2021. This is genius work.

Very good, everything is perfect the graphics are incredible, but I got one question.. When sol 2.1 came out I no longer can change the "Nerd CSP Settings" it just simply doesn't change anything visually and some cars tail lights are just not enough and I want to increase it but cant any help?

Why don't you ask before you rate? There is a discussion section, where problems can be solved. It would be so easy. But rating and then forcing the creators to solve the problem is anoying...

Something is incompatible with your system or user name. In the install guide there is a chapter "win 7 usage". Use this solution and first try to put the link to your documents folder in the file. If this is not working, use a folder which is not in your user's folder...
