# How to Install Sol & Pure Weather System in Assetto Corsa

> Bring 24-hour cycles and dynamic weather to your Assetto Corsa server. Learn how to synchronize lighting, time, and cloud patterns for all connected drivers.

## Day/Night Cycles & Weather

By default, the vanilla Assetto Corsa engine is limited to static skyboxes and fixed lighting states. Installing the **Sol** or **Pure** weather systems on your server unlocks a full 24-hour time progression, realistic star maps, and localized weather states. These systems ensure that every driver on your server sees the exact same lighting and weather conditions, which is important for competitive immersion.

## Server-Side Configuration

While the high-fidelity visual effects are rendered locally on each player's PC, the server acts as the primary orchestrator for time and weather synchronization.

<Steps>
  <Step title="Upload Weather Assets">
    Using the [Game Panel](https://panel.freakhosting.com) File Manager or SFTP, upload your weather script folders (e.g., `sol` or `pure`) into the `/content/weather/` directory on your server.
  </Step>

  <Step title="Configure Time of Day">
    In your `server_cfg.ini`, define the starting conditions:

    * **TIME\_OF\_DAY:** Set the initial hour (e.g., `1400` for 2:00 PM).
    * **SUN\_ANGLE:** Adjust the position of the sun relative to the horizon.
  </Step>

  <Step title="Initialize the Script">
    Set the `WEATHER` variable in your configuration to point to the exact folder name you uploaded in Step 1.
  </Step>
</Steps>

## Pure & CSP Integration

If you are transitioning to the modern **Pure** system (the successor to Sol), you must ensure your server is prepared for advanced cloud synchronization.

<Tabs>
  <Tab title="Cloud Sync">
    Open your `extra_cfg.yml` (available when using the Content Manager server wrapper). Ensure that CSP features are allowed so the server can broadcast high-resolution cloud data to connected clients.
  </Tab>

  <Tab title="Time Multiplier">
    You can speed up the passage of time by adjusting the `TIME_MULTIPLIER` in your config. This allows you to experience a full 24-hour cycle during a 1-hour race session.
  </Tab>
</Tabs>

<Important>
  ### Networked Consistency

  If the weather script on the server does not match the script active on the player's client, they may experience "flickering" lighting or mismatched shadow directions. Always communicate the required weather engine to your community members.
