Step 3 of 7
Install Custom Shaders Patch (CSP)
CSP is a huge upgrade for the game engine: modern lighting, day and night, weather, better performance and Lua apps. Nearly every modern mod expects it.
The short version
- Download it from acstuff.club/patch. Public versions are free; preview versions (with rain) come from the developer's Patreon.
- Extract the zip into your root folder, then restart Content Manager.
- Pick the version Pure asks for, not just the newest one.
Which version?
| Version | Cost | What you get |
|---|---|---|
| Public / recommended | Free | Stable, everything you need to start. |
| Preview | Patreon | Rain and the newest features. Some new mods need it; their page says so. |
Install it
Download the zip
From acstuff.club/patch. It's called
lights-patch-v0.x.x.zip.Extract it into the root folder
Open the zip: you'll see an extension folder and a
dwrite.dll. Copy both into your root folder. Say Yes / Replace when Windows asks about existing files.Restart Content Manager
Close and reopen it so it finds CSP.
Also fine for CSP: drag the zip onto the Content Manager window and confirm. (This shortcut is fine for CSP, but not for Pure or filters.)
Turn it on and check
Go to Settings›Custom Shaders Patch›General patch settings and tick Active at the top.
Updating or going back
Install another version exactly the same way; it replaces the old files. If something breaks after an update, install the version you had before.
