What are extensions?

Extensions are enhancements to existing track mods in Assetto Corsa.
They consist of an additional 3D layer that add new models like bridges and gantries, brake markers, signs and billboards, buildings, kerbs, vehicles, marshal lights, white lines, etc...
They also include set of configuration files that improve visual quality and add CSP features like grassfx or rainfx, trees, people in stands, animated billboards, environmental effects for example.

Prerequisites

In order to make extensions work, first thing is to install Custom Shaders Patch (CSP) which you will find here:

https://acstuff.ru/patch/

CSP Version must be at least be 0.1.79

You can also install more recent versions (0.1.80 or 0.2.x).
They have some very nice improvements but sometimes can be less stable especially the most recent ones.

How to Download Tracks

First thing to do is to download the original track.

It can be a track from the original Assetto Corsa game and in this case you can skip this step

Or it can be a third-party track mod and in this case links to these track mods are always provided in the related extension post.

You can find almost all the tracks mods provided by the great Assetto Corsa community in the Breathe listing (huge thanks to him!!!)

How to Install Tracks

Once you have the track file (generally a compressed zip or rar archive )
you have to install it either by drag and drop it to Content Manager or
manually install it within Windows Explorer by extracting it to your assettocorsa folder.

In the end, the track folder should be located in the folder

assettocorsa\content\tracks

How to Download Extensions

Extensions link are always provided in the post as google drive links.

They are always accessible so if they don't it can be for two reasons:

• the link has been updated. When it happens (probably due to browser cache), just update the page with Ctrl+F5) and you should get the new link

• the link has been archived. This track extension version is obsolete and a new version is available (probably with a link provided in the post)

How to Install Extensions

If you have some old versions of the extensions, it can be sometimes useful to completely remove and reinstall track and extension folder before installing extensions to avoid conflicts

Once extension is downloaded, you have to install it. Follow one of these two methods:

• Method 1: Drag and Drop (recommended)

• Open Content Manager.

• Drag the downloaded .zip or .rar file directly into the Content Manager window (or use the install from a file menu).

• A green notification will appear in the Content Manager menu at the top right, asking if you'd like to install the layout(s). Click Install.

• Content Manager will automatically extract and place the layout/extension files in the correct directory.

• Restart Content Manager to ensure it recognizes the new layout(s).

• Method 2: Manual Installation (only if drag and drop fails)

Unfortunately, extensions cannot always be installed directly by drag and drop so most of the time you will have to extract them within Windows Explorer.

All extensions archive file respect the tracks folder structure so you just have to extract the track directly to your assettocorsa folder and that's it. It should be something like this:

...\Steam\steamapps\common\assettocorsa\content\tracks

Troubleshooting

.

"Cannot have 0 cars" Error:

This error always indicates incorrect installation of the track and/or extension.
Please read the installation steps again and everything should work perfectly fine 👌

First thing to know is that Content Manager cannot install extensions directly
so you have to manually extract the extension zip file to your assetto corsa folder (and this folder only)
using Windows Explorer (override extension existing files if asked)

To check that your install is OK, here is an example of a correct track/extension folder structure:

.

General Issues:

All tracks extensions are tested (by me obviously and by all users that have already download it before you) so if issues occur they are either detected and corrected quickly or they are caused by something wrong in your CSP config or the track / extension install

In a majority of issues, if you just remove the track folder completely then reinstall it and the extensions, that should solve the issues.

.

Incorrect CSP tracks config folder:

Some issues can also be caused by the way your CSP version loads base extensions files so there are some compatibility issues.
For recent CSP versions make sure your folder [assettocorsa\extension\config\tracks] contains only subfolders and no files.

Also make sure base extension files are automatically downloaded in your CSP settings

.

AI Cars Not Starting Race Issue:

Depending on the track, issues occur with latest CSP versions (> 0.2.x) with AI cars not starting the race

All we can do about it right now is just to go back to an older CSP version and wait for a CSP fix.

Please note that if you restart the session (even immediately after entering the race), everything is OK the second time.

.

AI Spline Issue:

This issue can be caused by some AI file incompatibility with your CSP version

To solve it go to Go to [Settings / Custom Shaders Patch / New AI behavior]
and uncheck the [Extra options for AI splines]

.

No Spectators:

In order to have spectators appear at your track check your config in Content Manager

Go to [Settings / Custom Shaders Patch / Track adjustments / Spectators] and uncheck the [Hide all spectators] and [Adjust amount of spectators] options

.

Lights issues:

Because everyone has different config, different PP Filter, different hardware, different settings, different taste, there is obviously no magic settings for lights.

Most of the time , I try to make lights work for everyone but if this is not the case (and if it's not some issues due to CSP - see above), the most easy way to improve lights to your taste is to adjust your Pure settings in-game, and PP filter brightness settings is always a good way to start:

.

Color issues / Seasons :

If your colors in game are completely desaturated it can be caused by seasons settings

To "solve" this, either set your race date to summer or chose another setting for the seasons in [Settings / Custom Shaders Patch / Track adjustments / Seasons ]
