If you attempted to merge layouts or edit surfaces.ini, you might have deleted the [TOP] section accidentally.
If this is related to the popular Shutoko Revival Project (SRP) beta builds:
If you are comfortable with 3D editing, you can create a dummy “top” node.
If you want, I can: generate MIDI for the motifs, write a short spoken-word sample script, or produce a 32-bar MIDI sketch in D minor at 140 BPM. Which would you like?
The error "track shutorevivalprojectbetamainlayout is missing" usually indicates that you have installed a specific track configuration or layout (often for "No Hesi" traffic servers) without first installing the base map. The "Review": Why this happens
This issue isn't a bug in the mod itself but a common installation oversight. Many players try to join servers that use custom layouts, but since these layouts rely on the core assets found in the main Shutoko Revival Project (SRP) download, they won't load if that base folder is missing or incorrectly named. How to Fix It To get the track working, follow these steps:
Install the Base Map: Download the latest stable version (currently 0.9.1) from the official Shutoko Revival Project website.
Manual Installation (Recommended): Instead of dragging and dropping files into Content Manager (CM), which can fail to place folders correctly, manually extract the content folder from your download and merge it with your assettocorsa/content directory.
Delete Old Versions: If you have an older version of SRP installed, fully delete the shuto_revival_project_beta folder from assettocorsa/content/tracks before installing the new one to prevent file conflicts.
Use 7-Zip: The mod's official Discord and documentation strictly recommend using 7-Zip rather than WinRAR to avoid corrupted extractions. track shutorevivalprojectbetamainlayout is missing top
Check Prerequisites: Ensure you have the Japanese Pack DLC installed, as many SRP cars and layouts require it to function.
If you are trying to join a specific server, use the "Install missing content" button within Content Manager if available, which can sometimes automatically fetch the exact layout needed.
Are you trying to set up traffic for single-player, or are you having trouble joining a specific online server?

The key to resolving a missing feature in a project layout is to methodically go through the possible causes, from simple typos and incorrect references to more complex issues requiring custom implementation or integration of third-party solutions.
Troubleshooting the "track shutorevivalprojectbetamainlayout is missing top" Error in Assetto Corsa
If you are a fan of the Shutoko Revival Project (SRP) in Assetto Corsa, you’ve likely spent hours fine-tuning your Content Manager settings to get the perfect highway run. However, few things are as frustrating as loading into a session only to be met with the error: "track shutorevivalprojectbetamainlayout is missing top."
This specific error usually triggers a crash back to the menu or prevents the map from loading entirely. What Does This Error Mean?
In Assetto Corsa, every track folder requires a specific structure. The "top" refers to a UI element—specifically the top.png file—or a data entry in the track's layout configuration. If you attempted to merge layouts or edit surfaces
When Content Manager or the AC engine searches for the Shutoko Revival Project Beta Main Layout and cannot find the header information ("top"), it assumes the track files are corrupted or incomplete and halts the simulation. Common Causes
Incomplete Extraction: SRP is a massive mod. If you dragged and dropped the .7z or .zip file directly into Content Manager, it may have failed to extract all sub-folders correctly.
Version Mismatch: You might be trying to join a server running an older (or newer) beta version than the one you have installed.
Manual Folder Errors: If you manually moved files into content/tracks, you may have accidentally placed the layout folder inside another folder, breaking the file path.
Missing UI Files: The ui folder within the specific track layout is missing the ui_track.json or the top.png image. How to Fix the "Missing Top" Error
1. Re-install via Manual Extraction (The Most Reliable Method)
Avoid dragging the compressed file into Content Manager. Instead:
Delete your existing shuto_revival_project_beta folder from common/assettocorsa/content/tracks. Open the mod's .7z file using 7-Zip or WinRAR.
Manually drag the track folder into your AC directory. This ensures that every small .png and .json file (including the "top" files) is placed correctly. 2. Check the UI Folder Search your project files for mainlayout (
Navigate to:content/tracks/shuto_revival_project_beta/ui/main_layout/ Check if there is a file named top.png.
If the ui folder is empty or missing, Content Manager won't know how to display the track, leading to the "missing top" crash. If it’s missing, a re-download of the mod is necessary. 3. Update Content Manager and CSP
The Shutoko Revival Project heavily relies on Custom Shaders Patch (CSP). Open Content Manager > Settings > Custom Shaders Patch.
Ensure you are running a "Recommended" or "Latest" version (typically 0.1.79 or higher). Older versions of CSP sometimes struggle to parse the complex layout structures of SRP Beta. 4. Verify Server Requirements
If this error only happens when joining a specific online server, the server might be using a custom "PTB" (Public Test Build) version of the layout. Check the server's Discord or description link to ensure you aren't using the standard Public Beta when the server requires a specific layout tweak.
The "track shutorevivalprojectbetamainlayout is missing top" error is almost always a file path or extraction issue. By deleting the old folder and manually extracting the mod using a dedicated file archiver, you ensure that the UI elements required by the game engine are present and accounted for.
Have you checked if your Custom Shaders Patch is up to date, or are you running an older version of the SRP track?
In many game engines (Unity, Godot, custom HTML/CSS/JS frameworks for racing games), mainlayout is a container for UI elements like speedometer, timer, position rank, etc.
The "missing top" could mean:
Search your project files for mainlayout (.xml, .unity, .tscn, .json, .uiskin, etc.).
Example in Unity:
Assets/UI/MainLayout.prefab
Assets/Scenes/TrackScene.unity
To understand the error, break it down:
In simpler terms: the game engine is looking for an object called top inside the track’s layout configuration, but cannot find it. This breaks the loading sequence.
