MoreRVers - Multiplayer Expansion Mod for RV There Yet?

A runtime mod that increases the multiplayer player cap beyond the default 4-player limit for RV There Yet.

Only the host needs to install the mod.

Overview

This mod patches the game's multiplayer cap at runtime, allowing you to host sessions with more than the default 4 players. The modification uses UE4SS for runtime patching without requiring binary editing or permanent game file changes.

Features

• Simple Configuration - Single-value INI file configuration
• Host-Only Requirement - Clients do not require mod installation
• Non-Destructive - No permanent game file modifications
• Flexible Limits - Configurable player count from 1-24
• Runtime Patching - Applied immediately upon session creation

Installation

Two installation packages are available with each release. The With-UE4SS package is recommended for most users.

Option 1: With-UE4SS (Recommended - Easy Install)

File: MoreRVers-vX.Y.Z-WithUE4SS.zip

This package includes UE4SS experimental and MoreRVers pre-configured. Just extract and play!

1. Download MoreRVers-vX.Y.Z-WithUE4SS.zip from the latest release
2. Navigate to your game directory:

   <Steam>\steamapps\common\Ride\Ride\Binaries\Win64\
   

3. Extract all files from the zip directly into the Win64 folder
4. (Optional) Configure player limit by editing ue4ss\Mods\MoreRVers\config.ini:

   MaxPlayers = 8

5. Launch the game and host a session

That's it! The mod is pre-enabled!

Option 2: Mod-Only (Advanced Users)

File: MoreRVers-vX.Y.Z-ModOnly.zip

Use this if you already have UE4SS experimental installed and configured.

Requirements:

• UE4SS experimental branch (3.0.1+)
• RV There Yet? (Steam version)

Installation:

1. Download MoreRVers-vX.Y.Z-ModOnly.zip from the latest release
2. Extract the MoreRVers folder to:

   <Steam>\steamapps\common\Ride\Ride\Binaries\Win64\ue4ss\Mods\
   

3. The mod ships with an enabled.txt marker file, so UE4SS picks it up with no further setup. If your UE4SS build ignores that, enable it explicitly by editing ue4ss\Mods\mods.txt:

   MoreRVers : 1
   

   Note: Add this line before Keybinds : 1
4. Configure the player limit in ue4ss\Mods\MoreRVers\config.ini:

   MaxPlayers = 8

5. Launch the game and host a session

File Tree

When properly installed, your game directory should look similar to this:

{Steam}\steamapps\common\Ride\
├── Ride\
│   └── Binaries\
│       └── Win64\
│           ├── Ride-Win64-Shipping.exe         
│           ├── dwmapi.dll

Configuration

Edit ue4ss\Mods\MoreRVers\config.ini:

MaxPlayers = 8

Configuration Parameters:

• Default: 8 (vanilla game limit is 4)
• Range: 1-24
• Recommended: 8 for optimal stability

The game must be restarted for configuration changes to take effect.

Advanced options

These are only worth touching while troubleshooting:

Key	Default	Purpose
LogLevel	INFO	DEBUG makes the mod log every object and property it inspects. Set this before reporting a bug.
ReapplySeconds	10	How often the cap is re-applied. The game can overwrite the cap after the mod sets it; set to 0 to disable.
HardUpperLimit	24	MaxPlayers is clamped to this.
SanityCeiling	64	The mod only overwrites cap-like values at or below this, so it can never clobber an unrelated number.
WatchActorSpawns	1	Checks each spawned actor for being a GameSession. Set to 0 if you suspect a performance cost.

Verification

In game, press F10. The mod prints a diagnostics report: its version, the target cap, which hooks it managed to install, and every player-cap property it can currently see, with its live value. If the UE4SS console is enabled you can also type morervers there for the same report.

The report goes to the UE4SS console and to UE4SS.log, which sits next to UE4SS.dll in the ue4ss folder. That file is what to attach to a bug report.

On a working install the log contains lines like:

[21:04:11] [MoreRVers] [INFO] MoreRVers v1.1.0 loading. Target cap=8 (hard max 24). Engine: UE 5.5
[21:04:11] [MoreRVers] [INFO] BP_RideGameSession_C.MaxPlayers: 4 -> 8 (new GameSession)

Troubleshooting

After a game update, start here

A game patch can change the engine build, which stops UE4SS itself from loading. When that happens no mod runs and UE4SS.log will not contain any [MoreRVers] lines at all.

1. Check whether UE4SS.log exists and has recent entries. If it does not, UE4SS never attached: update to the latest UE4SS experimental build and re-install.
2. If the log contains Failed to find EngineVersion, set the engine version manually in UE4SS-settings.ini:

   [EngineVersionOverride]
   MajorVersion = 5
   MinorVersion = 5

   Use the version the game's launcher or Ride-Win64-Shipping.exe reports.
3. If the log does contain [MoreRVers] lines, the mod is loading and the problem is the cap itself. Press F10 while hosting and read the report.

Mod fails to load

• Check UE4SS.log for error messages
• Verify UE4SS 3.0.1 or higher is installed
• Confirm the file structure matches the documented structure
• Confirm ue4ss\Mods\MoreRVers\enabled.txt exists, or that the mod is listed in mods.txt / mods.json

Player limit remains at 4

Press F10 and read the diagnostics report.

• "Active triggers: NONE" - UE4SS loaded but does not expose the Lua API the mod expects. Update UE4SS.
• "No cap-like properties found" - either no session exists yet (host a game first, then press F10), or the game moved the cap somewhere the mod does not look. Set LogLevel = DEBUG, reproduce, and open an issue with the log.
• The report lists a property still sitting at 4 - the write is being rejected or the game is overwriting it. Attach the report to an issue.
• Sanity-check the mod is doing anything at all by setting MaxPlayers = 1. If you can no longer host anyone, the override works and the remaining limit is elsewhere.

Game crashes or instability

• Reduce the configured player count
• Verify UE4SS version compatibility
• Report issues with the complete UE4SS.log

Development

tools/ue4ss_stub_test.lua stubs the UE4SS Lua globals so main.lua can be exercised without launching the game. Run it from the repo root:

lua5.4 tools/ue4ss_stub_test.lua

It is also run by the release workflow before packaging.
