A BepInEx 6 (IL2CPP) plugin that points the Rec Room client at a self-hosted / private "CannedNet" server instead of the official Rec Room backend.

It does this entirely client-side with Harmony patches — no game files are modified on disk. The plugin rewrites the RecNet name-server lookups, swaps in your own Photon credentials, and disables the client-side guards (EasyAntiCheat, TLS certificate pinning) that would otherwise reject a non-official server.

⚠️ For private/experimental servers only. This redirects traffic away from official Rec Room infrastructure and disables anti-cheat and certificate validation on the client. Do not use it against rec.net or any service you don't control. Use at your own risk.

What it does

Patch	File	Effect
Name-server redirect	`Patches/SendRequestPatch.cs`	Intercepts `BestHTTP` requests and rewrites the host `ns.rec.net` → your configured server. Also provides optional HTTP request/response logging.
Photon override	`Patches/PhotonPatches.cs`	Replaces the Realtime / Voice / Chat App IDs (and optionally the Photon name server + port) with your own.
EAC bypass	`Patches/EACPatches.cs`	Forces EasyAntiCheat "ready" and stubs the challenge-response so the client connects without the official anti-cheat.
TLS bypass	`Patches/FuckOffTLS.cs`	Skips server-certificate validation so a custom server's cert is accepted.
Promise stub	`Patches/PromisePatch.cs`	Allows custom global-metadata.dat files without the game crashing.
CheatManager handling	`Plugin.cs`	Deactivates the in-game `CheatManager` (which would otherwise boot you from rooms) while keeping it resolvable for account creation / login.

Requirements

A Rec Room install set up with BepInEx 6 (IL2CPP, bleeding-edge), launched at least once so the IL2CPP interop assemblies have been generated under BepInEx/interop/.
.NET 6 SDK to build the plugin.
Your own server endpoints: a RecNet name server, and Photon App IDs.

Building

The project references the game's interop DLLs, so the build needs to know where your Rec Room install lives. It is not hardcoded in the repo. Set GamePath using any one of:

A local props file (recommended):
```
cp GamePath.props.example GamePath.props
```
then edit GamePath in GamePath.props to point at your Rec Room install root. This file is local-only and stays out of the repo.

An environment variable:

set RECROOM_PATH=C:\Path\To\RecRoom        # cmd
$env:RECROOM_PATH = "C:\Path\To\RecRoom"   # PowerShell

On the command line:

dotnet build -p:GamePath="C:\Path\To\RecRoom"

Then build:

dotnet build

The build validates that GamePath is set and that $(GamePath)\BepInEx\interop exists, and fails with a clear message otherwise.

Installing

A post-build step (the DeployPlugin target in the .csproj) automatically copies the built CannedNet.Client.dll into your Rec Room install's BepInEx/plugins/ folder after every build. Since GamePath already points at your install, you don't need to copy anything by hand — just dotnet build and launch the game.

If you need the DLL elsewhere, it's also left in bin/Debug/net6.0/.

Configuration

On first run the plugin generates a config file at BepInEx/config/lapis.cannednet.client.cfg. Edit it (or use a BepInEx config manager) to set:

[Server]

RecNet NameServer Host — base URL of your RecNet name server (default https://ns.lapis.codes).

[Photon]

App Id Realtime — Photon Realtime App ID.
App Id Voice — Photon Voice App ID.
App Id Chat — Photon Chat App ID.

[Advanced]

Enabled Advanced Settings — must be true to apply the custom Photon name server / port below.
Photon NameServer — custom Photon name server host.
Photon NameServer Port — custom port (0 uses the default, 4533).
Debug — verbose HTTP request/response logging.

⚠️ Debug logs include sensitive data (passwords, auth tokens). Be careful when sharing them.

Project layout

Path	Purpose
`Plugin.cs`	Plugin entry point, config bindings, Harmony bootstrap
`Patches/`	Harmony patches (networking, EAC, TLS, Photon)
`CannedNet.Client.csproj`	Build config + interop references (driven by `GamePath`), and the `DeployPlugin` post-build copy
`GamePath.props.example`	Template for your local `GamePath.props`
