Install Loom

Loom ships as a Unity package tarball. The matching UI packages are bundled inside the Unity package, so you do not need to fetch Loom packages from a public npm registry.

Before you start

Make sure your project matches Supported platforms:

• Unity 6 (6000.3 or newer)
• URP
• Node.js 20+
• macOS Apple Silicon or Windows x64

Add the Unity package

1. Copy the tarball. Copy onl.snack.loom-X.Y.Z.tgz into your project’s Packages/ directory.

2. Reference it. Add the package to Packages/manifest.json:

   {
     "dependencies": {
       "onl.snack.loom": "file:onl.snack.loom-X.Y.Z.tgz"
       // ... your other dependencies
     }
   }

3. Restart Unity.

Verify the install

Run:

Loom -> Doctor

Fix any red checks before continuing.
