# Billboard

### Type
pre-defined

### 3D
The Billboard is a 4m x 2,25m opaque Plane.
Its Origin is at the Bottom-Center.
Spawnpoint should be {0,1,0} so its 1m above the floor.

### Custom Args:
| Key | Type | Implemented | Description |
|---|---|---|---|
| url | string | ✔️ | Storage path within `user_files` bucket (e.g. `uuid/image.png`). A signed URL is generated at runtime. |
| grabable | `"true"` / `"false"` | ⚠️ (Unity missing) | Whether the item can be grabbed in-experience (common to all types) |

### Special Notes:
The Creator handles image uploads and assigns the storage path to `url`.
The `url` value is a Supabase storage path, **not** a full URL — the runtime calls `CreateSignedUrl` to fetch the actual image.

### Example:
