Custom GLB

Use Custom GLB to add your own 3D model to a room. A GLB is a single 3D model file that can include its geometry, materials, and textures.

Add a model

1. Open Tools and choose Custom GLB.
2. Paste a direct GLB URL or upload a GLB file.
3. Select Spawn GLB and place the model in the room.
4. Use transform controls to position, rotate, and scale it.
5. Select the placed model to review its GLB Settings, including collision, shadows, size, camera fade, and persistent physics.

Some import flows offer a Draco compatibility choice. It is not an automatic optimization step. Prepare the model carefully and test the actual result in a small area before placing many copies.

Prepare before importing

• Export one self-contained GLB instead of a model that depends on files next to it.
• Apply a sensible scale and orientation in your 3D application.
• Remove hidden geometry and unused materials.
• Use texture sizes that match how close players will get to the object.
• Test collisions and shadows from a player's view.

Example: add a custom landmark

1. Import one landmark GLB near the room entrance.
2. Scale it until it is readable without blocking a path.
3. Walk around it to check collisions and camera visibility.
4. Only then add lighting, text, or interactions around it.

See Assets and Performance for general preparation guidance and Physics Settings when the imported model should react physically in play.
