Creating a 3D model

3D cannot be created in the editor. They have to be created in a 3D modeling software and imported into the editor by placing them in the assets folder.

Using a 3D model

Drag and drop the .glb file from the Assets panel into the Scene panel. this will create a new entity in the scene that references the first scene found in the .glb file.

Viewing .glb contents

Click on the .glb file in the Assets panel to expand it and see all the contents of the file. It will show all the scenes, meshes and materials inside.

Using a mesh only

1. Create a new Renderable component on an existing entity in the Inspector panel.
2. In the Renderable component form, Open the Mesh dropdown and select the mesh from the .glb file. You find the mesh in the list by searching for the name of the mesh or the .glb filename.
3. (Optional) You can also drag and drop a mesh directly from the Assets panel into Mesh dropdown in the Inspector panel to reference it.

Using a material only

1. Create a new Renderable component on an existing entity in the Inspector panel.
2. In the Renderable component form, Open the Material dropdown and select the material from the .glb file. You find the material in the list by searching for the name of the material or the .glb filename.
3. (Optional) You can also drag and drop a material directly from the Assets panel into Material dropdown in the Inspector panel to reference it.
