Hello everyone!

I have a GLTF file with a lot of textures distributed on a large scene: while the user explores the scene, the memory load goes up because new textures are loaded in memory, but old ones aren’t disposed of.

I’d like to call `.dispose()` on textures that are not visible on the scene, but I don’t have a direct reference to them, since they are managed by the GLTFloader. How can I dispose them, without having to use a custom loader?

Thanks!

Disposal of textures only works if you call `.dispose()` on a texture object. Have you tried to traverse through the `glTF` scene that is returned by the loader? Something like:

```auto
loader.load( 'model.gltf', function ( gltf ) {

    gltf.scene.traverse( function ( child ) {

        if ( child.material ) {

            // do something with child.material
						
       }

    } );

    scene.add( gltf.scene );

}

```

In this way you can create a map/set of all textures in the scene and dispose them if necessary.

You set material opacity = 0

That does not dispose a texture…

Thanks! I already keep track of the children, I haven’t tough about using `child.material.map.dispose()`, that was easy, I just needed to add some logic for checking visibility of the texture 🙂

Thank you very much!
