Ich habe erfolgreich eine .dae-Szene über ColladaLoader importiert.

Das Problem ist, ich muss zwischen mehreren .dae-Dateien wechseln.

Ich kann die dispose-Methode anscheinend nicht richtig implementieren.

        dae.traverse(function(obj) {

            console.log('unloading ' + obj.id);

            scene.remove(obj);

            if(obj.geometry)
                obj.geometry.dispose();
            if(obj.material)
                obj.material.dispose();
            if(obj.mesh)
                obj.mesh.dispose();
            if(obj.texture)
                obj.texture.dispose();

        });

        scene.remove(dae);

Was könnte ich möglicherweise falsch machen?

ielen Dank im Vorau
