Unsigned short indices are supported but still experimental about gdx-gltf

[mgsx-dev]

@waverider404 maybe you didn't configure num bones properly, see #6
BTW, it would be nice to create another issue next time. Since it may be not related to unsigned short indices.

indeed, model cache is not compatible with more than 32k vertices for now. I'm working on a libgdx PR : libgdx/libgdx#5925 which will fix it once merged.

For now, you should either keep max 32k vertices or don't use model cache.

I could add a compatible mesh cache in this repository if my PR get rejected or delayed, so we can let this issue opened until then.

This message is just a warning.

I'm able to load your file with the demo/viewer :

@waverider404 Could you please give more information: What's your issue precisely? any stacktrace or relevent error message? which platform? which gdx-gltf version?

Sorry I just received the message, I am using the gltf-master-SNAPSHOT

Here is my code
`

@Override
public void create() {

	Bullet.init();
	btCollisionObject groundObject = new btCollisionObject();

	CharSequence str = groundObject.toString();
	System.out.println(str);

	environment = new Environment();
	environment.set(new ColorAttribute(ColorAttribute.AmbientLight, 0.4f, 0.4f, 0.4f, 1f));
	environment.add(new DirectionalLight().set(0.8f, 0.8f, 0.8f, -1f, -0.8f, -0.2f));

	modelBatch = new ModelBatch();

	cam = new PerspectiveCamera(67, Gdx.graphics.getWidth(), Gdx.graphics.getHeight());
	cam.position.set(10f, 10f, 10f);
	cam.lookAt(0,0,0);
	cam.near = 1f;
	cam.far = 300f;
	cam.update();

	SceneAsset model_asset = new GLBLoader().load(Gdx.files.internal("grass.glb"));
 	double range = 80;
	int count = 300*10;

	for (int index = 0; index < count; index++) {
		double x = (range / 2) - (Math.random() * range);
		double z = (range / 2) - (Math.random() * range);
		this.instance = new ModelInstance(model_asset.scene);
		this.instance.transform.setTranslation((float) x, 1.0f, (float) z);
		this.instance.transform.scale(8.5f, 8.5f, 8.5f);
		this.trees.add(this.instance);
	}
	

	Texture texture = new Texture(Gdx.files.internal("badlogic.jpg"));


	SceneAsset room_asset = new GLBLoader().load(Gdx.files.internal("room.glb"));

	
	 ModelBuilder modelBuilder = new ModelBuilder();
        model = modelBuilder.createBox(5f, 5f, 5f, 
            new Material(TextureAttribute.createDiffuse(texture)),
            Usage.Position | Usage.Normal | Usage.TextureCoordinates);
        ModelInstance boxInstance = new ModelInstance(room_asset.scene);
        
        this.trees.add(boxInstance);
	
	treeCache = new ModelCache();

that will be awesome!!

Skinned model looks distorted when I animate them :(

libgdx/libgdx#5925 has been merged, it's now possible to use ModelCache with libgdx 1.9.11-SNAPSHOT.
