Yeah, this is due to the async nature of scene creation in the demo.

In the last lines of the html file you downloaded, you can find those lines:

```auto
scene = createScene();
        
        

        engine.runRenderLoop(function () {
            if (scene) {
                scene.render();
            }
        });

        // Resize
        window.addEventListener("resize", function () {
            engine.resize();
        });

```

change that to:

```auto
createScene().then((scene) => {
        engine.runRenderLoop(function () {
            if (scene) {
                scene.render();
            }
        });

        // Resize
        window.addEventListener("resize", function () {
            engine.resize();
        });
})

```

This should work.

You can read about async await and maybe implement it a bit better if you want 🙂
