I do see the same thing than @RaananW on my side (Chrome 120.0.6099.218 (Official Build) (64-bit)).

@jackny Are you sure WebGPU is in the list of supported engines in the Playground?

It already happened to me that after an update, my Chrome did not support WebGPU anymore (until the next update)…

Regarding the black roof, it’s because there’s an error when reading `roof.jpg`. You can display the error by adding an observer to `BABYLON.Texture.OnTextureLoadErrorObservable`:

It seems the `roof.jpg` file is invalid in some way (maybe the header?): just opening and resaving it in [Paint.net](http://Paint.net) makes it work…
