```auto let roofMaterial = new StandardMaterial("roofMaterial"); roofMaterial.diffuseTexture = new Texture("src/assets/roof.jpg", scene); roof.material = roofMaterial; ``` ![屏幕截图 2024-07-29 162259](https://us1.discourse-cdn.com/flex024/uploads/babylonjs/original/3X/4/1/419f3a0d319e3b604f5d1dd9e4c3bd6c4201a779.jpeg) but the texture of the main body of the house is still there, no problem in the webgl environment ---

Possibly related, webgpu does not support rgb texture format: > [@Why doesn't WebGPU tolerate TEXTUREFORMAT\_RGB?](https://forum.babylonjs.com/t/why-doesnt-webgpu-tolerate-textureformat-rgb/46163): > > I am curious as to why the WebGPU engine does not tolerate TEXTUREFORMAT\_RGB. If under the hood , it really needs to follow some RGBA layout , can’t the engine internals handle that conversion? PlayGround: I guess a fix would be to convert to png to get the alpha channel back 🤔 ---

[image] 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… ---
