I tried to give a detailed title for anyone searching for this in the future, since I didn’t find anything too useful myself.
I’m experiencing an issue on my android (Version 7) phone. As soon as the environmental texture is loaded in. Parts of the mesh exposed to spotlights are rendered completely white.
I can fix this by removing the texture and that’s no big deal, as I can just create a low fidelity version of the scene to cater towards this issue. But how do you know when this issue will actually happen? Is it actually the android version? The browser (Chrome 90.0.4430.210) seems up to date and uses WebGL 2.0.
Additionally the metallic texture on PBR Materials block the specular of the spotlight. Here I can also live with removing the texture, but as I said I would like to know when they aren’t supported.
