    Hi,
    I'm Building a WebGL app.
    I'm using URP and Unity 2020.3.8f1.
    When I'm building the project it works great on WebGL 2.0 but the textures are messed up for WebGL 1.0 and I need WebGL 1.0 for Safari.
    Even when I build the example scene that comes with Unity the textures are messed up (Check photos please )
    Any idea how can I fix this ?
    Thanks

    Sorry, I don't have an answer. But if you don't mind me suggesting, I noticed you have posted this twice. Please be mindful of not posting multiple times the same question to keep the forums tidy and help other users find answers to similar questions. Thank you.

    The problem here is that WebGL1 does not support High Quality Lightmap Encoding, which uses Float16 textures. If you're including WebGL1, you should use Normal Lightmap Encoding. You can set this in the Player Settings for WebGL. We've recently added a Player Settings warning for this, and has been backported to previous versions for upcoming releases.

    Thank you so much!! It worked!
    One more question.. The performance in Chrome and Firefox is great but in Safari it is not good and has a low frame rate .. Any idea what is causing this and how can I fix it ?

    Without looking at the project build, I have no way of knowing what would be causing the slow frame rate in Safari. One thing you can try is the Safari Technical Preview release, https://developer.apple.com/safari/technology-preview. This has WebGL2 support in it, and will be released for iOS 15 in the fall, and MacOS at some point in the near future.
