    I posted something similar earlier, but now I made a test with a scene from scratch.
    This is the standard shader on a standard sphere in a standard scene.
    The higher the smoothness values, the worse the specular effect looks, you start to see polygons in a strange way. This does not happen on PC/MacOS.
    Is this a known problem with the standard shader? Is there a way to avoid it and get a nice highlight? My car shows up ugly because of this.

    Another example comparing specular highlights on iOS with the editor on a car model:

    Sorry, I'm not expert in mobile field. PBR lighting is part of Unity's pipeline and I don't touch it in my assets. What I do is to build additional features on the top of it (UBER features built on the top of Unity standard shader).

    To help you might ask on Alloy thread or Marmoset - esp. Marmoset has shaders that could work better on mobile than Unity standard shader.

    @JelmerV I have the same issue :(
    Maybe this is because of "Unity ARKit Plugin" settings?
    Did you found solution?

    Seems Unity has a bug on Specular lighting at least on iOS platform.
