Texture and Rendering Quality Issue on iOS

Hi Unity Community,

I’m encountering an issue with the visual quality of my game when building for iOS. Specifically, the Terrain texture in one of my levels is problematic. What should look like sand ends up appearing like a mirror instead.

Here’s a comparison of the textures:

Interestingly, the quality returns to normal if I view the character from above.

What I’ve Tried So Far (None Worked):

  1. Set project quality to Ultra for iOS.
  2. Adjusted project graphic settings for iOS to mimic PC settings.
  3. Changed the sand texture and overridden iOS texture settings.
  4. Tweaked the post-process layer (no improvement).
  5. Modified camera settings (no improvement).
  6. Adjusted directional light settings (no improvement).
  7. Changed environment settings, including fog settings (still no luck).

Does anyone have an idea what could be causing this problem or how I can fix it?

Thanks in advance!

Regards,
Hamdan
