iOS build Lightmap looks broken.

Unity Engine
1

Hi there,

I have a Subtractive Baked Lightmap set up for my scenes.

  1. Android build active - it looks fine and doesnt have any dots on surfaces

  2. iOS build all the surfaces are covered with some dots:

824Ă—556 401 KB

I have URP and those settings:

934Ă—933 87.2 KB

What can cause such a graphical artifact on iOS? Any ideas?

Might be the compression used on iOS. You can verify that by disabling “Compress Lightmaps”, although a 4K lightmap size is quite large, you may want to reduce that.
If it’s the compression, you can select the lightmap and set a specific compression scheme for the lightmaps on iOS.
