Unity Engine

Hello,

I see on my iOS App some artifacts with shadows.
I also see the lights through the geometries. It appears as a white bubble as you can see on the first screenshot on the middle of the garage door.

You can try increasing your shadow map resolution, or decreasing the far shadow distance. Looks mostly like the shadow map aliasing you can’t really completely solve.

Thank you!
I will try your solution.

Looks like there is a problem on 2nd UV set. You can custom the lightmap UV or let’s Unity generate 2nd UV for you.

I don’t use second UV… And no lightmap.

Does the artifact appear only when built out?

Yes!
I don’t have a similar effects on my desktop computer.
It’s only appear on my iOS tabs when I built my project…

Try Edit > Graphic Emulation. (In targeted built platform)
Try all the emulations and see if artifact still happen.
Maybe something is not suit with the tabs GPU.

Thank you for your answer.
I will try this solution but I only have two choice :

  • No emulation
  • OpenGL 2.0 emulation
