[UE5] Strange tile on materials

Hi,
I have a problem with my scene. All materials in the scene has a strange mosaic. Regardless of the complexity of the material.
In the viewport, this problem is barely noticeable, but when rendering it is very.
Perhaps someone faced such a glitch before?
UE5
Global: Lumen
Reflect: Lumen

Might be a mohair effect. Make sure your textures are a power of 2. like 1024x1024, 2048x2048 etc. This will improve it but mohair effects are difficult to completely eliminate in Unreal.

I checked all the textures but unfortunately it didn’t work. The problem was solved - I changed the type of skylight to cubemap and added HDR map.

Thanks S-Dot
