Texture turns gritty/grainy?? Reflection Noise!!

Hi!

I’m working on my Project, and when I open the Export or Standalone game, my floor texture turns gritty or grainy (I don’t know the right word for it).
When I play the Viewport game, everything is fine!
How can I get rid of that grainy effect?
I’m working in 4.13!

Greetings, !

This is the Export/Standalone ↑

And this is the Viewport game ↓

Try putting a reflection capture in there, maybe that fixes it.

there are at least 3 reflectioncaptures right there… strange

I think I fixed the problem! It was the Misc and SSR in the PostProcessVolume… I tried to play around with those settings… the Max Roughness was the problem I think, and also a few settings of the specular and roughness in the Material of my WoodFloor.
