Static trees flickering or some kind of noise (I don't know) Video added.

Hello Unreal friends,

I am seeking for a help. Tried a lot of suggestions from this forum. But no success.
So I am trying to create a level for a game where there is a small amount of trees. The trees are made in Blender. The trees are created with geometry nodes and so on. I tried not to make heavy one’s. Well, I think. It is about ~100k all in all.

The problem is that, when I entering the play mode in UE viewport it causes trees to flicker
(or flicker-noise don’t know how to describe) even if they are static (have no leaf, have no double geometry).

Maybe some of you experienced same problems. Would like to know the cause.

My specs:
R9 5900x
RTX 3080
16 GB RAM

Anti-aliasing is - TSR

I am adding video to this question. Maybe it will be more informative.
I will upload necessary info here if needed.

Thank you all, who answers to this. :slight_smile:
