Massive reflection noise

I am experiencing very bad reflection artifacts and noise. I couldn’t find a solution. Tried UE4, UE5 and it’s still the same
Reflection behaves like stripes when reflecting a tree. Or it gets really noisy in easy reflections like a wall getting reflected.
Thanks in advance!

Thats because limitation of screen space refection, with it only things on screen can be reflected. you can read it here, you might want to use diffrent reflection types:

Also Lumen reflection in UE5 is known to be broken right now it’s work in progress.

Thanks I checked it out and tried using planar reflections and glass material. It worked, but I only can make one plane at a time, which is not very useful for realtime. I am trying now in UE5 with lumen, looking to make it usable for more than one reflections.
