Lumen GI and Reflections feedback thread

Hi all, I am new to Unreal and I am getting crazy with an issue for days now.
I’ve used Datasmith to import a scene from 3ds Max.

When I use Lumen everything is fine, once I turn ON Raytracing Shadows or Raytracing GI I get a weird blue result which you can see in the attached image.

I’ve noticed that this is due to the BP_LightStudio element or in general to the Sky Atmosphere Element. What am I doing wrong? Outside of the walls everything is perfect by the way, take a look at the plants for example, inside is a “mess”.

I would like to use the Harware Raytracing as the Lumen ones
are too blurry to me. I’ve tried to use this command:

r.Lumen.Reflections.DownsampleFactor off

But the quality option doesn’t change anything at the end, 200 is the same as 10 or less.
This is why I need the HW raytracing for some future glass elements as well.

The other day worked fine, now it doesn’t.

Any ideas?

This is the Lumen result:

This is the HW Raytracing reflections:

Thanks in advance!
