Strange behavior when using Raytracing Shadows and GI

Development Getting Started & Setup
1

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?

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

Any ideas?

Thanks in advance!

And this is the correct Lumen result.

As you can see in the first image, the exterior elements are fine but the interior ones not, can’t understand what I am doing wrong…

This is truly bizarre. I’m not entirely sure of the issue, but I’ve noticed similar things in the past. Sorry I don’t have any advice.

We’ll try to find someone to take a look :slight_smile:

Sorry for bothering you, does anyone can help on this issue? I am blocked with the production as I can’t find the solution to it… Thanks in advance!
