Changes to Indirect Light in Lumen Scene (Lumen Overview) in 5.1

Hi all! This is my first post on this forum.

It feels like I’m missing something, but the Lumen Scene and Reflection View are not displaying correctly since upgrading to Unreal Engine 5.1 (Version 5.1.0-23058290). I see the effect of direct lights only, not the Global Illumination of these and of other lights in the scene. I tested this in both Nanite and regular meshes.

The contribution of the skylight is not being displayed either. I wonder if that is a bug or if I’m missing a new toggle or switch in the editor preferences or post-processing volume. The surface cache seems to display fine.

Ok, I found out that the problem started when I enabled the Strata Materials. Disabling them in the project settings brought back the Lumen Scene and Reflection visualization to its previous working version.
