Hello, I was wondering if someone could help me figure out this issue when doing virtual production in Unreal Engine. I noticed that when compositing my background with media plate and other CG comp elements, using screen capture component, the output scene of the comp is different than the one I’m seeing in the virtual camera. It’s darker and the bounce/indirect lights are missing, as well as the reflections.
I though at first that I was maybe using a wrong color space but now I assume it has something to do with the post process material applied to the composure layers and the way Unreal handles post process for screen captures vs the camera view.
Does anyone have a solution for this or could explain to me why it works this way and if it can be even fixed?
Thanks in advance for your help!

I can see the difference after doing a very basic composure layer with the Unreal VP example scene. The Camera view and Comp are different from the very beginning when the comp is created (screen captured). I don’t know if it has to do something with the post process material applied to the comp or if there is a setting that I am missing.
UPDATE:
I came across a post that mentioned turning on Hardware Ray Tracing and Shadows. This did get me closer to the lights and reflections I want but there is an insane amount of flickering in the scene that I don’t know how to get rid of.
Yes, it flickers only once I set up comp layers and assign the CineCamera capture to the background layer, that’s when the shading changes and flickering starts, even if Lumen is enabled.
At first, there are no reflections and the colors and lights feel flat in the comp layer, and when I enable “Capture Every Frame” in the Scene Capture Component, the lighting gets closer to the scene as if Lumen starts working only then, I also get the reflections somewhat correct. But that setting causes the flickering.
The UE scene itself and also the CineCamera view are okay.
