5.5 Project Convertion to 5.8 broke Planar Reflections?

Hello everyone!
I have decided to upgrade my project from 5.5 to 5.8 due to the new Lumen technology that I really wanted to test out.

However, immediately at start up I see some things that are flat out broken and I have no idea were to start with fixes.
In the screenshot I attached you can see my 5.5 project on the left and the 5.8.1 on the right.
Somehow, the 5.8.1 project is completely ignoring the planar reflection I set up. Both projects have them, global clip plane is also on. However, the reflections in 5.8.1 are not the ones from the planar reflection actor, they are just the “normal” screen space ones and totally messed up.

I deleted the reflection plane actor in both projects and well, the effect is visible right away.
Whilst the 5.5 turns dark, so no reflections, the 5.8.1 stays the same.
I have no idea on how to “reset” the project to make the planar reflections visible again. Does someone know some sort of workaround?

I also copied the 5.5 plane over, made a new scene etc. but nothing helped to make my main menu look the same as it was in 5.5.

Thanks! :slight_smile:
