Hello,
Here’s my problem. I have integrated a led screen on my stage, but I have a rendering problem with lumen, the reflections don’t load quickly enough and when there are strobes or fast videos the reflections are super slow (video attached). In scalability i set Shadows, GI & Reflection to “High”.
The video signal comes from a Blackmagic capture card, I have the same problem with NDI…

Maybe Lumen isn’t made for this idk ? I’m still new to unreal

Do you have any ideas?

Lumen won’t be able to solve your use case, I believe I offered a solution in another response to one of your posts?
