Hi @alvishvishal, sorry to hear you’re having trouble with Lumen. From what I’ve been researching, it seems like mirror reflections in Lumen are a known issue and can be quite tricky depending on how your level is set up. I don’t have a specific solution because the behavior varies a lot depending on your scene’s configuration, but I’ve gathered some useful information that might help you troubleshoot and find a workaround. Hope it helps!

If you have a floating object above a reflective floor there seems to be a secondary reflection of the object, but only if it is in front of a wall. I attached two images (Lit and Reflections view) made in a blank project with the standard settings. The red circled white reflection is what im referring to. If anyone has a solution for this please let me know.

All the resolution changes I make in the project settings change the entire scene except the reflections of the mirror.

Then I’ve tried without using IES and using the default spot light from UE. pretty good, but still looks like screen space reflection. I also tried this console command, r.Lumen.Reflections.ScreenTraces 1 to 0. The screen space effect is completely gone but all the emissive light is completely gone in the shower room.

I have packaged the project and have just uploaded to Google Drive: Please let me know once you have downloaded the file. Please let me know if this works for you. The project has DLSS enabled, i’m not sure if that causes issues should you not have an NVIDIA RTX GPU. Additionally, if you have any tips on sorting out the loading screen I’d be greatful as the project doesnt seem to be loading in the background while my current loading screen plays.
