Hi there!
Back in UE 5.3 I made the infinity mirror box using the deprecated Standalone Raytraced Reflection Method and a post process volume and it worked just fine.
Here’s the modified rendering project settings and the result.
The model is a box with two planes, one at the top and one at the bottom, which have a simple mirror material and their normals are facing each other, so that you can see the infinite reflections from the outside of the box.
Now, in UE 5.4 I managed to recreate the same effect using Lumen, but it appears to work only when I’m within the two planes, once I’m outside of the box it doesn’t work anymore.
It seems like the top plane affects the raytraced reflections, even though I should see through it.
Unfortunately going back to 5.3 is not and option. Any ideas on how to fix this?
Thank you!
