I’m working on an Archviz project in UE 5.5 to produce some videos. While the overall quality of the images and animations meets my expectations, I am encountering some issues with reflections in mirrors.
As shown in the video, particularly in darker areas, there are blotches and flickering.
I achieved some improvements by increasing the “Reflection Bounce” value in the Post Process Volume from 1 to 2. However, the flickering persists, and further increasing the value does not seem to yield additional benefits.
Do you have any recommendations on which parameters I should adjust to address this issue?
Additionally, is it possible to use Planar Reflection Screen in UE 5.5?
I don’t like this solution because i makeing a game and the performance drops a lot…
but maybe for a architecture project it does not matter…
Anyway in a mirror you will have not a perfect reflection (like a real mirror)
Not if you don’t have a mega-super graphics cart… even so maybe you will have not a perfect reflection.
Real-time rendering has many limitations and reflections are one of them.
Hi @Ivan3z , thanks again for the suggestion.
Yes in this case it’s an architecture project and I wouldn’t mind taking longer time in rendering the frames if in the end the video turns out smooth and without flickering.
I knew the video you linked and I had tried increasing the value of “Final Gather Quality”, but still in the mirrors remain that annoying flickering. Any other ideas?
