However, when I made the light go slower, 1 unit every tick, the noise artifacts were almost gone. First, I made the light move pretty fast (10 units every tick) and that caused a lot of horrible artifacts as the light moved away. Then I created a quick test of a moving light.
You can see the light bounces on the bottom block, generated in real time. The image below shows a simple test of Lumen real time GI with two blocks, one on top of the other. If this is your case, you can enable Lumen by going to Project Settings and then, under Rendering, set the “Dynamic Global Illumination Method” to Lumen and then restart the editor. The idea is to provide realistic lighting, with GI bounces and reflections, that will improve the overall visual fidelity of a game.īy default, Unreal Engine 5 has Lumen enabled unless you have converted your project from UE4 to UE5.
Lumen is a fully dynamic global illumination system designed for next generation consoles (and, obviously, high end computers).
I am coming back to Unreal Engine 5 and this time I have decided to test Lumen, the new lighting system.
