Hey, I found that after updating to UE 5.1 my emissive materials were not lighting my scene up as well as in previous UE verisons.
Here the emissive materials (particularly animated ones) had an awesome effect on the scene, the blue and purple light above would move and change and affect the world around it.
Now jumping in to 5.1 all of that GI seems to be lost and the only way to replicate something like what it was is to up the emission a load, but this leads to over exposure and is not ideal.
I’m sorry I don’t have a past screenshot to reference this to - but has anyone run in to something similar? using emissives for lighting with Lumen was an awesome workflow for me, but seems a bit less effective in this new update.
But here’s an old example of the GI having an awesome effect on the whole scene in Lumen with 5.0
