What is happening here? It looks like it’s raining.
Unreal 5.3.2, using Lumen. The point lights are stationary.
Looks beautiful for being a f up…
It’s got to do with runtime GI.
Lumen is obviously failing miserably at it.
This could potentially be due to the sheer number of fixed lights you have in the scene.
Or due to the model that the pointlight is in - reflection off of it.
For starters, you should probably add a light profile to the point lights, preventing bleed above/behind/around as much as possible.
Then you probably have to limit the number of bounces to 2 or 3 or even just 1.
The more bounces you calculate, the more glamoring/rain you get, probably.
Speaking of, if the top of the light funnel thing is reflective, make it fully opaque.
It will probably help limit the effect if its due to a bounce like im guessing…
