Hello everyone!
If I have Lumen on, when I move objects or character is moving - there is a trail behind them.
First of all turning the ‘Generate Mesh Distance Fields’ off in project settings helped but if moving is happening near the walls then the trail is still there. I have hardware raytracing support on.
Did anyone encountered that problem? I’ve tried changing anti-aliasing method - not working.
Lumen is temporal, it works by tracing(the expensive part) a fraction of pixels and rotates through the fraction over time every frame to save performance. If we trace all pixels for lighting every frame, the GPU would have a hard time remaining responsive.
It then uses TAA to smooth any noise from alternating tracing directions as well.
It’s “normal”, but the Lumen devs have no solution as of now.
