Issue with Lumen, Black Lines Appear

Hey guys,

I’m having an issue with Lumen when I move the camera these black lines seem to appear across the scene. Everything is broken into pieces with the minimum thickness recommended as stated in the docs, I’ve tried multiple cvars to see if anything changes but no luck.

I suspect something strange is happening with the distance fields or the DFAO? See images below.

Any ideas?




Use the lumen scene view and distance field views under visualizers to try to see what’s going on.

I’m not really seeing an issue with the lumen scene or the mesh DFs, maybe I’m wrong? I checked the global DFs and the lines seem to be visible on there.



Same problem black wired shadow lines, found that SkyLight - Cast Shadows is the culprit, by disabling it disappear, at least for me.

Same issue… 5.2, skylight - cast shadow didn’t fix it for me.
