Lumen GI and Reflections feedback thread

Hello,

Lumen indirect lighting has world normal aligned artifacts.
Seems to be independent from lighting and object position.
Artifacts disappear when turning off Lumen.
No Lumen settings seem to affect the artifact (I’ve tried detail and global tracing, and hw raytracing as well)

Steps to reproduce:

  • Create a new project with the ‘empty’ template
  • Add a sphere or any round mesh to the scene
