Increase Lumen render distance?

Development Rendering
, , ,

The following worked for me in my use case:

  • Enable “Use Hardware Ray Tracing” in project settings. Restart if required.
  • These console commands:

r.LumenScene.FarField 1
r.RayTracing.Culling.Radius 100000 (couldn’t go beyond this number)

  • Extras:

r.LumenScene.FarField.FarFieldDitherScale 10000
(helps soften the edge of where lumen reflections kick in)

r.Lumen.Reflections.ScreenTraces 0
(gets rid of the jarring transition between lumen and screen scace reflections, which can look quite different from each other)

Enable “Hit lighting for Reflections” in Ray Lighting Mode under Lumen in Project Settings. (produces more accurate representation for reflections in the Lumen scene)

Hope the above helps, please add to this if more is discovered as I really struggled. :sweat:
