Licensee note:
"I haven’t tested with Ray tracing. I currently have lumen enable and it’s occurring there."

Steps to Reproduce

[Link Removed]

  • Open any scene or create a new on and add a directional light and some basic shapes
  • Be sure to have lumen enabled
  • After that you can start to toggle the lighting components
  • Try disabling everything and then only have “Direct lighting” enabled. You’ll notice that the screen stays black

[Link Removed]

  • Instead, I would expect to see the direct lighting from the directional light.

Note this issue occurs only for Direct Lighting, Dynamic Shadows, and GI when the Diffuse is not active
