Can I create a dynamic lighting with emissive material?

4.18.2

  1. Add r.LightPropagationVolume=1 to my console variables .ini and restart.
  2. enable Emissive (Dynamic Area Light) in the material.
  3. Add a directional light, enable Dynamic Indirect lighting, set Dynamic Shadow Distance StationaryLight to 10, and set intensity to .004
  4. In World Settings, I check Force No Precomputed Lighting.
  5. Add a post process volume and set to Infinite Extent (Unbound)

I see the LPV section with parameters.
I attempt to rebuild the lighting, and it fails. Solutions?

Light Propagation Volume now works with Emissive Material!! - Rendering - Unreal Engine Forums!!=
