Lighting Fails to Build with LPV

I’m attempting to create a dynamic emissive material as per the directions listed:
Light Propagation Volume now works with Emissive Material!! - Rendering - Unreal Engine Forums!!=


  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, check Force No Precomputed Lighting.

  5. Add a post process volume and set to Infinite Extent (Unbound). LPV section is visible with parameters.

  6. Attempt to rebuild the lighting, and it fails.
