Description

Left eye shadow dithering stops working at a certain distance away from the light.

To recreate this behavior with any project, follow those steps: 

  1. Create an empty level
  2. Add a static mesh and a backdrop mesh (cube)
  3. Create two spotlights that will cast an overlapping shadow on the backdrop mesh (crank up the intensity)
  4. Each spotlight should have a source Radius of 15 or more (the bigger the source radius, stronger is the artifact)
  5. Open Project settings > Engine > Rendering > Shadow maps method > Virtual Shadow maps
  6. Launch in Standalone game with Emulate Stereo turn ON
  7. Get your camera closer from the overlap section of the shadow
