Steps to Reproduce

  1. Enable Clear Coat Second Normal in the project settings.
  2. Create a simple clear coat material that writes a normal map to the clear coat bottom normal and enables clear coat via the material pin. Also add parameters for the roughness and clear coat roughness
  3. Assign the material to a mesh in a level with a directional light.
  4. Rotate around the object and observe the speculars disappear when viewing the mesh from some angles (see the video)
  5. Increase the roughness and observe the bottom layer flattens out substantially in the shadow side. (See the screenshots with the different roughness/clearcoat parameter combinations)
