The current implementation of clear coat materials is very simple and does not model the following effects:

  • The clearcoat layer is assumed infinitely thin, which means that there is no refraction
  • The ior of the clearcoat and base layer do not influence each other, which is inaccurate
  • There is no scattering between the clear coat and base layer
  • There is no diffraction
