Exact integral equations for the radiative transfer in a coating on the exterior of a rectangular corner are derived. The model includes shadowing effects of the substrate and diffuse reflections at the substrate surfaces. The integral equations for the source function and the interface intensity are solved by a Gaussian quadrature integration method. The directional emittances of the coating at various locations are evaluated. Influence of substrate properties, scattering albedos and optical thicknesses on the emittance is examined.
