Pepper currently does not support the Renderman Shading Language. Only the Pepper built-in shaders can be used.

Surface Shader
- reflectiveplastic: Like plastic, but can be reflective and transparent. Additional coefficients Kr for reflections (default: 0), Kt for refraction (default: 0) and eta for refraction index (default 1.5).
- reflectivemetal: Like metal, but can be reflective and transparent. Additional coefficients Kr for reflections (default: 0), Kt for refraction (default: 0) and eta for refraction index (default 1.5).
Light Source Shader
- shadowpointlight:: like pointlight, but with raytraced shadows.
- shadowspotlight:: like spotlight, but with raytraced shadows.
