1. Photon Illumination of DGS Materials in Mental Ray for Maya    3dtotal.com

Shiny: Shiny describes how blurry the specular reflects are and only affects materials set with a Glossy value. It works a little like the Cosine Power parameter of the Phong shader. The lower the Shiny value the glossier or more blurred the specular reflections will be. For example, higher values above 100 produce hard specular reflections and very low values of less than 1 make glossy reflection appear like a diffuse reflection.
