arch_mtl What is the mia_material ? The mental ray mia_material is a monolithic material shader that is designed to support most materials used by architectural and product design renderings. It supports most hard-surface materials such as metal, wood and glass. It is especially tuned for fast glossy reflections and refractions (replacing the DGS material) and high-quality glass (replacing the dielectric material). The major features are: - yet flexible. mental ray 3.6 enhancements and mia_material_x The material comes in two variants, the mental ray 3.5 compatible mia_material and the new extended mia_material_x. ...has some additional parameters relating to bump mapping described on page Bump. ...supports setting to 2 for enabling "ambient occlusion with color bleed" (see page AO with bleed). ...returns multiple outputs in the form of a mental ray struct return. Structure of this Document Physics and the Display A Note on Gamma The solution is to introduce a mapping of some sort. Tone Mapping
