Painting with Photons - Mental Ray for Maya “The volume shader defines the coloring of a visible ray that passes through empty space. When photon reflections overlap, the mental ray renderer uses sampling to to have a volume shader assign to its Photon Volume component. Volumetric Shader through Mental Ray by Silvia Palara, USA Introduction Photon Volume Shader - For every MR volume shader, plug in its photon shader. Maya / Mental Ray: itouchblog.de?v=gO42parB9G4 but I haven't had This will allow photons to pass through the volume. Like photon shaders, photon volume shaders do not deal with rays (like material and volume shaders) but with photons. Basically, photon volume shaders. In particular, we will be using Mental Ray's Parti-Volume shader to create scene, and the Parti-Volume Photon shader for volumetric caustics.

The Material Shaders rollout provides controls for the main kinds of component shaders you are likely to assign. Each shader component has a toggle at the left of thread of hope mp3 name. When the toggle is on, the shader is used in rendering. When the toggle is photon volume mental ray, the shader is not used, even if it has been assigned. In addition to any of the usual 3ds Max materials, the surface component can be assigned the following mental ray materials or shaders:.
See note below. The shadow component can be assigned the following shaders:. The photon component can be assigned the following shaders:.
The photon volume component can be assigned the following shaders:. The bump component can be assigned the following shaders:. The displacement component can be assigned the following shaders:. The volume component can be assigned the following shaders:. The environment photon volume mental ray can be assigned the following shaders:. You must assign a shader to the material's Surface component. Otherwise, the mental ray material will not be visible when you render.
Basic Shaders group Surface Shades the surface of objects that have this material. In addition to any of the usual 3ds Max materials, the surface component can be assigned the following mental ray materials or shaders: The old version of the shader continues to be used in the scene until you reapply it in the Material Editor. Caustics and GI group Photon Assigns a photon shader. Photon shaders modify the appearance of caustics and global illumination.
They modify light energy luminous flux rather than color radiance. The photon component can photon volume mental ray assigned the following shaders: Extended Shaders group Bump Assigns a bump shader.
Bump shading for mental ray materials is similar to using a Bump map in standard materials. The bump component can be assigned the following shaders: Shader Ocean Shader List. Shader Material to Shader Shader List. Optimization group Flag Material as Opaque When on, indicates that the material is fully opaque.
This tells the mental ray renderer that it doesn't need to process transparency for this material, or to use the shadow shader if one photon volume mental ray been assigned. This can improve rendering time. Parent topic: Car Paint Material Shader. Edge and Edge Shadow. Material to Shader. Shader List. Texture Wave. Transmat Photon. Two Sided. Water Surface.
