This page provides information about the Generic material in V-Ray for Rhino.
Overview
Generic is a special V-Ray material, that allows for better physically correct illumination (energy distribution) in the scene, faster rendering, more convenient reflection and refraction parameters. Within this material you can apply different texture maps, control the reflections and refractions, add bump and displacement maps, force direct GI calculations, and choose the BRDF for the material.
UI Options
The Generic material settings are organized in Basic and Advanced modes. You can switch the mode from the toggle button under the Preview Swatch or globally from the Configuration rollout of the Settings tab.
An Add Layer button is provided for some V-Ray materials, including Generic. You can select an additional layer that can add up to the appearance of the material. For more information, see the Layers section on Materials page.
From the Add Attribute button, you can select additional attributes that can add up to the appearance of the material. For more information, see the Attributes section.
The context menu of the Color slot provides options to Copy and Paste, as well as to Reset the color.
A Reset option is provided in the context menu of each Number Slider. You can reset the slider value to the default one.
Attributes
The attributes from the following expandable menus are available for the Generic material.
Notes
Materials with Normal opacity mode are now migrated to Stochastic opacity mode.
The Highlight Glossiness parameter is a legacy plugin. It is migrated from previous versions; however, if it is disabled, the row is hidden and its value is set to 1.
Use the VRayMtl/VRayBRDF whenever possible in your scenes. This material is specifically optimized for V-Ray and often GI and lighting is computed much faster for V-Ray materials than for standard materials. Many V-Ray features (e.g. light cache, render elements ) are guaranteed to work properly only with VRayMtl and other V-Ray compliant materials.
VRayMtl can produce reflections/refractions for matte objects - see Wrapper.
The 2D mapping method will ignore the Tiling parameters specified in the textures themselves.
- Since V-Ray 5, both Reflective Coat and Diffuse Coat are legacy layers that can no longer be created or duplicated. However, the layers used in old scenes can be converted to VRayMtl through the Migrate Now button, located in the Asset Editor. The Diffuse coat layer can also be deleted and replaced by the parameters of the Coat and Sheen base layers.
- Having a very large number of scene objects using materials with 2D Displacement may substantially prolong the geometry compilation phase of the rendering process.
Prior to V-Ray Next, Update 1 the Fog Scattering section was known as Translucency.
