This page provides information about the Generic material in V-Ray for Revit.

 

Overview

Generic is a special V-Ray material, that allows for better physically correct illumination (energy distribution) in the project, faster rendering, as well as 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.

Add Layer and Add Attribute buttons are provided for some V-Ray materials, including Generic. You can select an additional layer or attribute that can add up to the appearance of the material. For more information, Attributes And Layers section.

Holding down Ctrl while having the Add Attribute or Add Layer menu open, allows selecting multiple entries without closing the dropdown.

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.

Notes

  • Use the Generic material whenever possible in your projects. 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 Generic and other V-Ray compliant materials.

  • The Generic material can produce reflections/refractions for matte objects - see Wrapper Material.

  • The 2D mapping method ignores the Tiling parameters specified in the textures themselves.

  • The 2D mapping (landscape) method only supports one UV mapping channel.
  • Materials with Normal opacity mode are now migrated to Stochastic opacity mode.

  1. Having a very large number of project objects using materials with 2D Displacement may substantially prolong the geometry compilation phase of the rendering process.
