• BRDFCarPaint - Simulation of metallic paint with base color, random metallic flakes and a coating layer.
• BRDFFlakes - Only the flake part of the car paint BRDF.
• BRDFHair3 - A BRDF optimized for hair. Use with GeomHair.
• BRDFLayered - A weighted combination of any number of BRDF plugins. (This is also known as Blend material in the UI of V-Ray for 3dsMax and Maya.)
• BRDFSSS2 - Subsurface scattering for materials like wax, milk, resin, marble, etc. Use BRDFSkinComplex instead for skin.
• BRDFSSS2Complex - SSS with even more parameters.
• BRDFScanned - This loads a real world material sample scanned to a file by our custom hardware. Email us for details.
• BRDFSkinComplex - A skin-specific SSS plugin.
• BRDFStochasticFlakes - A new plugin for randomly generated tiny sparkly particles. This produces a glittery material like ones found on some clothing and footwear.

5.2. Textures and UVW generators

The BRDFs have many Color, AColor and Float parameter slots that can be textured. You will usually just load texture files, but V-Ray also offers many procedural textures, as well as texture plugins that serve as modifiers (i.e. apply some simple function, combine textures, extract data from one of the channels etc.). There are over 200 hundred texture plugins, so we will only look at the most important ones. Many of the plugins are made for specific host applications. Apart from the texture data itself, V-Ray uses UVW generator plugins to generate UVW mapping coordinates or modify the original data from the geometry source. Using a UVWGen plugin is not obligatory.

For texture files:

• TexBitmap - Uses the data from a bitmap buffer (see next two points) with some additional parameters, like color multipliers, tiling etc.
• BitmapBuffer - Loads an image file. A large number of formats are supported - lossy/lossless, from 8-bit to 32-bit. This is not a texture plugin and its only purpose is to feed data to TexBitmap. It has some options for filtering and gamma.
• RawBitmapBuffer - Same as BitmapBuffer, but use uncompressed data from memory, instead of a file on disk.

Textures that modify and combine colors:

• Tex

Some procedural textures:

• Tex

Finally, the UVW generators:

• UVWGenChannel - Modifier for UVW data coming from the geometry source. Has transform, wrap and crop parameters as well as the option to get UVW data from another UVWGen plugin.
• UVWGenEnvironment - Used to map spherical, cube, etc. textures on the environment color slot or on dome lights.
• UVWGenExplicit - Define explicit UVW data from a texture.
• UVWGenMayaPlace2dTexture - Similar to UVWGenChannel, but with more options.
• UVWGenObject -
• UVWGenPlanarWorld -
