V-Ray for Blender provides a number of texture utilities to drive materials. These textures can only be used with the V-Ray Render Engine. See the links below for more information on specific textures.

UI Path: ||V-Ray Node Editor|| > Shader > Add > Texture Utilities

Bump Normal

Blend two normal or bump maps.                                                              

Clamp

Clamp the colors of textures.                                                               

Color Arithmetic

Perform an arithmetic operation between two colors/textures.

Color Correction

Apply various color corrections.                                                                                                                 

Color To Float

Convert a color or texture into a floating point value.                                                                                

Distance

Returns a different color based on a point's distance from an object(s) specified in a selection list.

Falloff

Produces a gradient texture based on the angular falloff of the surface of the geometry.

Float

Outputs a custom float value that can be used for any purpose.                                              

Float Op

Perform mathematical operations on float values.                                                                     

Float To Color

Convert the input scalar texture to a grayscale color.                                                 

Hair Sampler

Map color, incandescence, and transparency along the length of a hair strand.

HSV to RGB

Convert a color from an HSV color model to an RGB color model.                                  

Invert

Invert texture colors.                                                

Invert Float

Outputs the inverted result of a float input texture. 

Luminance

Wraps a color texture and outputs its luminance.       

Mix

Mix two colors or textures using a texture map or a solid color value.                                                                        

MultiSubTex

Distribute multiple textures to many objects via one single material based on specified IDs or random distribution.

Normal Map

Flip the color channels of a texture.                                                                                                                                                                      

Output

Perform various adjustments to a texture's value, such as multiplication, offset, inversion, and clamping.

Remap

Remap different types of values.                                                                                                                                             

Remap Float

Remap a value in the 0-1 range to another range.                                                                                                                          

RGB To HSV

Convert a color from an HSV color model to RGB.                                                                                                                     

Sampler

Create a color image that provides information about the scene. You can show any of the aspects as color blocks.

Set Range

Ramp a texture or a color.                                                                                                                                                                                            

Surface Luminance

Control luminance calculation.                                                                                                                

Triplanar

Assign bitmaps and other 2D textures to objects that don't have suitable UV coordinates.                         

User Color

Read user-defined object properties from the current material and convert them to a color value.

User Scalar

Read and return a single number value of the currently shaded object as a result.
