This page provides information about the Gradient texture in V-Ray for Blender.
Overview
The V-Ray Gradient is an utility texture that creates a 3-color gradient texture.

Node
Color 1-3 – The three colors used in the resulting texture. These can also be mapped to a different texture for each of the 3 colors.
Parameters
Type – Select How the gradient's appearance is calculated.
Linear – Shades from the left to the right in a straight line.
Radial – Shades from the center to the outside in a circular pattern.
Middle – The middle color position.
Noise Type – Dropdown to select how the colors are randomly distributed across the gradient.
Regular – A plain noise, this is not a fractal function.
Fractal – A fractal algorithm to generate the noise.
Turbulence – A turbulence based noise type is used.
Noise Amount – How much noise is introduced.
Noise Size – The scale of the noise.
Noise Iterations – How many iterations of noise there will be.
Noise Phase – Controls the speed of the procedural noise.
Noise Low – Sets the Low threshold.
Noise High – Sets the high threshold.
Noise Smooth – The amount of smoothing of the noise.
Compatibility – Allows you to match the result of the texture in Blender to that in either 3ds Max or Maya. If Alpha From is set to Maya:
3ds Max – The resulting alpha of the texture is the intensity of the texture.
Maya – The resulting alpha of the texture is the color luminescence.
Invert – When enabled inverts the colors in final result.
Alpha From – Determines how the alpha of the result is calculated:
Force 1.0 – Alpha is always 1.
Compatibility – Depends on the selected Compatibility option.
Self – The calculated alpha of the texture.
Invert Alpha – Inverts the alpha channel if Invert is also enabled.
UV
Placement – Select how to place the texture.

Crop
Place
U – U coordinate of the texture sector.
V – V coordinate of the texture sector.
W – W coordinate of the texture sector.
H – Specifies the height of the texture sector.
Tile U/ Tile V – Enable to choose between a horizontal or vertical tiling.
UV noise on – Enables the noise.
UV noise amount – Specifies the UV noise amount.
UV noise levels – Specifies the UV noise iterations.
UV noise size – Specifies the UV noise size.
UV noise phase – Specifies the UV noise phase.
Animate UV noise – If enabled, the noise is animated. Use the UV noise phase to animate the noise.
