This page contains information about the V-Ray Gradient Ramp Texture.

 

Overview


 Gradient is a texture map that can easily create and edit gradients useful in many different situations.

Node


The TexGradRamp node provides inputs for controlling various texture properties. They correspond to parameters in the section below.

 

 

Settings


 

 

Type – Specifies the type of gradient ramp to create:

Four corner – A gradient that transitions linearly between colors assigned to each corner.
Box – A gradient with a box radial transition.
Diagonal – A gradient with a diagonal transition.
Lighting – A gradient based on the light intensity.
Linear – A gradient with a simple linear transition.
Mapped – Specifies a map to use as a gradient.
Normal – A gradient based on surface normals and the camera.
Pong – A gradient with a diagonal transition that repeats in the middle.
Radial – A gradient with a radial transition.
Spiral – A gradient with a circular transition.
Sweep – A gradient with a linear sweep transition.
Tartan – Creates a gradient with a plaid pattern.
Position – Allows the user to specify a Gradient Position.

Gradient Position – Specifies the position of color in the gradient that is returned when Type is set to Position.

 

Gradient Noise


 




Type – Specifies how the colors are randomly distributed across the gradient.

RegularA plain noise with a non-fractal function.
Fractal
A fractal algorithm to generate the noise.
Turbulence
– A turbulence based noise type is used.

Amount – How much noise is introduced.

Size – The scale of the noise.

Phase – Controls the speed of the procedural's noise.

Low Threshold – Sets the Low threshold.

High Threshold – Sets the high threshold.

Smooth – The amount of smoothing of the noise.

 

Color Tweaks





Mult – Specifies a strength multiplier for the texture color.

Offset – Color corrects the texture by adding the the RGB color values specified here to the RGB color values in the texture.

Invert – When enabled, inverts the resulting texture color.

Alpha Tweaks




Source – Specifies where the alpha channel is drawn from.

Alpha – Alpha channel is drawn from the texture.
Color 
– Alpha is generated from pixel intensity.
Opaque
– Alpha channel is fully opaque.

Use – Differentiate between textures exported from different applications. You can choose between Color Intensity (3ds Max) and Color Luminance (Maya).

Mult – Specifies a multiplier for the texture alpha.

Offset – Specifies an additional offset for the texture alpha.

Invert – When enabled and Invert from Color Tweaks is also enabled, the resulting texture alpha is inverted as well.


Placement





Placement Type – Specifies the way the valid portion of the texture is applied.

Full – Uses the full valid portion of the texture.
Crop – Allows the user to specify a section of the texture using the parameters below.
Place – Allows the user to specify a section of the texture and how to place it using the parameters below.

U – Specifies the U coordinate of the valid texture sector.

V – Sppecifies the V coordinate of the valid texture sector.

W – Specifies the width of the valid texture sector.

H – Specifies the height of the valid texture sector.

Jitter – Controls the amount of random placement variation.

Tile U – Enables horizontal tiling.

Tile V – Enables vertical tiling.

UV Noise



Enabled – Enables noise for the texture.

Amount – Specifies the amount of noise to add to the texture.

Levels – Specifies the amount of noise iterations.

Size – Controls the scale of the noise.

Animated – Enables the noise to be animated.

Phase – Controls the noise phase.
