This page contains information about the V-Ray Noise Texture.



 The TexNoise node generates a procedural noise texture. It uses an implementation similar to that of Maya. It uses two colors that can also have texture maps assigned to them.

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






Type – Specifies the type of noise to be created through the Noise procedural.

Inflected Perlin
Marble(with Perlin)

Dimensions – Specifies the type of space for the texture.

2D – Applies the noise as a 2D texture.
3D – Applies the noise as a 3D texture.

Color A – Controls the first of the two colors used by the Noise procedural.

Color B – Controls the second of the two colors used by the Noise procedural.

Amplitude – Controls the range of the Noise.

Threshold – Specifies a value added to the noise function. Note that values above 1.0 are clamped.

Frequency – Controls the the amount of Noise generated. Higher values create smaller, finer noise.

Lacunarity – Controls the fractal lacunarity, that is the size distribution of the holes. 

Octaves – Controls the number of functions to use when calculating Perlin Noise.

Time – Specifies the time of the noise. This acts as a third or fourth dimension to the noise generating function.

Inflection – Enables and disables the inflection effect.

Clamp – When enabled, the texture colors are clamped.

Implode – Controls the amount of implode performed on the UVW coordinates.

Implode Center – Specifies the center of the implode effect.

Origin – Controls the translation for the noise UVW coordinates.

Scale – Controls the scale for the noise UVW coordinates.

Wrap – Enables the wrapping of the texture.

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.
– Alpha is generated from pixel intensity.
– 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 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 – Specifies 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.
