 The 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.

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

...

– 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

...

amount of Noise generated. Higher values

...

create smaller, finer noise.

Lacunarity – (question)

...

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.

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.

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 will be inverted as well.

Placement

Image Removed

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

Image Removed

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.
