This page contains information about the V-Ray Noise Texture.
Overview
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.
Settings
Type – Specifies the type of noise to be created through the Noise procedural.

Perlin
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 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.
Default Color – Specifies a color when there are no valid uvw coordinates. Mult – Specifies a multiplier for the texture color. Offset – Color corrects the texture by adding the RGB color values specified here to the RGB color values in the texture. Invert – When enabled, the resulting texture color is inverted. Source – Specifies the alpha source from Alpha, Color, and Opaque. Use – Differentiates 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, the resulting texture alpha is inverted, too. If disabled, just the color is inverted. Placement Type – Specifies the way the valid portion of the texture is applied. The options are Full, Crop, and Place. U/V – Specifies the U/V coordinates of the valid texture sector. W – Specifies the width of the valid texture sector. H – Specifies the height of the valid texture sector. Jitter – Specifies the amount of random placement variation. Tile U – When enabled, there is horizontal tiling. Tile V – When enabled, there is vertical tiling. Enabled – Enables the UV noise. Amount – Specifies the UV noise amount. Levels – Specifies the UV noise iterations. Size – Specifies the UV noise size. Animated – When enabled, the noise is animated. Phase – Specifies the UV noise phase.Color Tweaks

Type – Specifies the mapping type. UV Name – The name of the UV channel that is used. Repeat U – Multiplier for U values. Repeat V – Multiplier for V values. Coverage U – U values are remapped to 1.0. Coverage V – V values are remapped to 1.0. Translate Frame U – Translates the frame in U direction after applying rotate_frame (and before wrap, coverage, clamp). Translate Frame V – Translates the frame in V direction after applying rotate_frame (and before wrap, coverage, clamp). Rotate Frame – Rotates the frame after applying UV noise. Rotate UV – Rotates the UVs after mirroring. Offset U – Offset added to U before mirroring (after wrap, coverage, clamp). Offset V – Offset added to V before mirroring (after wrap, coverage, clamp). Noise U – Noise magnitude multiplier in U direction. Nose V – Noise magnitude multiplier in V direction. Mirror U – When enabled, every other tile outside the [0;1] range is mirrored in U. Mirror V – When enabled, every other tile outside the [0;1] range is mirrored in V. Wrap U – When enabled, U values outside the [0;1] range wrap back to [0;1]. Wrap V – When enabled, V values outside the [0;1] range wrap back to [0;1]. Stagger – When enabled, tiles in the V direction add +0.5 to the U value for a 'staggering' effect. Type – Specifies the type of projection mapping to use from the following:None Planar Projection Camera – Selects a camera. Projection Camera (LOP) – Same as Projection Camera parameter but for use in the LOP context. Fit Fill – Specifies how the projection is fitted. Vertical – Fitted vertically. Fit Type – Specifies the type of fitting to use: None U / V Angle – Specifies the U / V mapping angle. Film Gate W / H – Specifies the width / height of the film gate. Hide Backface – Determines whether to project on back faces of polygons. Hide Occluded – Determines whether to project on occluded points when using the Perspective Type. Object Space – When enabled, the projection is applied in the object space of the currently shaded geometry. Use Reference Points – Uses reference mesh/rest inputs for projection calculations. Mapping Type – Specifies the type and shape of the texture from the following: Spherical, Angular, Cubic, Mirror Ball, Screen, Spherical (3ds Max), Cylindrical (3ds Max), Shrink Wrap (3ds Max), and Spherical (V-Ray). Horizontal Flip – Flips the environment horizontally. Vertical Flip – Flips the environment vertically. Horizontal Rotation – Specifies the horizontal rotation (left and right). Vertical Rotation – Specifies the vertical rotation (up and down). Texture Rotation – Specifies the texture rotation. Wrap U – If true, U values outside the [0;1] range wrap back to [0;1]. You can choose between the No Wrapping, Wrap and Mirror Tile options. Wrap V – If true, V values outside the [0;1] range wrap back to [0;1]. You can choose between the No Wrapping, Wrap and Mirror Tile options. Wrap X – If true, X values outside the [0;1] range wrap back to [0;1]. You can choose between the No Wrapping, Wrap and Mirror Tile options. Crop U / V / W – Enables or disables cropping in the U / V / W direction. DUVW Scale – Specifies an additional scale factor for the texture derivatives. Ground – Enables ground projection of the texture. Ground Radius – When Ground is enabled, this specifies the radius of the ground. Ground Position – When Ground is enabled, this specifies the coordinates for the ground.Mapping
