This page contains information about the V-Ray Noise Texture in V-Ray for Modo.
The V-Ray Noise Texture generates a procedural noise pattern using two colors or texture maps.
UI Path: ||Shading viewport|| > Shader Tree > Add Layer button > V-Ray Textures Procedural > V-Ray Noise
Color 1 – Controls the first of the two colors used by the V-ray Noise procedural.
Color 2 – Controls the second of the two colors used by the V-ray Noise procedural.
Size – Controls the scale of the noise function.
Phase – Controls the speed of the V-Ray Noise procedural's animation.
Iterations – Number of iterations for the fractal generator. Disabled when using a Regular Noise Type.
Low – Sets the low threshold. Controls the color of large details: low values are lighter, higher values are darker. For more details, please see the Thresholds example below.
High – Sets the high threshold. Controls the color of the smaller details: low values are lighter, higher values are darker. For more details, please see the Thresholds example below.
Type – Allows one of three type of noise to be set by the user to be used by the V-Ray Noise procedural. The choices are Regular, Fractal, and Turbulence. For more details, please see Noise Types examples below.
Regular – Plain noise, this is not a fractal function.
Fractal – Uses a fractal algorithm to generate the noise, the Interactions channel sets the number of iterations for the Fractal Noise.
Turbulence – Using an absolute function this generates fractal noise to make fault lines.
Examples in this section use Regular as Noise Type and have Size set to 0.05 with Invert enabled.
Note: High values must remain higher than the Low values in order for contrast to take place. If the two values are equal, or if the High value is set to a number lower than the Low value, very little change from the default will be seen. Numbers very close in value will give very contrasted results.

Fractal: Size 0.1
