This page contains information about the V-Ray Bercon Noise Texture in V-Ray for Modo.


Page Contents



V-ray Bercon Noise is a procedural noise texture that offers a great deal of control. It allows you to change both the Noise Type and also to specify a Fractal type to use as well. If a texture is connected to the Distortion channel then this texture will be used to distort the noise produced.

Color 1 (map)  – Controls the choice of color for the dark color used by the texture.

Color 2 (map) – Controls the choice of color for the light color used by the texture.

Size – Controls the size of the noise procedural produced.

Low – Controls the color of the large details.  low values are lighter, higher values are darker.

High – Controls the color of the smaller details.  low values are lighter, higher values are darker.

UVW – Controls how the procedural texture is mapped and gives a choice between Normal, Radial and Spherical.

Noise Type – Allows the choice of which noise type to use for the procedural texture. Giving a choice between Perlin 2D, Perlin 3D, Perlin 4D, Simplex 2D, Simplex 3D, Simplex 4D and Worley (Voronoi)

Fractal – Allows the choice of fractals to be used by the procedural noise.  It allows choices of None (no fractal shall be used if this is selected), Fractal, Turbulence, fBm, fBm Turbulence, Hetero Terrain, Hybrid Multi Fractal and Ridged Multi Fractal.  When a choice other than None is chosen channels appear that allow control of the specified fractal type.

Distortion (map) – When a texture map is connected to this channel it will distort the V-ray Bercon Noise texture depending on the texture map.  Solid colors will have no effect and the more contrast in the connected texture, the more visible the distortion will be.
