Adds nodes to generate random and predictable colors in several ways.

Pattern Rand - Generates pseudo-random values in the range [Min, Max];

Pattern Wave - Smooth color transition along a sine wave.

Pattern 3Range - Extended version of the Rand pattern. Three ranges[Min, Max] that generate pseudo-random values. Added the ability to customize the distribution of values from each range.

Note!

The scripts are written in the OSL (Open Shading Language).

For Blender versions (up to and including 3.4): Rendering is supported ONLY on the Cycles Engine and CPU.In Blender versions starting from 3.5 and higher added OSL support with OptiX on the GPU.

Doc_RCN.zip contains help videos on how to install the addon, activate OSL, also the principle of the patterns.

A copy of the node description will also be available in the Blender Text Editor after installation.
