This pack contains three SBSARs:
Non-uniform rotation greyscale and colour
These nodes rotate the input based on a greyscale intensity input. They can be used with noises and patterns and can yield very different results. Some examples are in the images above but the best thing to do is to just play around with them.
This node allows you to alter the hue, saturation and lightness of a colour input depending on one input for each of them. This makes you able to quickly create colour variation from a solid colour, or add variation to a flood filled pattern.
The nodes are free for commercial and personal use.
