Extra Shader Nodes is a collection of 66 math-focused node groups designed for use in Blender's Shader Editor. The pack expands upon the default math operations by providing dedicated nodes for advanced mathematical functions and complex number calculations.

The collection includes 25 extended trigonometry nodes for standard numbers alongside 24 extended trigonometry nodes specifically for complex numbers. Additionally, it features 14 math nodes for complex number operations and a domain coloring node for complex number visualization. Five miscellaneous utility and dependency nodes are also included to support the main node setups.
