SCINODES2 is an addon containing useful (I think?) utility nodes for making Blender shaders.
SCINODES2 is free, but you can set your own price if you wish to support me.
See simple examples of what SCINODES2 can do.
With Spectral Glass 4 and Physical Iridescence you can create materials that would otherwise require a special spectral rendering engine.
Easily create grid-based layouts for repeated patterns and procedural HUD and UI shaders.
Perform bitwise operations on 8-bit integers, do math with complex numbers, and twist your shapes beyond control!
