Material: Using common functions from within custom expression nodes

Hello, for example: I have a custom function expression with for-loops and i want to call sub-functions. This wasn’t possible because custom expression code is wrapped inside a function and hlsl doesn’t allow functions within functions. So I searched some time and found solutions which work on former versions. (before 4.16) Unfortunately, these tricks doesn’t work anymore. But i found a new solution i want to share. Goal: Write a custom voronoi function for a procedural generated texture. …

Just don’t use the #ifndef stuff. 4.26
