Function Node


Description

This node is used to write your own custom functions, you can have multiple functions inside a single node and even call one function from another.

When to use the Function node:

  • to implement large functions via code;
  • to copy some functions from external sources;
  • if you are a programmer you got used to write code and feel uncomfortable with node-based workflow;

Please keep in mind that some functionality might be unavailable as graph nodes yet, but via code you have access to everything in UNIGINE's graphics API. See the SDK/data/core/materials/shaders/render/common.h for the list of common shader functions which can be used in the Function node to implement you custom functionality.

For example, there is no dedicated node that can get a random color but our Shader API offers a randColor(float seed) function, which can be used in a Function node as follows (see the image above):

Source code
void getRandColor(float a, out float4 c)
{
    c = randColor(a);
}
