Nodes > Functions > Util > Custom Code

The Code Node allows custom GLSL shader functions to be written directly in the graph system. Code Nodes are powerful tools with many features, so be sure to check out the Code Node Guide for more information.

For quick reference on all the built-in operations available, select one of the code snippets from the Example Code dropdown.

To see more examples, check out the Code Node Template.

Inputs

Name	Type	Description
Value 1	float	User-defined inputs appear on the left. This is the first input for the default example that appears when a Code Node is created
Value 2	float	User-defined inputs appear on the left. This is the second input for the default example that appears when a Code Node is created

Outputs

Name	Type	Description
Result	float	User-defined outputs appear on the right. This is the output for the default example that appears when a Code Node is created.

Properties

Name	Type	Description
Title	string	The title of your function. The title appears at the top of the Code Node and is used by the Custom Code Global node to select Global variables
Version	string	The version of your custom function, useful to help keep track of code variants you create. The default value is 0.1.0
Stage	dropdown	For Code Nodes that are attached to Output containers in a VFX system, selects whether the Code Node is operating in the Vertex or Pixel shader
Description	text	Optional description text to explain the Code Node’s function
Errors	text	Errors in your code will appear in this window
Example Code	dropdown	Load a premade code snippet, useful for quick reference of built-in functions. Selecting a code snippet will replace all the code in the code window.
Height	int	The height of the code window, in pixels
Code	text	Custom shader functions are written here, and is where input and output ports and global variables are defined.
