Custom Code Sample

This material graph sample demonstrates how to create and use nodes containing a custom shader code.

Albedo RGB value for the material of the Mesh Opaque PBR type is specified directly using a Float node (casting to float3 is performed automatically).

The Function node has two float input ports (A and B) and two float output ports (return value Out and C output). They are automatically added according to the function signature:

Source code (Shader)
float function_1(in float a, in float b, out float c)
{
	c = lerp(a, b, 0.5f);
	return a+b;
}

A and B values for the custom function node are provided by Slider parameter nodes (adjustable via the Parameters panel in UnigineEditor) connected to it.

The result of linear interpolation between A and B values is connected to the Roughness input port of the master material node, while the sum of A and B — to Metalness.

Finally, the data output is passed to the Final node.
