Branch Node

Description

Provides a dynamic branch to the shader. If input Predicate is true, this node returns input True, otherwise it returns input False. The Branch Node evaluates the Predicate per vertex or per pixel depending on shader stage. Both sides of the branch are evaluated in the shader, and the branch not used is discarded.

Ports

Name	Direction	Type	Binding	Description
Predicate	Input	Boolean	None	Determines which input to return.
True	Input	Dynamic Vector	None	Returned if Predicate is true.
False	Input	Dynamic Vector	None	Returned if Predicate is false.
Out	Output	Dynamic Vector	None	Output value

Generated Code Example

The following example code represents one possible outcome of this node.

void Unity_Branch_float4(float Predicate, float4 True, float4 False, out float4 Out)
{
    Out = Predicate ? True : False;
