Branch Node

Description

Provides a dynamic branch to the shader. If input Predicate is true the return output will be equal to input True, otherwise it will be equal to input False. This is determined per vertex or per pixel depending on shader stage. Both sides of the branch will be calculated in the shader, even if one is never output.

Ports

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