Branch Node

Description

Provides a dynamic branch to the shader. If input Predicate is true, the return output is equal to input True. Otherwise, it is equal to input False. Shader Graph determines the return output per vertex or per pixel based on the shader stage. It evaluates both sides of the branch in the shader, and discards the unused branch.

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

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;
}
