# 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.

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