Every operator has a Parameter Window (Press P to toggle). This is where you configure what the node does.
Parameter Modes
- Constant (Gray): A static value you type in.
- Expression (Blue): A Python script that calculates the value.
- Export (Green): A value being pushed from a CHOP (using “CHOP Export”). Think green for CHOPs.
- Binding (Purple): A bi-directional link between two parameters.
Best Practices
- Use Expressions for simple logic.
- Use CHOP Exports for high-performance data driving (it’s faster than expressions for many channels).
- Use Binding when building user interfaces or custom components, allowing parameters to be controlled by a script, a CHOP, or a UI element simultaneously.
