XPresso

Cinema 4D node-based logic and automation

Overview

XPresso is Cinema 4D's node-based system for creating logic, automation, and procedural setups. Connect nodes to control object parameters, perform calculations, and build interactive rigs.

Tips

• Drag object parameters into the XPresso editor to create nodes.
• Use Range Mapper to remap values between ranges.
• The Python node allows custom scripting.
• Use Iteration to loop through objects or elements.
• Right-click nodes for more options and help.

Basic Nodes

Node / Code	Description
`Constant`	Outputs a constant value (number, vector, etc.).
`Result`	Displays the output value for debugging.
`General`	Provides general-purpose operations.

Calculation Nodes

Node / Code	Description
`Math`	Performs mathematical operations (add, subtract, multiply, divide, etc.).
`Range Mapper`	Maps an input range to an output range, with curve and clamp options.
`Compare`	Compares two values and outputs a boolean result.
`Clamp`	Restricts a value to a specified range.

Logic Nodes

Node / Code	Description
`Condition`	Outputs one of two values based on a boolean input.
`Switch`	Switches between multiple inputs based on an index.
`Boolean`	Performs logical operations (AND, OR, NOT, XOR).

Data Nodes

Node / Code	Description
`Object`	Accesses object parameters and properties.
`Time`	Provides the current time/frame information.
`User Data`	Accesses custom user data fields.
`Iteration`	Loops through objects or elements in a hierarchy.

Vector Nodes

Node / Code	Description
`Vector2Matrix`	Converts a vector to a matrix.
`Matrix2Vector`	Converts a matrix to a vector.
`Vector`	Performs vector math and operations.

Scripting & Special Nodes

Node / Code	Description
`Python`	Executes custom Python code inside XPresso.
`Xpresso Tag`	Attaches XPresso logic to an object.
`Port`	Defines input/output ports for nodes.
`Link`	Links objects or tags dynamically.
