XPresso Tag
This page covers the XPresso tag in Cinema 4D, the entry point to node-based scene programming. Assigning it to an object opens the XPresso Editor, where object properties can be linked and automated — from simple parameter connections to complex procedural rigs, no scripting required.
By assigning this tag to any object in your scene, you can create your own expression using CINEMA 4D's powerful expression builder, XPresso.
The XPresso Editor will then open automatically. Using XPresso, you can create almost any type of behavior for objects and link behaviors to one another, allowing endless automated interactions between the objects in your scene.
To learn about the XPresso Editor, see XPresso Editor ( and Thinking Particles).
