Can a plugin use the native Node Editor for its own graph?
-
Is there a public Cinema 4D SDK API for displaying a plugin-defined graph in the native Node Editor, with custom nodes, ports, and connections, independently of the built-in material and Scene Nodes graphs?
I found NodeSpaceInterface, NodeSystemClassInterface, NodesGraphModelRef, and NimbusBaseInterface, but I’m unclear which API provides the graph host and Node Editor context for an independent plugin graph. Is this supported in Cinema 4D 2026, and is there an SDK example of the required registration and host setup?
