What is New in S24


Python version updated to 3.9.1

Cinema 4D S24 run on Python 3.9.1.

This update is important for Mac OS users since it’s the first official version to support Apple Silicon.
Fixing zipfile, SSL, and all no ARM-ready python modules. It also fixes pip for Mac OS which was not working correctly within Cinema 4D.

Python 3.8 and Python 3.9 offer some nice new features so take a look at:

This update shouldn’t break existing Python 3.7.7 code, but it may in some exceptional cases so please take a look at Porting to Python 3.9.


Python 3.9.1 doesn’t support anymore Windows 7.

Regarding the Cinema 4D integration, the environment variable C4DPYTHONPATH37 is renamed to C4DPYTHONPATH39.
Preference folders is also update from python37 to python39.

Nodes API

This release is the first one to release publicly the Nodes API.

Find a non-exhaustive list of what the Python exposure of the Nodes API is capable of:

  • Access nodespace and belonging graph from a Node Material and SceneNodes.

  • Use a graph. e.g. iterate each node/port, retrieve the value of a port, retrieve node property(e.g. its name), sets a node property, instantiate/remove a node, group nodes.


It is not possible and not planned to compile and execute a custom graph node at the moment.
It is not possible and not planned to implement custom Python node. Python being mono-threaded this will drastically lower all the Nodes performance.

The entry points to the nodes are either the c4d.NodeMaterial, or the c4d.BaseList2D through BaseList2D.GetNimbusRef() or BaseList2D.GetAllNimbusRefs() methods.


The c4d.NodeMaterial is historically the first class introduced to access NodeSystem.
In the future this class will be deprecated as most of the use cases are covered by the c4d.BaseList2D and the maxon.frameworks.nodespace.NimbusBaseInterface.

It’s recommended to take a look at the C++ documentation to have more information about the Node API structure.
