Python in Cinema 4D


Python can be found in different parts of the Cinema 4D eco-system. It can be used to extend, automate or improve workflow by creating custom scripts or plugins.

Being all the functions of the “c4d” module calling their C++ equivalent, executing a Python code, invoking only Cinema 4D SDK functions, takes almost the same time of the equivalent C++ code.

A python interpreter called c4dpy is available to execute python code with the C4D API outside of Cinema 4D. Moreover c4dpy bring extra features such as Autocompletion or Debugging for Python Script (Plugin are not supported). See the c4dpy manual.


The Cinema 4D Python interpreter versions are:

  • Windows: Python version 2.7.14 (default, May 3 2018, 18:05:57) Build with MSC v.1500 64 bit (AMD64) (Microsoft Visual Studio 2008)
  • Mac OS: Python version 2.7.14 (default, May 5 2018, 00:43:48) Build with GCC 4.2.1 Compatible Apple LLVM 9.0.0 (clang-900.0.37)


There are general places where Python can be found within the Cinema 4D eco-system:

  • c4dpy. A custom python interpreter which supports Cinema 4D modules.
  • An optional python file called before plugin registration.
  • Python Libraries. Information about 3rd party libraries / modules.
  • Python Console. The Python Console / interpreter within Cinema 4D.
  • Python Script Manager. The Script manager to edit and run scripts within Cinema 4D.


Python is embedded in various places of Cinema 4D, such as:


Use of Python in these situations is context-specific, which means some stuff are not possible to do (e.g. insert new object in a document from a Python Tag). See Threading Information.


In addition Python in Cinema 4D can be used to creates the following plugins in order to extend and create new Cinema 4D component:
