Cinema 4D R21 Released

The new major version R21 of Cinema 4D has been officially released and is now available for download. Everyone can now create accounts on the new MyMaxon portal (my.maxon.net) and download the latest version of Cinema 4D.

The most significant changes are:

  • Only one version of Cinema 4D exist.
  • Existing C++ plugins must be adapted and re-compiled for R21.
  • Building C++ plugins requires Visual Studio 2017 or Xcode 10.
  • A new licensing system replaces the old, serial number based system. The SNHookClass plugin type has been removed.

  1. Adding the manuals and symbols section in the python documentation is probably the best thing in the new docs 👍. I always wished though there was a more direct connection between the Python and C++ SDK. Maybe you could add links to all (relevant) C++ manuals in the future? You can use them separately of course, but it would be really convenient.
