Compatible with R20 and higher.
All plugins will work on Windows and OSX, unless they are specifically stated that they are for only Windows or OSX.
For R20 users the plugins will work with all version of Cinema 4D unless otherwise stated. That includes BodyPaint, Prime, Broadcast, Visualize and Studio editions.
For R21 and higher all features of Cinema 4D are now in a single edition so all plugins from Plugins 4D will work.
All plugins have been tested on Windows 10 and OSX High Sierra (and up).
