The installers will install the plugins directly into the plugins folder for your copy of Cinema 4D.
When using the installers they expect to find Cinema 4D at its default install location.
For windows users you have the option to select a different root folder to tell the installer where it should look for the Cinema 4D folders. By default this is set to "C:\Program Files\"On Windows
If the installer can't find Cinema 4D at these locations then you will not be given the option to install the plugins for those versions.
Zip files are also included if you wish to manually install the plugins yourself. Just make sure to delete the every version of the plugin in the folder, except the one that matches the version of C4D you are installing for. Note that the 2023 version is marked as R27 in the zip file.
Development of the plugin is being done by @kentbarber.
Available for Cinema 4D R20 through to Cinema 4D 2023 on both macOS and Windows.
Since this is a one man operation please forgive the quality of the videos and marketing material at this stage. Things will improve over time.
