The ZIP File you downloaded contains a "plugin" folder and a "doc" containing a ReadMe and eventually further documentation. Close the Cinema 4D application and copy the content of the "plugin" folder into your Cinema 4D's "plugins" folder. Now start Cinema 4D again.
- Unpack the downloaded ZIP file into a temporary location of your choice (e.g. your Desktop). Inside the ZIP file you find a "plugin" folder that contains all the files that need to be copied to your Cinema 4D installation.
- Find Cinema 4D's plugin folder: To find the folder where Cinema 4D expects 3rd party plugins start Cinema 4D and go to the preferences (from the Edit > Preferences menu). You can see the path to the preferences folder at the bottom of the dialog. There is also a button to open the folder in the File Explorer / Finder. Click the "Open Preferences Folder..." button.
The path on Microsoft Windows is typically something like:
C:\Users\Name\AppData\Roaming\MAXON\CINEMA 4D R15_12345678\
The path on Mac OSX is typically something like:
/Users/Name/Library/Preferences/MAXON/CINEMA 4D R15_12345678/
- Close the Cinema 4D Application.
- Copy the plugin files: In the Cinema 4D preferences folder you see a folder named plugins. Copy all the files from the downloaded "plugin" folder into that "plugins" folder.
- Start Cinema 4D again.
- Now the plugin should be installed and working within Cinema 4D. To make sure everything went fine you can check the Console in Cinema 4D. Use the "Script / Console..." menu to open the console. You should find a message showing that the plugin has been loaded, including the version number.
