The C4DtoA plug-in is distributed as a tar archive which contains an installer bash script. To install it, simply follow these steps:
Unpack the archive.
tar xvf C4DtoA-3.3.3-linux-centos7-R23.tar.gz
Run the install.sh script. Note, that you need root privileges to run the script.
cd C4DtoA-3.3.3-linux-centos7-R23 sudo ./install.sh
Specify Cinema 4D install folder. The script looks for Cinema 4D in the default installation folder (/opt/maxon). If you have a custom install, press 1 and specify the path of the bin folder.
The installer creates an uninstall script into the plugin folder (e.g. /opt/maxon/cinema4dr23.008/bin/plugins/C4DtoA/uninstall.sh) which you can run with root privileges to remove all installed files.
Alternatively you can safely delete the C4DtoA folder manually from the Cinema 4D application folder (e.g. /opt/maxon/cinema4dr23.008/bin/plugins/C4DtoA).
