You can include paths to additional INI files within the local plugin.ini file; 3ds Max processes these files as if they were part of the original plugin.ini. This capability is helpful in settings where several systems on a network are using the same plug-ins. The network administrator maintains only a single remote INI file, rather than having to update each machine individually.
Example: To add remote INI files to your local plugin.ini:
myremote=\\remote_dir\remote_plugin.ini
anotherdir=d:\test\extra_plugin.ini
The next time you start 3ds Max, it will load plug-ins from the directories defined in plugin.ini, as well as plug-ins in any remote INI file specified in plugin.ini.
You can add as many remote INI files as you need, making it easy to organize groups of plug-ins.
