Setting a plug-in path
Use the SDK preference settings to assign additional paths for MotionBuilder to search so that you can access plug-ins that reside in external directories.

From the Preferences window, select the SDK option.
The SDK preference setting displays.
Click Add.
The window Add Additional Paths to Search for Plug-ins appears.
Navigate to the plug-in folder.
Select the plug-in folder and click OK.
Any plug-ins found in the specified location are now available to MotionBuilder.
