Find Plug-in (C++ only) path by server name
From The Foundry MODO SDK wiki
Sometimes you want to diagnose if a plug-in dll file was loaded or where it is located on disk. The Host service provides a way.
h = lx.service.Host() f = h.LookupServer('command', 'morphDeform.mapName', 0) print f.Module() # Result: #'deform.lx' # Note: External plug-ins will show the full absolute path
