Why are Maya Plug-Ins for Linux a different file extension (.so) than on Windows (.mll)? Is there any way to convert from one to the other?
My attempt to open on V.Linux a Maya scene created in V.Windows failed because it couldn't find a couple of standard plug-ins. Has anyone noticed that V.5.0 Linux ships with less standard plug-ins than V.5.0 Windows?
it should not be a problem opening Maya binary scenes (win) on a linux machine. check the manuals but I dont think there are more plugins on the windows platform, perhaps your file where used with an external plugin.
when it comes to different plugin formats its platform specific, you cannot use a *.so plugin on windows or a *.mll file on linux. it has to do with how the plugins are built. its like open word from microsoft on native linux 
it just wont work.
mll is simply a dll file, which is the same as a so file but we are talking two different platforms, the binaries wont match.
hope this helps!
