You're right BabyDuck not much useful doc for the plugin. Its mostly trial and error on how to get the plugin to work. And I have trialed and errored on this plugin but no such luck. I went into the [I] and see the commands. I ran this command
'utexportmesh c:\projects\characters\scenes\char01.mb' from the script editor but I got this
// Error: utexportmesh c:\projects\characters\scenes\char01.mb; //
// Error: Syntax error //

Any suggestions anyone?
