So I have read the online docs and found nothing (not 100% sure what to look for any way ) that talks about the clipfx or the userSetup any help would be great. p.s.  the script is based on the default Tesselation.mel from Paul Anand, The script sets the curve shade perscion to 3 for all objects.  Big deal right? well what it does is set your shaded objects to be smooth (same as key 3) but unlike  the #3 key your wire views  of your objects won't look like they were set to patch per. of 60:) so it keeps the view nice and clean in wire or shade.       I THINK you mean you want the .mel to run during each startup, right? The way I got scriptsMenu.mel to load up each time automatically was to place : {scriptsMenu;} at the end of my /usr/aw/maya1.0/scripts/startup/initialLayout.mel this loads scripts menu each time. The place to try SHOULD be: (disclaimer here... your own risk... etc.) /usr/aw/maya1.0/scripts/startup/initialStartup.mel   It is HIGHLY recommended not to change any of the scripts in the /usr/aw/maya1.0/scripts directory.  There isn't any reason that this should be done.  Also, any changes there can't be supported by A|W. As for executing a command on startup, place the commands into the maya/scripts/userSetup.mel file.  By default it doesn't exist; Maya will look for it and if it does exist, the file will be sourced.   You should add to your .maya file in your home directory  lines : setenv MAYA_PLUGIN_PATH "/usr/aw/maya/devkit/plug-ins:/usr/people/duboi/maya/plugins" setenv MAYA_SCRIPT_PATH "/usr/aw/maya/scripts:$HOME/maya/scripts:/usr/people/duboi/maya/scripts" setenv MAYA_FILE_ICON_PATH "/usr/aw/maya/bitmaps:$HOME/maya/prefs/bitmaps:/usr/people/duboi/maya/bitmaps" Change /usr/people/duboi/maya to the name of directory where your scripts are. You can check if this env is ok after maya launch by typing : system printenv. You should see your script directory in the path printed. Make sure that the name of your command is the same as your file name. If the name of your command is toto, your script file should be toto.mel. I think there is no need to add stuff to userPrefs.mel to do that you want.
