Maya
MEL script Installation instructions:
To make the scripts automatically execute at Maya startup, put them in the "Maya?.?/scripts" directory in your home folder. In Windows, this is under "/my documents". Generally, all scripts are tested in both Maya 6.5 and 7.0.
Put an entry inside the userSetup.mel file ( if you don't have one, then create a new blank text file with this filename ) that sources the mel file you just copied, i.e. :
source "newScript.mel";
Restart Maya.
Plug-in Installation instructions:
Put the .mll file in a place where Maya can find it, or load it manually through the plug-in manager.
