Well nothing to say much, if you’re into maya rigging you can’t possibly haven’t came across cometTools. I’m a big fan of Michael comet and his tools specially PSD and his mel script.I noticed cometSaveWeights.mel is not working exactly as it has to be on maya 2011, as Autodesk have done some changes to mel commands, I have attached edited version of script which works very well on 2011.

Edit: Enable normalize weights before you save weights in maya 2011,
“;” was missing in some line, that is fixed now.
