Ever have a scene with a ton of different objects, all (or some) of which have meshSmooth enabled in the viewports? It can take a long time to go through your objects and set all of their meshSmooths to "visible only in renderer" (assuming that's what you need to do because your viewports are getting slower and slower as you model more and more)....so I wrote a script to do just that.
Run this script with your scene open, and it will cycle through all of your objects and set their meshSmooths to "render only" (ie...change the little lightbulb icon in the modify panel). I find it very handy!
Btw...this script is setup as a macroscript so you can add it to your right-click menus. Just run the script with max open....goto Customize-->User Interface--->Quads--->In the dropdown for catagories click on modifiers on there should be one now called "meshsmoothOff" that you can add to your rightclick menus.
