Here is a little script I created to help in the process of making sure smooth preview was optimized for viewing and rendering. It allows you to iterate over a ton of objects and set them however you need. Setting the Preview to zero and the Render to two allows for multiple objects to be viewed in Maya and yet at render time it will still smooth them nicely for you. It’s a very convenient script to have, although you do still have to remember to hit 3 on all of your objects to activate Smooth Previewing. I still haven’t figured out how to do that thru a script…

You can use the the individual Apply buttons next to the three option to apply settings seperately or use the Apply All button. The Script doesn’t care and will carry out your orders without complaint, as a good script should.
