##  This is the render settings script by Colin Braley
##  This After Effects script is used to turn on some settings that are useful to setup before rendering
##  These incluse beging able to set the motion blur, shutterAngle, quality settings, resolution, and visibility settings
##  of layers and comps.  You can also affect nested comps with this script.
##  To run this script have a comp selected in your project window and then run it.
##  I have tested this script pretty thouroughly, but if anything get's messed up you can't blame me.
##  Posted to aenhancers.com on January 30, 2006
##  For more info, click on the help button on the script palette
##  Enjoy.
