Render Settings Script

Mon Jan 30, 2006 11:07 am

After recently rendering something, only to realize I left a few layers on draft quality, I decided to create a script that could turn on certain settings througout a slected comp, and it's nested comps. This script uses a UI and allows users to specify if they want Best quality for all layers, to set the comp's shutter angle, to turn on motion blur for all layers and the comp, to turn on pixel motion frame blending, and to desolo and activate all layers. THese settings can then be applied to a comp. An option can also be selected to have this affect this cimp's nested comps. Here is the script:

/*################################
##  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.

##  Enjoy.
