cb_ocSetup.mel 1.5.0 for Maya (maya script)

This script was designed to help implement a lighting scheme which was used on a project I worked on. The lighting solution involved the use of a Mental Ray ambient occlusion node whos output was plugged into the ambient color channel of all the materials in the scene. The purpose for this was to provide fill lighting throughout the scene which did not excessively wash out textures or flatten the final images. This lighting solution was extremely effective for us but proved very labor intensive to set up in scenes containing 100+ materials. This script was written to automate that setup process.

The function of the script is very simple, it generates an ambient occlusion node and plugs that nodes output into the ambient color channels of all materials in the scene with the exception of the Maya defaults lambert1 and particleCloud1. The attributes of this scene-wide effect can than be universally controlled by editing the central occlusion node created by this script.

To-Use: Simply run the procedure in the desired scene.

Please feel free to use this script or any part of it as you see fit. I believe very strongly that the free exchange of tools in the creative community serves to strengthen it. I do ask that if you make use of this tool that you inform me via the contact page on my website www.chrisrigs.com.
