This is one of my first script. Same like align tool I adapted this one from 3Ds Max. This script will createa a GUI where it will show all the lights and its attributes. Where you can change the attr of all the light without selecting each and goto Attribure Editor or Channel Box to change it.
Notes :Lighting -> Light Lister. GUI allow you to even change the Name of the lights from the interface itself.
Light Attribuites :This is the place where it shows the basics attributes of each lights.
Attribuites :On/Off, Name(Right Click to change the name), Color, Depth Map On/Off, RayTrace Map On/Off, Depth Map Size, Filter Size, Bias Size, Shadow Rays and Ray Depth Limit.
