what i'm trying to get is once GI is calculated, each object in my scene knows the amount
of light hitting it. and i the end result i want is to take that lighting value, and have it
control parts of materials, which i used to do tons in poser6, wether it be plugin or tex file

an example, is a light meter, you would feed the value into a gradient of a rainbow
then the more light hitting the object (balls work good, round :P) and it changes from
say blue (too low of light) to red (too much), poser 6 had a diffuse node for this
i've seen plugins that can do part of it, they only work with direct light, and ignore shadows
and most of my work at the moment is using GI, as trying to have realism :)
some objects in the world respond differently to the amount of light on them
skin for example is one of them

if someone wrote a plugin to read and use I maps in the texture room, that be great
outputting a value 0% to 1000% or so, easily usable :)
