It would be possible to make a nodegroup which could control a global
"render area" with a few value nodes inside the group.
Using a script to tack this nodegroup on the end of all material node
setups wouldn't be too hard..
Would something like that work?
Of course, it would be nice if there was a more native way to do it.. ;)
