Yes bagginsbill...I think you can attach it to a light. And I am doing just that. The problem was the textured plane I was using was not working as it was supposed to or as my previous experiences suggested it would.
It dawned on me that using a high contrast black and white image to a flat plane and adding transparency would work better than using a full color plane with no contrast image and no transparency. So Redhawk over at Seventh Complex cooked me up a few optional textures with some software that works only on PCs that creates this sort of Caustic-like textures. A few regular color and because he agreed with my idea of using high contrast B&W on a trans plane, did me a few variables of that to both positive & Negative to try.

That's it man! Now as soon as I have the time to play with them I will try these textures out and see what comes of it. Because I have done this sort of thing creating regular ambiance shadows in the old app before I am confident I can pull it off again.
