It's good to have different minded people working on the program.. [:)] That way, it is well rounded.

db4tech I think is more to learning how to get the renderer to be more photorealistic, while I like to make glass look better... My fascination with light is only to learn how to get it to scatter enough to mimic frosted glass, and/or colored glass. I have a house with a beautiful stained glass window that I have in mind to design, but of course I first have to wait until it is possible.. [:D]
