In the manuals for Commotion, there is some examples of where the Z-Buffer is used to render realistic smoke and fire. Now that I am working daily now with Lightwave, and wanting to integrate the two packages better, what graphic format supports the Z-Buffer, or how does this work?
What formats support this, or do I need to render something extra out of Lightwave?
I don't know about smoke and fire... the only z-depth plug-in that I remember was the true camera blur. This would take a grayscale version of your CG rendering and use it for depth of field. Just render out a z-depth matte from Lightwave... this is not like RLA magic, and more like a compound blur.
