In response to shred300: I wouldn't call something made up of a Lightwave object/ Carrara object/ Strata object in a Vue landscape "mixed-media" because you can render, then shift the camera and render again, and it's the same scene.

It's the prescence of 'post' itself that changes it over to a mixed-media.

Part of the question that you posed was: "Why is post considered as 'evil'?" The implication is that somehow, post is 'cheating'. It's a way of covering up your mistakes and shortcomings. Which, definitely, it is not. Just depends on where you're going with the end product.
