Sadly the smaller (say 480x320) preview doesn't always look the same as the full quality render. Even with all the settings optimized and checked (the post effects). But I am used to that. JWildfire sometimes has the same problem with porting parameters to the renderer.
Thank you very much for this tutorial - especially the tip about the ani keyfr (f) button. It streamlines the workflow greatly. I would never have looked at it otherwise having little interest in animations. I'm also glad you pointed out that anti-aliasing was part of the Viewing function - hadn't seen the tool tip and would not have guessed was tucked away in there.
