Cool models, all of you. Remember that the best way to get a great render in Z is to setup your final doc at Double size. That way you can hit the Zoom Palette AAHalf button and make it look cleaner. Also, to make the mesh cleaner, make sure quick 3D Edit is turned off and Smoothing is turned on Tools Palette Display Properties. My Alien is Rendered at 3100w X 2200h.
Good Luck all.
