I was looking at Vue’s ability to make planets, and then I vaguely remembered some old 2D planet generator software I used years ago. I just found it again — Flaming Pear’s $59 LunarCell (planet generator) + Glitterado (star-field generator) plugin combo for Photoshop. If none of the thousands of free NASA and Space Observatory photos are suitable for your iClone sci-fi competition backdrops, this could be what you want to generate the perfect planet or starfield…

I’m guessing, but you could presumably do something like stick a really big detailed planet image on an iClone 2D plane in the background of the scene, then slowly draw it towards a spaceship as the spaceship remains static — thus giving the feel of a following camera during planetfall, but without actually having to set up any model animation or camera paths?
