Just a quick animation with Terragen 0.9. Just recently learned how to do animation on it (not like it is hard to do). About 723 frames long, at 390 * 292. If this is an okay animation I'll render it again at a larger resolution.
Obviously Terragen 0.9 doesn't have the power of TG2 but I use the free version of both.
