Terragen was the first rendering program that I could ackshelly understand - the gui seemed beautifully logical compared to anything else I'd tried. And the surface texturing controls are a lot more understandable than the Bryce DTE, which I'll never master. Wish that Bryce had the atmosphere control that Terragen has, then it would be perfect :^) And the water in Terragen is beautiful as well. Bryce is more flexible, but once Terragen gets object import and a more controllable terrain editor it will kick ass!
