Aye, the scales are a bit large here. The near crater is actually 50m in diameter. Needs a bit of work yet, I just lifted the shaders from another shader test.tgd and laid them over the original scene(Crato) as they were.
Thanks for the input, WIP shaders.
Also, this one took about an extra 30% render time over the original Crato scene and that one has water in all the craters. It's still a very reasonable render time, though. On my old 1.35ghz, single core pc with 1GB RAM this one took something over 6 hours, Crato took 4. I desperately need an upgrade. I'd imagine that most of you could render this in a half hour to an hour.
Frank could probably render it in about 10 seconds on his i7!
