I'll upload the .tgd when I get home. As for the technique I used, check out this thread:
http://forums.planetside.co.uk/index.php?topic=231.0I basically just stacked a bunch of fake stone shaders on top of each other, then threw an image map shader on. When I first rendered the scene, which originally had no water, I got an image that basically looked like the texture I used, but with some bumps and lumps in it. I didn't get a coherent scene until I added water, which is what moodflow was missing in the above thread; if you add water (and position your sun well) you get a greater sense of depth in your image.
Unfortunately, I don't have any credits to give out for the texture... I'll upload it later, but I can't figure out where I got it from. =/ A good texture is key, baby.
