OK. Thanks Oshyan.
I now realize that I can run the full TG on my Mac or PC because I went ahead and got the upgrade from v0.9. I don't use it on two machines simultaneously. I just like to work with the Windows version for now until multi core support is implemented. My XP machine's single core is faster than one core on my Mac.
As for my experiments here, I kind of went too far with it. Long render times when I need to look at simpler things in TG2 and then come back to this to improve it but I just wanted to know how far I could go with a style that Mojoworld can achieve. This is just a small rough test render. The detail is bad on the displacements but I have test rendered sections at high detail and they turn out OK. Very interesting in fact, because I think TG2 might actually have less bad artifacts than Mojo when pushing displacements. These rocks have more roughness than my previous posted render. In that one, where you see the blend at the bottom of the spike (an inverted crater by the way) the textures look really nice. I expected more dodgy artifacts but it seems with rough textures on big displacements that they turn out pretty good. I notice for example in a perlin ridge terrain, overlying smaller displacements don't mess up noticeably where they cross a ridge. They do in Mojo. However to give Mojo credit here, it does have a lot of power to change the effect of the fractal. There are lots of ways to control where the displacement is orientating from e.g. world position, surface position, undisplaced surface position and more.
