It'll look awesome.

Thats looking very nice, well done

How long does it take to generate?

It doesn't appear to tile. I assume thats planned?

Nice job though, I'm impressed.

It takes 135 seconds to generate the six textures (so about 22 seconds per view), running at 20% of a 2 Ghz CPU.

It does not tile, but that's normal, it's applied onto a cube. I could show the other 5 textures and you'd see that their seams all match perfectly.

that seems quite slow to generate, whats taking the time the perlin noise?, the texture generation dependant on terrain factors? etc
did u try the new perlin noise its quicker for 3d noise
theres a nice implementation in the glsl forums at www.opengl.org
(not that im advocating perlin noise for terrains though it looks crap :) )
