I assume that you've just racked up a second PFS on top of the other larger fractal for this, Mr. L. This does work a treat for distant shots but, if you're close to your terrain surface then this really messes up the foreground, I'd like to be able to limit the secondary fractal to break up the lined areas only, probably achievable with the distribution shader, or(my preference) a surface layers' slope constraints but it's a tricky balancing act.
I wasn't aware that you couldn't go past 40 octaves in a fractal shader, this'll be the same for all shaders that use octaves then, water, strata, etc? Not that I'd probably ever need to go so high but it'd be good to know anyway.
