Hi All, I don't seem to be able to stretch the voronoi 3d diff shader more than about 5 times it's width in the Y direction. Is it just me, am I missing something or is this a limitation?
Try this.
This makes no difference at all try it with a SSS or power Fractal!
A flat surface will only take the fractal value at altitude=0. If we're at the origin, then y is pretty much altitude.
So if you expand y in your noise pattern, the surface is still only ever going to see the pattern at y=0.

Apologies, I overlooked the vertical part. I am still working on this but it does seem unlikely to work as Hetzen's explanation makes sense.
Slope does affect the appearance of stretching but on a vertical surface I would expect infinite stretching.
And what if you stretch in X and rotate?
Does weird things to the landscape! I've solved the problem to some extent by using lateral displacement only. Will post some pics soon.
