Inspired by Feenixnz who was asking about canyons and cliffs. That was three days ago :) lol
Some tweaking later I have this. I'm not happy with the fore ground, the stones just seem to blind together :( I like the shape of the sky though that has worked:)
Also there's loads of holes in the strata, you can see daylight through the worst of them. Changing the patch size worked but lost the "sharpness" of the strata ... ideas?
cheers and C&C welcome :)

ps tgd in the file shearing forum
I think the tips of the strata are way too sharp. They looks like hard blocks. They need to be softened or beveled if such is possible. That alone would look more like the real thing. :)
nice image with realistic strata...
NKAID...
Very good. I particularly like the sexy curves of the strata.

Just might possibly be perceived by some to be a smidgeon of a tad of a nats baw' hair too sharp, but no way "way too sharp". (imhtg-cmhahtd-o).

Okay! ;D
I think it's a great strata render, and thanks for sharing the TGD - I still need to get round to really getting to grips with strata, and I'm sure this will help.
;D ;D ;D
if we know its name and its location...
... it would not be undiscovered... ::) ::) ::)
NKAID..
Interesting work so far, good start!
I don't have real problems with sharp strata, I think they don't look bad at all, they just need a little break up.
If you intend to make them less sharp try to increase the strata angle a tad bit, say from 0 to 10 degrees (I can't remember the exact name of the setting, but the default = 0)
If you add an extra compute terrain and disable blend as stone density in your fake stones I'm pretty sure they will work fine and as you expect.
I'm working on a strata-project as well now and am experiencing the same artefacts. I notified PS about this problem.
Cheers,

Hi TU
I only really made up this image as a demo for Feenixnz and I did learn a lot about "extreme" displacements in the process. Particularly I was attempting to get overhanging strata, like in FrankB's image in 3DWorld. Looks like the strata displacement is "amped" by horizontal displacements so the strata actually increased the visual effect of the overhang. I'll try the extra compute terrain and disable blend as density for the stones if I get the chance. (Why is "blend as stone density" even there at all?)
Cheers

You're correct about the horizontal displacements working with the strata. Very powerful if you can get it at your hands.
I think the "blend as stone density" function was experimental, though not sure.
I have experimented with vertical strata some times, maybe you find it fun to try as well...just add a stratashader and set the bottom 2 values for tilt/angle to ~89 degrees (as long as it is <90 degrees, 90 degrees or greater won't work)
Then breaking up all strata with some powerfractals and I'm pretty sure you'll have very interesting results.
Martin
Using a power fractal with offset works. The vary the amount of lateral displacement I use a power fractal mask. The redirect may also work this way. I suppose clamping a fake stone shader might work also.
Wow, cyphyr, this is cool. Great lighting and good choice of coloring. This image has the "better than real" look. Great.
cyphyr, I loved those colors so I had to plug those shaders into a WM terrain I had just done.
I know the walker no longer works well here, it was just a test. Thanks for the surface.
