My first project

If those are made within TG it's an awesome technique. I guess you used your vector displacement for this, just noticing your other post. Great stuff, but please give us some insight in the rock formation part.

Great work
This technique is an order of magnitude over what I've seen created in terragen alone!
I guess this really narrows down the field for the Cliff challenge! (joke!)

I suppose you are using Houdini for the base shape and export those to VDM?

There's more to it though, since (according to Matt, because I asked him last year) VDM does not allow for closed loops/open holes and thus true arches are not possible.
Unless the base houdini mesh had an "arch" at its side or top and you rotated the whole thing in TG.

I suppose you are using Houdini for the base shape and export those to VDM?
------------------------------
Yes and no    I used cinema4d and houdini, but vdm i exported from houdini!!
-----------------------------
I didn't rotate shape in terragen.. i used other technique  of "arch" at its side without any rotation
----------------------------
I wish terragen have an ability to create caves and holes with VDB stuff...  VDB+microdisplacement = awesomeness !!   
A long time awaited vertical strata +rectangular noise = is too an awesomness 
----------------------------
Dune, i'll give you a little tips a bit later i promise!!!

So this comes into Terragen as an image map displacement, or object? OUTSTANDING!
I get what you are doing, I just was making sure I get the method to connect to Terragen.

[Artice-3d]

luvsmuzik, thanks a lot     This is the vector displacement map droped into terragen and then enhanced further!!!

[Kadri]

Nice thread and experiments

[j meyer]

So how are the arches done?
Two planets or a plane and a planet?
Please tell us.

[Dune]

You can do a lot with a bunch of cubes stacked in a certain rough shape, then apply the same displacement setup to all. Vdisp will then be a little trickier, however.

[Artice-3d]

Thanks Kadri!!     j meyer - Arches is a vector displacement 

[Artice-3d]

Dune i can't use cubes in a rough shapes, because terragen doesn't love rough edges at all 

[Dune]

I meant 'rough' as in roughly stacked. But the cubes can be made with softer edges, and they will 'catch' that displacement.

[j meyer]

I know about your VD experiments, but with VD alone it`s impossible
as Martin (Tangled-Universe) pointed out already.
Please explain.

------------------------------
I tried this stuff already with no success!! Edges need to be too soft for displacement    So it looses it cubes shape.. i thought to make rectangular as possible, bit for now terragen can't handle such stuff, you know that    I even tell you more, my base VD shape is complete from cubes  but it's a secret.. 
------------------------------
Arch-is a vector displacement, but with extra stretch from sides.. that's all    nothing to hide..
------------------------------
But..... Terragen can handle textures not bad, so if developers will make a rectangular noise texture, like in vue it will be a game changer
