Just fired up the erosion beta for the first time to do a test....haven't yet touched the atmosphere on it
[attach=1]
trying to match an image taken by a friend
[attach=2]

My fake stones are a little pink, and it needs the trees broken up a bit

I used the wear maps from erosion to place gravel and make rock slides coming down the far valley

the hardest part for me is trying to flatten that far vertical cliff, didn't do a very good job...make me wish for a lattice deformer :)

Looks great.

Have you tried the Simple shape shader or paint shader?
I don't mind that part at all actually. I have seen something like that -kinda- in a photo.
Those structures have a name but i can't remember.

mdharrington

tried everything I could think of  :o

Honestly my node tree is such a mess, I can barely tell where to make a change or not....I'm sure it can be done, and I may give it a bit more effort later

Just my 4th scene in TG, so still learning the importance of node structure and proper naming...and combining masks in proper ways so little changes can be easily added.

There are many ways but the easiest probably is putting a "Simple shape shader" where the cliff is and using negative displacement.
Not elegant but could work.


mdharrington

thanks....ill give it a try

Kadri


The above method is dirty fast and easy.
A mask (with a paint shader,simple shader etc.) applied to the displacement of the mountains is another way.

Kadri


An animation with that scene would be nice :)

I plan to at some point....

Unfortunately have some real work to do as well  8)

Real work sucks...mostly  :D

I haven't been on here in a long time (nor used terragen either) but I came on tonight and saw your post it reminded me of a solution I found a while back. I used it for a stepped strata, but it looks like it could work for you here.

Maybe blended using a simple shape around the desired mountain (because my method made a step in the whole terrain at the desired height).

I can't remember exactly what settings I used, but I recall the 3 "fractal terrain" nodes were identical except for the displacement offset (height of the steps I wanted), and then blended by altitude using the "distribution shader"s.

I remember being inspired by efflux's work using the "Tex coords from XYZ" node. I used it differently than he did here but it worked.

I'm sorry I can't open the tgd at the moment, my system crashed over a year ago and I haven't been on it since.

Hope it is of some help.

How the heck could you last over a year without Terragen...I'd be stark staring mad in that time.
