The best place would usually be to post this in the World Machine forum, but it's not really
a to active forum.
I want to create a more alpine terrain if you understand what I mean. Something more like the images below:

I can't figure out how to make those type of erosions. I always end up with the same kind of thing like in the image below.
I'm really not good with World Machine, but is there anyone who can help me with this?
As you can see in the terrain I made there are erosions everywhere, but in the mountains over there are not.
How can I control this kind of thing?

Terje
I am not very good at WM2 either but I am getting 3 different ideas as how to approach this.....
1. you could use ramp as mask to the erosion node
2. you could use clamp on erosion node
3. there is a node called select slope, you could use the selected slope to mask the erosion
I hope this helps :)
Hi dhavalmistry,
I will try that and see how it goes.
Tanks.

Terje
I'm pretty sure you should be able to get results similar to the above entirely in the erosion nodes, depending on the shape of your base terrain of course (a ridged perlin probably being a good possibility). Experiment with the Rock Hardness and Sediment Carry, among other things. Thermal Erosion might also be a good pre-filter before the normal erosion filter, to give the right shape to the mountains.
But then, I am no WM expert either. ;)

Try a high rock hardness and a low sedimentary amount. I don't know that much about wm2, but i'm using 1.x since some years.

Goms
Hi Terje,
How are you going with this?
Cheers,
Martin
yea I am looking forward to the terrain as well...
Hehe.... I'm sorry, but I have no luck with this, but I'm
not even sure i plug the nodes in the right places either.
I've been away this weekend too, but if I make any progress
I'll let you know ;)
Regards,
Terje
How about this?
Cheers,
Martin
That looks pretty damn nice Martin! Can you also export the erosion layers as masks?

Of course, default workflow for me :)
World Machine will allow multiple types of masks for each terrain type. It is quite powerful, but I prefer Terragen 2's methods.
i think it depends. if you want realistic erosion WM is IMHO the best way. Also i can imagine with the newer version that supports multithreading, it shouldn't be a problem (and pretty fast) to build a terrain in TG2, export it with 8192^2 and then import it again. (you might even use a merge shader to get the difference and then only use this to keep the fractal detail.)
Hi again,
I don't think I was too clear on what I want. I've painted a little on the image
below to try and better demonstrate what I mean.
The red lines I've made is suppose to represent the main shape of the mountains.
As you can see, there aren't very much erosion going on where the lines are.
I understand that some of that is probably cause by a lot of snow cover, but
isn't it possible to make something similar to this with World Machine?
Regards,
Terje
what you need is "Sharp Ridged" as the style in advanced perlin node

How close was my example?
(FYI, my example uses sharp ridged advanced perlin)
Hello Martin,
Well...... what you have is something I think I can reproduce. Don't get
me wrong, it's a cool terrain, but it's just not quite what I'm looking for.
I found a image in the World Machine gallery that shows what I want. It's
posted below. Problem is that the person who made it used Maya for the
base mesh and then took in in to WM for detailing.
(http://world-machine.com/gallery/images/1282441766_Mount_Everest_3d_by_rhodeder.jpg)
Is this possible to recreate with WM alone?
Regards,
Terje
Just mask your erosion node in WM. That way you limit where it takes place and how much is present.
Hi Terje,
No worries, it was just an attempt.
Without reading your reply I played a bit with it in the last hour. See below.
This example has a bit of the branching and sharp ridges you mention.
After reading your reply I see what you mean.
I know that image, it's pretty cool :)
Without looking at the textures I think this should be possible.
My first guess is a low-octave lowish persistence ridged perlin noise as a base.
Then the erosion should be masked out to taper off at the maximum height.
Or perhaps you set erosion very high to get smooth slopes.
There are a couple of ways you can approach this.
I'lll have a further play with it :)
Martin
That's cool and please do post your results here if you don't mind :)
I'll keep trying myself, but I really do suck with WM. I don't even understand
how to mask the erosion like you guys are trying to tell me ??? ::) hehe
Regards,
Terje
What do you think of this. I have to admit, this is very hard to get that certain look you are after. Could be a program limitation.
Hey Chris,
Could you maybe change the angle?
It's a little hard to see the shapes from that angle.
Regards,
Terje
How is this angle?
Well, can't say i did not try.
That looks pretty interesting Chris.
Can you put the .tmd file here if you'd like?
I can post mine as well if anyone's interested?
Cheers,
Martin
Sure, i have another one you all can play with as well. ;)
Is this any closer?
- Oshyan
Hi Oshyan,
That looks a little bit closer to what I want, but it is still missing that massive part if you understand?
Regards,
Terje
Tweaked Oshyan's setup a bit...
nice terrain TU!
Not sure what you mean by "massive" really. The scale is often more determined by how you surface map something and/or what objects or other visual cues (e.g. atmospheric haze) you put in to imply scale. The terrains Martin and I have posted could easily be used at "massive" scale in TG, making for very large mountains, and would give a great impression of scale with appropriate atmospherics, plant populations, etc.
Now if it's the *shape* that's still a problem, that's another matter.
- Oshyan
Hi Oshyan,
I'm sorry. "Massive" was a poor description. It's just very hard to explain what
I'm after. All I can say is that I want something that looks more like the last
image I posted.
Anyway.... I think I might be on to something now. I played a little with the
snow function and it gave some interesting results and it looks like it can help
getting me in the right direction. I'll post the results when the build is finished.
Regards,
Terje
I'm curious :) Is it finished already? ;)
Yep. It's finished, but as a I said.... this still isn't what I'm after, but
I think it is a step in the right direction. I will at least test the snow
function a little more.
There is a problem however. You see that straight, ugly line in the
middle of the terrain? I don't know what that is and it didn't show up
in the low resolution build. Any idea on what that might be?
Regards,
Terje
That looks pretty cool!
Where's the .tmd dude? ;)
I could check the line then, but I from my head I think it's the cutoff setting in the snow macro.
Yeah. It was the cutoff thing ;)
I can't see any option that may help getting the line smoother.
For now I just made the snow from the bottom to get rid of it.
Regards,
Terje
Don't forget the .tmd ;)
Here it is ;)
- Terje
Thank you for the preset. I certainly never would have thought of using the Snow Node to flatten out parts of the mountain face. Of course i had to tone the size down to 2048 because i ran out of memory and it still took an hour to render.
No problem ;)
I just imported the terrain to Terragen and did some tests. I got some
interesting results and I think I'll try to finish this project. It's been a while
since I've played with Terragen anyway :P
Regards,
Terje
That looks quite nice!
- Oshyan
It does look nice. It certainly has the beginnings of what could be a fantastic looking image.
Simple, but cool WM2 setup Terje. The use of the layout generator is clever. With some copy/pasting and rotating of the current vectors you can easily extend your terrain a bit further.
The TG2 render looks promising :) I guess you used a mix of the snow mask and normal surfacing for the snow?
Cheers,
Martin
I always try to use the layout generator. It makes it a lot easier to control the basic shape of the terrain.
Yep. That is correct. I used two layers of snow. One standard and one masked with the flow map ;)

Did you mean the snow mask from the snow node? If so.... no. I didn't. I tried using that, but it looked like crap.
