World Machine 2 Alpine Terrain Help

[sjefen]

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?

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.

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.

Hi Terje,

How are you going with this?

Cheers,

[dhavalmistry]

yea I am looking forward to the terrain as well...

[sjefen]

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

How about this?

That looks pretty damn nice Martin!  Can you also export the erosion layers as masks?

Of course, default workflow for me

[Henry Blewer]

World Machine will allow multiple types of masks for each terrain type. It is quite powerful, but I prefer Terragen 2's methods.

[Goms]

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?

Terje

[dhavalmistry]

what you need is "Sharp Ridged" as the style in advanced perlin node
