Node Questions

[ProjectX]

I'm trying to create a crop terrain shader (as a way of making much more natural canyons), but to do this, I need to know exactly how the get altitude function works - what does it output? A colour? A scalar?

If it outputs as colour or vector, is there anyway to displace a terrain by this?

I think that's all I need to know for now, thanks for any help you can give!

Edit: while I'm here, what setting in the alpine fractal generator sets the distance between the mountains formed (what I'm looking for is vast plains, with mountains in the distance)

Edit: Nevermind, I've sorted it out, used a "Get Y as Scalar" from the "Get Altitude" Node and it works. Alpine question still stands

The "Feature scale" is going to give you larger, further apart mountains. If you don't adjust Displacement Amplitude then they'll also be short and broad. Adjust equivalently to scale both mountain base size and height.

However if you just want to maintain the same size mountains and separate them by plains I would suggest instead using a Blend Shader with a large-scale Power Fractal.

Ok, thanks for your help!
