Please could you explain to me how to apply a terrace effect to a selected range of height ?

For instance, how to apply terrace effect only to the lower part of my terrain ?

I hope you understand my poor english  :?
Thanks,
Olivier

Hey Oliver,

The Terrace device has an effect mask input, which allows you to control where the terrace gets applied. So here's how you would make it only terrace certain parts of the terrain:

Take your terrain output (from perlin noise, or whatever), and plug it into a splitter. One wire from the splitter should go to the terrace device, another should go to a Select Heights device. The output of the Select Heights device should then go into the "Effect Mask" input of the Terrace device.

Now open up the Select Heights device and set it to whatever height range you want terraces to appear in. Viola!

PS: You can also use this technique for different purposes, like you can use a Angle Selector to only terrace parts of the mountains facing a certain direction, etc.
