Sand Dunes

Hello guys - i want create Sand Dunes like in this Picture:

I startet to create a simple Perlinnoise in a Point-Vop to Displacement geometry along the normal.

Now i need a control over the Luminance/Contrast of the Noise Perlinnoise with a Ramp Parameter to set this sharp Edges at the top of the dunes.

Do you guys think this is the best approach to creating this?

Using noise is at least the most common approach for generating landscapes.

  • Scale the position vector down so you can still use sane values to control your noise.
  • Use 'absolute' to get sharp edges and 'complement' to put them on top.
  • The second noise just varies the overall altitude.
  • No need to displace along normal if you are working on a flat grid. Just set the height value directly.
