Creating Sand Dunes/Desert landscape

[Alpha Centurion]

Hi,

I'm new here, and kinda new to Terragen 2. I am acquainted with the basics of this software, and I want your help to create sand dunes. I have searched the forums and not found anything of substance, which I can use. Your insight is valued.

And welcome to the forum 

Thank you for your assistance. However, as I do not understand the content of that thread, it does not help me create sand dunes.

I only grasp the basics of T2, and would like some general guide lines.

I think the idea is that you download the .tgc file and take alook at the node settings

Yes 

Alpha Centurion you can put these .tgc  files (clip files) with  "File" (from menu) then "insert clip file" in your project.

It's basically very simple, AC. Make a power fractal, noise = ridges, sized 100/1000/10 or so, displacement of 10-50. Feed this into a second PF, same noise, smaller sizes 2/100/0.5, and small displacement (say 0.5-1), feed this into the first compute terrain, and you have a basic dune like terrain. Add and change from there.

Oh yes, but my problem is that I do not understand what all those functions in the node network are yet.

Kadri, thank you!

Thank you very much for this. It's exactly what I needed. I benefitted greatly from this advice.

Insert the clip file, then connect the bottom node of your existing terrain to the top of the clip file, then replace the connection between your original bottom node and the base colors/planet surface shader input with a connection between the new bottom node and the base colors/planet surface shader input.
