Are there any tutorials that teach to make anything other than giant f-ing mountain range? all i see on youtube are basic mountainous environment tutorials, which to be honest arent that hard if you have even remotely an idea of what you are doing. I am trying to make a desert area with small hills and a coast. i got the coast down but i cant seem to get the hill-y area in the desert like environments down very well. this is what i was trying to get - No. 1 and this is my attempt at it - No. 2.
I realise this is pretty old but it got me thinking and playing around.
The problem with using noise is it is, well noise Rolling hills have an underlying structure caused by folding.
To simulate this I multiplied two gradient nodes with widths set to prime numbers to create a random looking surface that has an obvious linear structure. Setting them at a slight angle (5 to 15 degrees) creates breakup and some pleasing intersections. I then used a displacement node driven by either a gradient or a noise node (or both) to create something that looks like the results of geologic folding.
Blur and clamp as required to smooth the surface and control heights as required.
