Hi @rapatski,
I want to achieve a similar effect to the linked poster – a kind of abstract terrain map, with random areas or “countries” which would then have a specific pattern applied.
For my code I have adapted an example with Perlin noise but it doesn’t really do the trick (randomising the params is just for me to see how it changes appearance). However, I see here that Perlin noise has been used to a kind of satisfying effect.
