Since I've been to Ireland for a week, I was inspired to try and recreate some of the landscape. I shot a lot of sea/beach/wave photo's, so I might want to give those a go with the painted shader and stuff.
But first some hills...
First image is a real photograph, second is a render. Photo is the closest thing I could find, didn't shoot a lot of hills it turns out.
The render is currently rendering bigger, soon to follow.
Everything is procedural, even the path. I decided to try the intersect underlying effect. So a green surfacelayer with perlin billows displacement favours rises, and a sandy surfacelayer favours depressions. A small powerfractal on the grass layer gives a TG 0.9 kind of look. I tries grass populations, but those didn't turn out very well.
