Thank you all again !
QuoteOn another hand, it would be interesting to try and get these kind of mountains from within TG
I would be unable to do these moutains from within Terragen : all these blue nodes that would be necessary to use for such an undertaking are all mysteries for me. I still have a lot to learn.
QuoteAre the mountains multiple heightfields, or just one?
Yes they are done of four different heightfields.
QuoteNice rocks too, are they imported?
For the middle and small ones, yes. They are from "the rock essentials" from Blender Guru. The three other big ones (or rocky spur, I don't know how to translate this from French exactly) are made using rock brushes from the same package, I used the one where the camera stands with an image brush displacement painted shader.
