Thanks!
@ PG:
I could do a walkthrough if I hadn´t been so stoned when I made this.
No, in fact you don´t need a walkthrough, because it is really simple. I just found out that most of the things I did arent really necessary.
I used a "voronoi 3d diff scalar" as input for luminosity and displacement of a surface layer.
Now comes the interesting part: I used a power fractal as "scale" input for this voronoi-box.
That´s it. Have fun!
@ Oshyan:
Thanks again.
I turned off shadows and atmosphere in order to save rendertime.
I also like this black and white REM-look.
But I am going to make something more like a sunlit landscape.
Maybe someone else is faster than I am, now that my "secret" is out.
@ all:
I don´t think I am the first one who did this very simple trick, but I did it without help. If you found it here and like, it, say so!
Best Regards,
Jan
