Some other tests.
A final different image is rendering now.
It needs actually a little more work but i am less and less enjoying dealing with the technical sides 3d programs.
I don't mean only Terragen. All of them (not that i tried all the ones that are around of course).
Maybe i am just getting old.
I had a "the first seer" moment with the first image
The second one was related to the above post if i could use the native cubes with displacement from a little distance too in Terragen.
The render that is going on is similar to this one.
