I just got a copy of Fractal Terrains and finally downloaded Wilbur [really, finally].
I've wanted to mess with both of these for years and just never got into it.
I'm trying to see if I can use Wilbur to help me with a commission I am going to be working on.
I'll post some more later after I try a few things. There is a lot to learn about Wilbur and all of its features.
And sadly, i sometimes learn slowly.
All this relates back to a post earlier in this thread, a topo I worked on some years back for a client.
They're now ready to do more work on this world. Should be interesting.
Edit - might as well repost those pics...
