Coming soon, World Machine and Terragen 3. Any one here using Terragen ?
I do! made a few images with it on my deviantART: http://con-struc.deviantart.com/
havent really gotten around to figuring out how to use masks rendered out of WM as surface layers in terragen yet, they always seem to break on me..
I don't. What can Terragen do that WorldMachine can't?
Purely in terms of terrain creation, WM has much prettier outcomes IMHO, what with the erosion node and all, but Terragen can, if you go out to such a scale, render out the planet's curvature into the terrain, (which if you do enough research into map projections turns out to be quite important http://www.youtube.com/watch?v=2lR7s1Y6Zig
) along with protusions and holes in the terrain (because of WMs heightmap limitations.
It really depends on what you need to do as to which would be the better option, but for me using a rendered heightmap from WM as a foreground and Terragen power fractals as the BG terrain seems to get the best of both worlds.
EDIT: if i may, a comprehensive World Machine <-> Terragen tutorial series would be fantastic
