@ LordWexford: Tne registered version of Terragen lets you build and import bigger terrains, which means a lot lore details in your scenes, plus improved anti aliasing, plus bigger renders ( = 100% more details in your final renders.) The next version of Terragen , TG2 will be a lot like Vue, with import of 3d geometry, multiple lights, displacement mapping, subsurface scattering, import of Xfrog plants and so on.. Terragen is a fantastic program, not to mention it's the most photorealistic landscape rendering app you can get. But right now, I'm really bored with it, as all of the fantastic features I mentionned are yet to be implemented. Now Bryce: Yuukkk!!! Ugly renders, bad imports, most unfriendly user interface, very complicated yet powerful material editor, great terrain editor. Nuff said.
