Terrains and textures made with Gaea (Build 5000) :P
I have been following the development of this software quite closely and I believe eventually Gaea will be a formidable adversary to the current industry standard World Machine, but it is a few years out IMHO, that said with Dax behind the wheel .. its coming
If Gaea can fix a large number of bugs and improve the speed of software, I think it will be a very powerful terrain software. :D
