DAZ 3D
I feel like I robbed a bank last night while installing DAZ Studio Pro, Bryce Pro, and Hexagon. They just kept giving me more free software!
Anyways, this is software for 3D content creation, from modeling to terrain and texturing. Seemingly pretty comprehensive. And they are giving it all away totally FREE, so I recommend picking it up if you think you'll ever use it.
Also, make sure to access your access to DAZ Studio 4.5 Pro, which will give you an account on the website with 4 extra copies of the software to install anytime, anywhere. This means even if the software starts selling at $800 again, you won't have to worry about losing your copy.
Anyways, hope this is useful for someone!
