Daz 3D has made three programs free for the remainder of April. These are for the Pro version, with serial keys that would cost over $800 at the retail price.
To download go to the Daz 3D website
, you will have to register an account, then buy the software (for free) No credit card of payment information is required.
What you get:
Daz Studio - A 3D character/scene creator, that can create some nice renders easily. You can also use it to render interior scene, or even outdoor (but Bryce is better for Outdoor)
Bryce - You can use Bryce to create an outdoor landscape scene , and even place the characters you pose in Daz Studio inside your outdoor setting. You can also use Bryce to generate heightmaps that you could then import into Unreal Engine, Ace of Spades, or any other Game engine that uses Heightmaps for terrain.
Hexagon - a 3D modeling application, that allows you to create 3D models in an intuitive way. Its one of the easiest ones that I have used (even easier than Wings3D) and seemed to have a good amount of power behind it.
(Maybe if I learn patience soon enough and manage to model something decent I'll post a screenshot.)
I think it is worth the few minutes it takes to register and get the software.
Update: As of 5/4/2012 it looks as though the Saz Software is still free, they haven't given a expiration date for it this time.
