free program. And teachs you how to do some things. I did the mase first to get used to tools, then I did the plane, You can learn face's, characters, alot of stuff.
And its much like 3DMax made by same people Decreet. You can load images in the background to make the model. Which i think is cool. Its is VERY! user friendly, that is, if you can learn and follow the tuts.
MAKE SURE you start with mase lol. It teachs you whats what.
