It's a 3D modeling, animating and rendering program.
I hate it. I used it a while ago for about 2 weeks and found it very complex and confusing.
Maybe I just didn't take my time to get used to it.
Cinema 4D is a lot better in my opinion.

Yeah. I like it because I'm getting trained (Notice that the computer is not mine). I agree that it is VERY different from most programs, but if you get used to it, it is just fine.
