My brother and I were having a talk about why we've been using this freeware program for a decade.
We've always found Anim8or to the program we use the most. Even considering the fact that when we make our games we do everything from modeling, music, to programming without help.
The only other 3D program I use is Maya, but I don't model in it, I just use it for animation because it is very easy to run it's FBX animations in Unity. But my models are always made straight out of Anim8or.
My brother added that the maya forums have an unusual feeling to them, since he would ask about if Maya had a tool, basically he tried to describe An8's cut edge tool. The reaction he got from the people there was basically : "Why would you ever want to do something like that?" Without actually addressing the question to solve it as a problem.
From what I understand, people who primarily use Maya treat 3D modeling as digitally sculpting things. Where as, at least for my brothers and I, Anim8or let's us make models by what feels more similar to making a drawing but in 3D (a-la our collectively most used tool "add-edge") or otherwise a digital form of origami, a-la cut-edge tool (our second most used tool).
Maya on the other hand, as far as 3D modeling, seems to require some rudimentary understanding of sculptural principles.
Besides how much I appreciate how An8 simulates 3D drawing + Origami, here are some other reasons I love it personally.
1) It's a tiny file, that can be installed like nothing.
2) It loads up pretty much instantaneously, even on lower-end computers.
3) The Arc-Rotate tool. It can do everything you need a camera to do and is easy and intuitive to maneuver.
What about y'all? Why do you love anim8or?
