Well, Anim8or wont let use use animated 3d objects because it cannot export animated models in a format db can understand. If your using static models then your fine. Also, if you want to render 3d images to make them 2d sprites (which is what i think you mean here) then it can also do that. You need to animate your model, then Anim8or has a feature to let you export every frame of that animation to an image. Then youve just got to cut and paste them into a big sprite page and set it up with code.
Milkshape is still a pretty good 3d program, especially for the amateur modeller as its very cheap yet powerful and capable of doing the things that most 3d game developers need.
