For stills, I am learning, and really liking ZBrush. It’s a completely different workflow than a traditional 3D app, so it’s not for everyone. And it doesn’t do animation. It can create great art quickly. It is not a 2D only, app, as you can build and texture 3D models, but at that point, the similarity to traditional 3D apps ends, at least until you hit the render button. Then it can produce renders that are very nice.
I bought ZBrush, because I’m like you. I wanted to create some great-looking stills. It’s ‘possible’ in A:M, but it’s so much faster and easier to do the same things in ZBrush, with the provision that you are equally experienced in both applications.
I’m also in the same boat as you, in desiring to do animation as well. I’m considering LW, Messiah, or a combination of the two. In my case, I actually own LW 5.0, so I’d be dealing with the upgrade pricing.
I would be interested to read what others have to add to this discussion.
(just joking, you’d probably get in trouble over that one)
