Can I animate a model made in ZBrush? I'm new in game modeling and animation, and I really liked how ZBrush works, but blender is better in animation, much easier, but too difficult with modeling.  

Can I animate a model made in zBrush?
If yes, how can I do it?.
Yes, you can, here is how:

Export your model from zbrush(id recommend a .obj).in blender you can open the .obj useing (File>Import>Wavefront Obj)

Now your model is ready for animation.

Note:
In zbursh it is important that you do not export a raw sculpt, since that will not work for animation in any software. Always retopoligize it.
