syrianrue, 

I highly recommend one 3D app that hasn't been mentioned yet:   Carrara. 

It's also sold by DAZ3D, and does it all....I think it also can import Poser content (?)

I don't use Poser, but do use Carrara, Bryce, Hexagon, Blender, C4D, ZBrush and VUE. Each one does something well and usually better than the others, and all are fun to use.  

Carrara is great for animations.....very easy to use, tons of presets, including terrains & skies. 

Bryce...I started with it around '90....paid $300.....it's free now......it was THE 3D app at the time, and though it doesn't have polygon modeling,  you should see what others have done, and still do with it......some use it exclusively. [See Bryce5.com

](http://www.bryce5.com/categories.php?cat_id=15&page=2)Hexagon (free at DAZ) is a very good modeler....very underrated. 

Cinema4D IS a wonderful app....but extremely pricey now. Great for modeling,
rendering, animation. Best gui, imho. 

But I also take exception with a previous statement (as did shvrdavid),

"C4D is 1000 times faster easier better then Blender."  As much as I like using
C4D,  Blender is incredibly powerful, and very worthwhile trying out.

Blender does Pixar-quality modeling & animation........see the Sintel video
done completely in Blender (and 2yrs ago with an old version!).

I like Blender so much I created a website just to help others get 
up to speed with it with links to many tutorials and Blender websites.

ZBrush! =O
~$700 to purchase, but all the upgrades are FREE, and they
bug you to upgrade.....incredible!  

It's much different interface & tools, but fantastic. 

Lately am diving into VUE11 for realistic skies & terrains......SciFi animation.
I avoided it for a long time because it runs relatively slowly, but the results
are worth it.  

Lots of great 3D apps out there to choose from.

Here's my YouTube channel if you want to see what I've done with each app. 
Nothing too complex.   

Good luck. Have fun. =)
