Smoothing Polygons

 From:  Pozero

Is there any software I can use to ADD polygons to my 3D mesh?
Here are 3 pics of my 3D mesh tail. On the first pic, tail is in zero position and on the other 2 pics my mesh is deformed because of less of polygons.
I create 3D tail in MoI and exported with highest polygons level possible. Than I rendered it in Poser 7 (smooth polygons checked) and here are results...
How to solve this ?
