<< Its a shame that so many different softwares are needed to do these things.

Even you want stay inside Moi : today you will not have "material" and / or "Texture" (bump etc) for realistic photo rendering! ;)

a cool free one (maxi 1920 * 1080) can be Simlab Composer Lite! ;) http://www.simlab-soft.com/3d-products/simlab-composer-lite.aspx

This is a simple surface 3D inside Moi exported to SimLab in OBJ format! ;)
10 seconds for make the form (thx distort curves) : 1 second for export : 3 seconds for render (depending of what material, texture, bump etc...you choose :)
