I'll just pop back to address something that jura said earlier...

"If Poser and DS is budget rendering SW,why you using? Or why you rather don't not build yours own base figure ?"

Poser and DS are budget software. There's nothing wrong with this. Why? Because I love Poser, It was my introduction to 3d. I enjoy making stuff for and with Poser and I've spent a great deal of time learning how to use its less than obvious features. Poser is incredibly deep once you strip away all of the surface make art button aspects and take a look inside its files, the set up room, the cloth room, etc. Kinda like why Wings is my favorite modeler even though I have software that's more fancy (as box modeler Wings will give any other modeler a run for its money, modo included). I have made my own figures, although I don't think robots or tentacled creepy crawlies or articulated plants would look as good bent over a couch as V4 can (not to mention that the idea of trying to model as well and rig something even remotely sophisticated as V4 on ones own is absurd, like Joe said no need to reinvent the wheel. Nice to know how to put some new rims on though.
