I don't know why I want everyone to conform to my will. It's a good thing I'm not in a position of power ;)

I used Body Studio because I wanted to render Poser content in Maya, and I wanted to use Maya because of Renderman. What turned me off from Body Studio was the inability to modify Poser animations. To me it would be a winner if you could animate in Poser and modify and tweak the animation it the hosted program. 

Another thing I didn't like was the sluggish viewport caused by multiple copies of extremely large textures. Things improved if I scaled down the texture / bump maps. I don't understand why a new shader network (as it's called in Maya) was created for, say, the forearm and the thigh when they use the same texture (mil 3 and earlier).

I'm sure I've tried every Poser to Maya plugin out there except the Greenbrier plugin with varying degrees of success. For the longest time, my favorite was Trinity4Maya but it was beta for three years because the developer had a personal crisis I guess, and their forum disappeared two months ago.

Independent of that, rigging Mil3 characters in Maya is a little difficult due to their exorbitant poly counts. I have had incredible success rigging Poser 2 - Poser 4Hi, Poser 6, Mil2 characters and mild success with V4. All these other characters work so much easier because their poly counts are much lower and / or (in the case of Poser 6 and V4) their meshes have few or no triangles.

That's when I started modeling subD humanoids and I've gained a huge increase of rendering speed. If there's anything that I must have, I just import it using the standard dialog and connect the texture maps in the normal way, which takes no time.

It's really cool that you get paid to play with these programs; in that case this is prolly a good solution. I'm an aspiring film guy and flexibility is very important to me.
