I've made Environments for all of my movie scenes. For example one environment is a neighborhood with a bunch of houses, trees, a road, some traffic STOP signs.

Then in my scene i will have characters like James, or V3 based or M3 based with clothing on.
Seems poser makes a movie slower b ecause there are too many objects that need memory. 

For example if i MAKE MOVIE using display mode and the display mode is SHADED, if i have characters + eenvironment , the making process is like 5 seconds per frame or more but if i do a movie with just the character then it's much faster.

then if i were to use Low poly characters and that's it, then that's super fast. 

So if i want V3, M3 based characters and i want it to make the movie fast( in display mode SHADED), i should make my movie with no Environment and then just use a BG picture layer in Final cut?

That means I have to give up all the Camera techniques that would be possible if i had characters in environments. For example, if i do camera rotations, the cam would go around the character but it wouldn't make sense cause the BGpic is static and 2 dimensional so it won't change.
