compiling characters and stuff

[crackhead]

so i was just wondering about compiling characters as ill be done with mine soon. so do i need to model and skin the mouth and teeth and eyes? do i model the eyes with just a white texture covering it and qc eyes does the pupil and the coloured bit?

also for the facial animations is that one vertex animation for each shape you need? so like your model in the ragdoll pose with just the mouth shaped in different ways?

also is anyone here experienced in xsi in exporting animations? none of the animation smds i export work and i dont know why.

thanks in advance.
