360 degree stereo pre-render needed

The problem with a cube map capture is that we need this in stereo and the stereo will not be correct for the sides and rear of the capture with a cube map capture, so we have to build an array of cameras and export each one. I imagine that if we do a 2D scene capture and export each one it would work. I could use some help with what code to use to make that happen per frame with each one and have all of the effects and procedural animation not get broken or be out of sync.

thanks for the help,
