Multiple Camera Compositingp

Hi, I'm working on a VR template in after effects, and need some help. The basic idea is that there is a 3D scene, and I collapse-transform it into six comps, each with a different camera rotated 30 degrees more than the last. These are then composited and stitched in a 'master comp'. The problem is that I have to copy all the lighting from the scene into the six different comps (it used to be eight in my prototype), as well as any 3D 'illusions' (e.g. camera-reactive particle effects). Is there any way to siphon off the views of six different cameras, all in the same comp, into my master comp? Sorry if the explanation came out a bit convoluted, I'm really tired.
Anywho, I'd be really glad if someone could help me out.
