Yes. Just do the various renders in sequence, changing the settings as you go. For example, in outline:
do
` render camera 1
sync mask 2 ` or %0010 if you prefer
` set various things required for camera 1 here
sync
` render camera 2
sync mask 4 ` or %0100
` set various things required for camera 2 in same way
sync
` render camera 3
sync mask 8 ` or %1000
` set various things required for camera 3
sync
` render main camera
sync mask 1 ` or %0001
` set various things required for main render, i.e. camera 0
sync
loop
This is the sort of thing done routinely in things like shadow mapping, bloom effects and so on.
