Z-depth problems?

[neods]

What is the best/fastest way to get a proper z-depth pass rendered out that can be used in etc. after effects. I used Cinema4d before and now that i'm testing out vray is there a good way of getting z-depth easily and efficently?

thanks

you need to check the gbuffer channel for z depth and render out to a format which supports an imbedded z depth channel like rpf or rla.
