I don't know how well used RLA or RPF are anymore (I can't get Nuke to see their layers)?
An EXR depth map that covers the scene gives you the flexibility to apply DOF to any object and adjust the focus to any point. As part of a multilayered EXR we find it works very well (from VRay at least, we don't tend to use the standard renderer).
Yeah, but also to base you decision on Vray update coming any time soon. It's been a long wait already, and there is no date that has been set. Could be another year for all we know.
