HELP ! Mental Ray DOF

[3DL]

Here's the problem :

I use Depth of field in a scene, it's perfect with defaut renderer, but if I turn to Mental Ray the DOF simply doesn't work :S

Is there a special setting to tell Mental Ray to render the DOF?

( Mental Ray renders all the 12 passes, but there no blur at all :s )



- : No the DOF setting are not at 0, this is not the problem ;)

Thanks for the help
