Saving RPF with Vray

I had problems before saving RPF files in Vray 1.09 is this something I am doing wrong or is it a know bug / problem. If it is does anybody know is it fixed with the later versions of Vray.

Thank you.

We have been rendering out using the .rla format. Its the same thing (I think its made by adobe vs the rpf from discreet) and we have not been having any problems. We also do our compositing in Combustion 3.

The trick is enabling the correct g-buffers in V-Ray, I think the g-buffers are all on now by default.
