Transparent areas glow in rla's ???

[RSF]

Hello.
Can someone tell me why rla files get this strange effect when rendered with vray?? Is this a bug? Rendered with scanline this doesn't happen.
I also tried standard and vray materials. Vray materials don't have "affect alpha" checked (althought I tried it also).

Here's the image I get when saving from render window:


Here's the saved rla from combustion:


and a fog applied to it:


Well...I'm just starting using combustion so I meight be missing something but....it doesn't happen with the scanline
Can someone help?

Thanks

Have you tried the newest format for Max-> Combustion RPF?

Yes! I also tried that!
The "Real Pixels" channel seams to have the correct image though.
Nevertheless I don't think this is the way it's suposed to be.
Also the transparency channel appears very jaggy compared to the scanline render.
Thanks
