vray alpha map problem

Hi,

I am trying to render an indoor rendering with windows and curtains. I am using vray and all of my materials are affecting all channels. When I render it, as an alpha channel I receive full white rendering. My RGB and z depth channels are completely normal. My aim is to use the alpha channel in photoshop in order to put some images outside of the windows. Since my curtains are also semi-transparent it is important to use alpha channel for me.

Thank you for your help
