Blend Inverted Masks

[ChuckRT]

Hi there, Is there a possibilty to blend multiple inverted masks? What I'm trying to do is to create different masks using ID Channels from Vray, I figure it out that it only blends masks from pure white to black as its normal behaivior but if I invert them to my selection each mask blocks the other one.

In the attachment are the masks as I try to use them individually and the ressult combined, also an example of the normal behaivior on the background that I intend to achieve but inverted.

Sorry I forgot to attach the images, hope that this example show my idea of what I'm trying to achieve

Hi,

Perhaps this method will help you. A normal layer works like a mask:

This method also allows you to mix several masks in Multiply blend mode.
