Suppressing Alpha output per object in iray

john_babec29f

I do most of my renders in layers (separate render for foreground, bg, ambient, specular, etc...) and then composite after for great control.  However, having a hard time figuring out how to set this up in Daz 4.9 Pro / iray

What I need to do is find a way to render all the objects, but only output alpha for a particular subset of those objects (i.e forground model has alpha on, background has alpha off)

 

thanks!

You could use an ID canvas in the Canvasses setcon (Advanced tab of Render Settings) Or do a separate Beauty Pass render for each object.
