Exporting Alpha Channels to Mask Objects in Photoshop

[Anonymous]

Hi all,

I am trying to use cinerender on Archicad 19 to export alpha channels to photoshop so as to mask and edit specific parts of an image and cannot for the life of me figure out how to do it. I can get the background to become an editable alpha channel alright, but what setting do I need to toggle, what button do I need to press, to get material specific alpha channels to display, and better yet, export to photoshop?

I am new to archicad, and looking to produce a rainbow image, such as you can come by fairly easily in maxwell:
