I have a work around. I create a switch in all my shaders that have alpha, put an ao node in, plug in the alpha to its opacity.
Then in a new partition I set an override to switch the switch, and change the settings of the nested ao globally or partition wide. Essentially you are storing the ao shader with opacity alpha within the shader then activating it via override. Hope it helps! I have tried it on redshift, Arnold and mental ray. --- Original Message --- From: "Chris Marshall" <[email protected]> Sent: September 30, 2014 5:15 AM To: "Thomas Volkmann" <[email protected]>, [email protected] Subject: Re: transparency and ambient occlusion Thanks, I think I knew that one already! Doh! It's not quite doing what I want though so I'm just going to not have any AO after all. Thanks anyway.
