Aye, I think I follow what you're saying, Incarnadine. The reason this came up tonight is that the above render is already as premium as I need it to be. Turning on DOF in Bryce would drive this file (and PC) to it's knees. I can't afford 3 or 4 days of downtime right now... It's not a necessary thing just yet, but I needed to be able to automate the process for use in AE later this month, and the ring was just a test for that, really. Then it got out of hand... I had hoped to use True Ambience on this one, too, but with all the reflections/refractions and ridiculous materials the render times were just preposterous... I'm off to try rendering the ring in Maya to see how that turns out...
