The rendering from Tim shows some artistic driven and clever combination of other techniques as a different approach to brute force GI. He doesn't used FG or photon mapping or IP. So it doesn't reflect mental rays capabilities in photorealistic rendering but instead a other way around. Render the scene in arnold or maxwell with AO only and it will look the same.
Of course no one would go the AO-only route to achive photorealism. So I think it shows a different way to test and play with the possibilities we have as artists, rather than mental rays capabilities. sven From: [email protected] [mailto:[email protected]] On Behalf Of Vladimir Jankijevic Sent: Monday, February 25, 2013 20:31 To: [email protected] Subject: Re: Octane render I think it's still worlds apart from anything that comes out of Arnold and/or Maxwell. Yes I know it's only envAO, but still. I'd rather let it render twice the time to have a really beautiful render than have to fake all of the illumination and get something like this. Oh man, I'm so happy I'm not in Mental Land anymore... On Mon, Feb 25, 2013 at 8:04 PM, Tim Leydecker <[email protected]> wrote: Thanks for the hint to unified sampling! Nice.

Dof could even speed up your render due to the more clever sampling scheme. I usually go with mia-bokeh, stopped using post-dof quite a while ago. Similar thing with motion blur, it's a different game with unified sampling. -- --------------------------------------- Vladimir Jankijevic Technical Direction Elefant Studios AG Lessingstrasse 15 CH-8002 Zürich +41 44 500 48 20 www.elefantstudios.ch ---------------------------------------
