Hi all, I've tried this:
Rendersettings: Recursion Depth: 2 Threshold 10 AA 0 Threshold 100 Undersampling 2x2 Threshold 50 AO-Effects OutputScale 0,2x0,2 No Postblur Renderspeed is ok :-) Matthias ----- Original Message ----- From: "Mark Heuymans" <[EMAIL PROTECTED]> To: <user-list@light.realsoft3d.com> Sent: Tuesday, November 14, 2006 5:10 PM Subject: Re: New Thoughts was Ambient occlusion updated. > > > > > As I mentioned originally , turn down the AA and this > >project renders in no time .
