Ive just ruined 3 of my render passes becuase of this. Anybody trying changing the multi pixel filtering in 7?, or wondered how you managaed to diable RGB channels when you didnt even tick it off (the check box actually runs right over the width of the render global windows).
the hypershades magical buttons which more offen than not are not where the garphic icon actually is...
anyway enough of that venting.. i came here to ask about why on earth does mental ray render iffs that are completely unviewable or useable in apps like combustion or AE, and only Fcheck opens.. Ive just rendered 13 shots, about 3000 files, mostly to IFF .. now i cant use them! i have to convert everyone of them. ARGH...!!!
Having a bad hair day too! Probably shouldnt rip so much of it out!
