Has anyone successfully used blurry reflections? They seem such a hit for renderring time that its difficult to make the necessary adjustments. I've noticed a few posts where this problem is mentioned.

mmh, in fact, blurry reflections are enough slow, i think that we can say at this pont that is a real problem and not a suspect... BTW, i use it decently at fast quality, but at best or good it's really slow. -TOXE

Playing around just a little it seems that flat surfaces are much faster than curved.

yes, it seems... But the question is enough blurry;-)

this took about 3 hours to render at this resolution... with GI, radiosity, ray-traced DOF and blurry reflections at good quality. Some have said that's too long... but, I guess I got used to waiting for Bryce renders... so it seems like a decent wait for all of those effects at the same time.

I found blurry reflections to be excruciatingly long on anything but the most basic of scenes. Even small test renders are long. Has anybody used the ZMorphics blurry refection for C3? How do their times compare? Seems like I heard they weren't developing any more. Maybe if their plugin is way faster, they might update it for C4. Patrick Tuten

Patrick reminded me I have Zmorphics for C3. This picture is a C3 rendering with blurry reflections by Zmorphics. Time about 5min 30sec

This picture is C4 with good quality blurry reflections. Time to render 6 min. Pretty close. Maybe the code is similar? The same? (The Zmorphics plugin has more variables to control and I was able to make some much faster renders with lower quality settings. Difficult to compare) Zmorphics was also slower with curved surfaces and very slow with multiple reflections; the same as C4
