All I do, is turn off antialiasing. Up to 500% increase in render speed, with very little quality hit. Most of my time is spent test rendering, why wait for a little quality increase?

That is a great tip...this is refering to Bryce 5 right? Good tip. Sharen

dON'T HAVE b5. iT'S PRETTY UNIVERSAL TO 3d, but B5 in particular, I guess cause it's a raytracer....

I'm using B4 and have found that there is a MAJOR difference in the final quality when using antialiasing. I don't normally use it during the "draft" stage when working but sure use it for that final render. I've compared final output of my stuff both with & without antialiasing, and without it, all the details that I put so much time into just don't come out right. I guess it depends on what kind of pic you are doing.

Exactly. It's for jaggies- the diagonal lines (which computers don't make straight they stairstep, if you remember in the low rez, low color days of yore) and colors of high contrast- So if you hve diaganol lines with high contrast- you'll notice the diff, but only at those spots..

When you want to use some of the "new" special render options you can only do this in Premium mode which is slower then molasses in December even on PIII 600!

Does anybody know of a bryce5 benchmark and tuning tool?

OK I found a benchmark tool it is at http://www.planet-3d.com/bmark.htm
