Hello

Is  there a guideline document on the differences between fine and superfine?

what settings does everyone use here?

I always use fine.

thanks

Super fine is necessary for soft shadows and really long render times...LOL...it really depends on the image as I use a variety of settings myself...more opinions to come no doubt.. ...

Generally with really noisy textures or extremely clean textures with special things like burry shadows or reflections and such, higher antialiasing settings may be usefull. In any other situation, fine is probably sufficient.

I'm thinking like Bobby said...it all depends on what I'm doing so I use a variety of settings.

I use super-fine a lot.
Sometimes I like to turn gamma correction off for dark scenes, like a deep space pic. I dial all the ambience and some diffuse from my mats and make up for the lack of ambience with a lot of source lights.

Fine = You only get 1 ray per pixel

Super Fine = you get control of Rays per pixel. Default is 16 but you can go all the way up to 256 More rays equals soft lights and shadows or less banding in lights or shadow renders. If you are doing a Sword in the Stone type render with visible light you might notice bands in the light with fine rendering. It also hapens in clouds or other objects with partial transparency. Go to superfine and add rays per pixel till it goes away.

well in abstracts fine seems to work fine.

still takes ages to render though (well my perception is it does, now takes 2 hours instead of 4 on as it used to on my old machine)
