Size of "render squares"
When rendering a scene -- draft, final, whatever -- how big do you typically set the "render squares?"
I often use 16 pixels because I believe in many threads doing a lot of "little" work. But on machines with only 4 cores (as mine currently has) it is painful to watch no matter what size. ;-)
Does the scene content affect your choice? I found that the render will often work extra hard on hair and such; thus many cores with a small "render square" lets several processors chew on producing the hair instead of having one big "render square" cover everything and leave all the work to a single core.
I really need to stop procrastinating and build my 24 core server! I can hardly wait to see Carrara fly on that.
