> 4, 4 // number of sources for each axis (above). integers only
So low! I generally use 17, 17 myself. Maybe I could go lower if I used
jitter more often, but I still recommend using higher numbers than 4; the
jittering with such a low number probably forces otherwise unnecessary
anti-aliasing.
Of course, with such high numbers it's very important to use adaptive (so
that you don't actually shoot a full 17x17=289 shadow rays); adaptive 1 has
always worked best for me.
Finally, I also recommend using a number which is one greater than a power
of 2 (3, 5, 9, 17, 33) because these make the most sense with the adaptive
process (See the second picture at
http://www.povray.org/documentation/view/3.6.1/313/ , which demonstrates why
this makes sense).
