I've been working on a scene that's about ready for final render, but
one of the things in the scene is a CSG of about 8000 small objects, and
the autobounding is a LITTLE more liberal than it needs to be.. say, two
to three times the actual size of the CSG. If I'm not mistaken, this
means that for every ray that hits that box, it'll have to test against
all of those 8000 objects, even though most of the rays will never hit
any of them. In any case, the middle third of my render just crawls..
anyone have any suggestions for speeding this up? Would manual bounding
help? Is there some clever trick I can use?
