BFC wont help ray tracers.  Just because a surface isn't visible from the
_current_ camera position, doesn't mean it doesnt cast a shadow or a
reflection.  Ray tracers need those backsides.


I was talking about rendering engines like LDLite, MLCad, L3Lab, etc.  You
are correct that BFC won't help ray tracing.  The big thing that would help
ray tracing is eliminating completely enclosed faces/studs.  But that's
another thread :-)
