I remember that scene when someone was trying to figure out how to make it work
(i.e. complete before their great-great-grandchildren are born) in MCPov.  I did
get it working, but it wasn't the whole scene, just the doors and walls.  The
answer had to do portals and making sure that the container sphere wasn't too
large.  After that, it started to converge reasonably quickly (instead of the
wait 20 minutes, see single bright pixel appear, wait 20 more, see it
disappear).    Anyway, isn't that bleed through more of an error bound and reuse
of samples issue as opposed to depth?
