This took 52 min on a Pentium 200Mhz,
When I turn on Reflective caustics, it takes FOREVER!
Also, does anyone know why all objects turn black when
the MAX_TRACE level is set less than 4?

Hmm, it tend to take time... :-)
I have a image that is illuminated only with reflective caustics..
I plan on doing the old Disco-ball sometime later.. :-)

I prefer to trust ADC bailout...
I'd guess that there are too many walls on the objects, the beam has to pass
through both sides(2) if they are hollow, 4, and the camera, 1 ....

Reflections on transparent objects are a pain anyway; when you use
reflective caustics, it just makes matters worse. I believe the photons get
reflected back and forth in the object. I encountered the same problem with
a whiskey glass scene I'm making. I used ignore_photons on the glass, which
helped.
BTW, I really had to use ignore_photons because otherwise the glass would
just be bright white. I think this is because the thin walls of the glass,
the nearly-coincident surface problem.

Simple can look so good. Very clean.
Yep, the max_trace_level needs to be high enough for transparent objects
especially when reflection is used, dependant on the number of surface
faces too (inter-reflection). The amount used in this isn't really
enough to warrant use of the caustics of photon map reflection, I would
think, anyway.
