I created a mirror box using six planes, put a few spheres, a light, and a
camera inside it, and expected to see it going on "for ever", but was
surprised to see it going for only 4 reflections.  Is this normal, or is
there a setting I'm missing?

Thanks

Add - global_settings{max_trace_level n}

Where n is the number of levels of reflection you want.

1/0 apparently....

Rick, as well as the docs, take a look at Warp's VFAQ
http://www.students.tut.fi/~warp/povQandT/
for this and other common problems/misconceptions.

Dialling the reflection down to .95 makes it max out on 109 levels.
