I have a scene with some objects standing on top of a box, inside a hollow transparent
box filled with media. There is a point light source above, which does not interact
with the media.
If I add a new cylinder object the visible box will no longer be lit up even though
the objects on top of the box are lit just like before. Adding a new box object will
not give this effect, although adding multiple box objects
will. (The new objects are much smaller than the box so they couldn't possibly block
out all the light, especially as the objects next to them are lit.)
I'm using POV-Ray 3.1 for Linux.
I'd be very thankful for any help on how to avoid this problem.

If you post the offending code with your camera and light and
objects we'll have a look.

A wild guess: As you have a transparent box, you might have to increase
max_trace_level (in the global_settings block). This value determines after
how many intersections, reflections etc. Pov stops to trace a ray.
If this does not help, you will have to give us some code to look at, I
think.

Note however, that max_trace_level has no effect on shadow calculations
(they are always fully calculated, no matter how many semitransparent objects
you have between the current point and the light source).

I got around the problem by making the media box larger so that it contains the
visible box as well, not only the objects on top of it.
Thanks for your help!
