The source is too large to post without compression.
Try this.

Sorry, but this is very hard to work with, all individual meshes and almost
impossible to debug.  It's likely that there is a problem in the mesh
construction, it is far better to have it unified as a single mesh object.

The best I could do is play with max_trace_level.  Each side of the glass
should have 2 surfaces to work properly, so setting mtl to 2 should keep
the top where only the rear surfaces are visible (i.e. 2 surfaces) clear
and the rest of the bowl black (i.e. 4 surfaces), however they are all
black.  Setting mtl to 3 makes it clear.  Again, setting to 4 should make
the whole bowl clear, however it doesn't.  The testing indicates that your
glass has 3 surfaces around the bowl rather than 2, which makes the ray
interpret the inside/outside incorrectly.

Hope this is helpful.

Thank you,
I think that the solution maybe is to change all the 'mesh2' objects to only
one 'mesh2' object with all vertex inside. But, this solution implies to
change the source code of the program I work with. Maybe when I have enough
time...

JSR.
