Dear Maria,
I remember there was a similar problem ages ago, when Annalisa was taking a look into Dirc code. The problem was not the material between the two volumes, but simply the edge of the volume itself. In optical properties I remember you could define if a surface was absorbing or reflecting or transparent dwpendently on some flag inthe materials,and the flag was different from g3 and g4.
This is not a answer, maybe you could try ask Ivana if Mohammad does not remember which was the solution at that time. Maybe there is something inthe forum, you could try to search for old Annalisa messages, but I don't remember if the solution was written there.
Hope it could help somehow.
