Hi Chris,
The code will work when added to the world volume. What I needed was a world
volume that was made of rock, with an air pocket in it. The veto is inside the
air pocket, and surrounds the central detector. So far, everything looks pretty
good. The geometry tree is as follows:
"physWorld":0
"physCave":0
"physTank":0
"physMineralOil":0
"physAcrylic":0
"physScint":0
"physInnerPMT0":0
"InnerPMT_body_phys":0
"InnerPMT_inner1_phys":0
"InnerPMT_inner2_phys":0
"InnerPMT_dynode_phys":0
.... (lots of PMTs)
