I apologize in the delayed response. I had since moved on with my simulation, but I have come back to investigate this "bug". I have found that the photons that escape the wrapped volume seem to be extremely near the edges, i.e. the boundaries of adjacent faces, right before they escape.
For example, for a 30x30x2mm box centered at the origin (0, 0, 0), an escaping photon could have coordinates (14.24862431017721, -15.0, 0.9999999999999727) mm at the step just before leaving the scintillator. I could see how this would be problematic for geant to handle. Either way, it is not a problem for my simulation, but just a curious observation. I could, however, see how it could potentially cause problems for others if they do not expect this kind of behavior.
On a side note, I am having trouble interrogating which process was invoked in the stepping verbose class that I copied from the LXe example. I would have thought that "fStep->GetPostStepPoint()->GetProcessDefinedStep()->GetProcessName()" would either return Transportation or OpBoundary, but it seems to return Transportation for all steps. I am pretty sure I am missing something, but I can't seem to figure out what. Any comments on what I'm doing wrong or misunderstanding?
Any other comments would be very much appreciated as well.
