Hi Tsukasa,
I have updated my PhysicsList and got the photons to interact with my sensitive detector. Also I have updated my RunAction and TrackingAction according to the example B4c.

But, the output shows 0 energy deposition.

I will be grateful if you could have a look and give me some suggestions.

Thanks.
