I am trying to collect optical photons in WLS and then detect them at the end of it. I adapted OpNovice to my needs, since I had everything pre-made there. I implemented WLS process in physics list and it seemed to work. Optical photons enter the WLS and eventually they undergo WLS process. But I cannot see any secondaries from this process so photons are absorbed but none are emitted. Why is it so?
Thank you, Matus
