[Gate-users] [Gate 7.2] Issue with optical photons

[Володимир Родін]

Hello all,
I simulated PET with scintillation crystals.
When I executed project in Gate 7.1 I received this picture (Img1)
Same project I started in Gate 7.2 and received  almost the same picture,
but without photons (Img2)
Difference between compilation processes - version of Geant4:
7.1 - Geant 10.01.p3
7.2 - Geant 10.02.p2
I use GATE_USE_OPTICAL  *ON *for both versions and I have  surface
messengers for my volumes.
I  am working with Geant 10.02.p2 now and amn't see any problems(IAllView).
Best wishes,
Volodymyr Rodin
