Hello Alexi, It looks like G4ParticleChange has its own ProposeWeight method to change the parent weight (I'm not sure why it doesn't use the weight set through G4VParticleChange::ProposeParentWeight). Perhaps you could try G4ParticleChange::ProposeWeight ? I guess you'd have to cast from G4VParticleChange to G4ParticleChange if necessary.
