Particle splitting / Russian roulette

Hello,

Is there an example to show how to perform particle splitting / Russian roulette and assign importance in a complex geometry?

Thanks!

Hello, did you try to modify \examples\extended\biasing\B02 with a new complex geometry? I used that example with parallel importance biasing, I modified the size and the number of cells in the parallel world and I import my complex geometry with a GDML file.
