Draw world during the visualization

Hello, is there a way to draw the world volume during the visualization? I’m interested to get photons out of the world but, as you can read here Getting particles out of the world I tried more codes, but I can’t get them. Then, I would like to see by visualization if there are particles out of the world (i.e. it’s just a problem of the code) or really there aren’t particles out of the world). It means I need a way to see the world and trajectories ot of the world (if it’s possibile to do it).
Thank you

Somewhere in your code, or in a macro file, you must be making the world invisible. Remove that or

/vis/geometry/set/visibility <world-logical-volume-name> 0 true

Thank you @allison it worked
