I'm not sure of those scripts ran into the same issues that I did with my beam related tests, but my experiences with them seemed to mirror what FunkySwerve had said at the time, though not for the reason he'd said.
I'd found my systems worked perfectly in SP, but in MP, even on my own computer testing as a server, close to half the beams simply didn't show in the client, and it seemed random which ones were dropped.
It led me to believe there might be a limit to how much vfx info the server will send at a given time, though I never tested it enough to find out what the exact conditions and specifics were.
Hopefully you don't run into the same sorts of problems with those, but if they're going into a MP environment, make sure you test them in MP as well, not just SP from the toolset, to ensure you're getting the effect from them you wanted.
