Laser effect?

Did anybody know a way to make a nice laser effect?

Point your fingers and say “pew pew!”

You might have to be more specific. A real laser or a sci-fi laser?

I do a very simple, continuous laser with a straight (and local) beam of fast particles with an optional glow colour.

Might or might not be what you want.

a sci-fi laser, will be my ship weapon…how do i use glow color on particles?
