Hey, happy new year by the way. I wanted to go about making a simple scene where a laser beam hits the surface of a wall/plane and the particles where the point where the beam hits doesn’t begin to continuously spread out. My questions are 1 how can i control those particles after hitting the surface and 2 what would be the best method/ render type to use to make the laser beam appear more solid in a sense. Kinda of like something out of star trek where they fire those phazer weapons.

If youn are trying to make the particles disappear after they hit the wall, what you could do is create a collision event then write and expression that states that if the event occurs then the each individual particles life is 0. Whith this you can also control each individual attributes and make them do what you want with a few simple expressions.

Or hook them up to a PP Ramp:)

now… how do I do this:)

hi..

1 setting a collision with die enabled should end the particles being spread.
2 for a continual streaky look, try to emit the particles with the cycle emission and a volume with directional emitter. also make the steaks longer. at the render time make the multipass to atleast 16 with a blur to minimum of 1.5 that should give you the look of a laser.
