I’m trying to make a straight line of sphere particles coming from the emitter and hitting an object. No matter what I do, I can’t get a single line that doesn’t, at some point, bunch up and spread. I have dispersion to 0%. I’ve tried changing life, size, number of particles, but I just can’t get a single line. ???
WHat am I doing wrong?

Did you turn off air friction and gravity?

Hi ricmorton

What are your particle Velocity and Gravity settings ?

Any screen-shots you can post of your settings or scene, would be helpful.

See pics,... particles with gravity,. ...particles without gravity.

also make sure that the main value (Variation) options, are set to 0 (no variation)

Hope it helps
