I made beam particle system, (laser weapon) but the beam never disappears, just hovers in space. I need id to gradually disappear over 0.3 seconds or something like that,
Settings i have:
Emitter duration = 1;
Emitter loops = 1;
Any ideas ?
Hey semtexzv -
How are you calling the emitter and beam’s source and target? Are you passing a hard value in or through a Blueprint connection? From your description the beam emitter may not be the best way to go for the effect you are looking to achieve. You may want to use a standard rectangular aligned particle sprite that moves from point a to point b controlled in Blueprints.
Let me know about your beam though and I will look further into this for you -
