I’m trying to do some smoke trails. One for a rocket weapon type thing, one for the exhaust of a thruster, another that’s part of a bigger explosion, etc. I’ve been using particle systems and the problem is that the trail just instantly disappears when the emitter goes off the screen.
I know about setting the bounds for an emitter, but that’s not the problem. For example, a rocket moves very quickly and I want the smoke to linger for a few seconds, even though the rocket is very far off screen.
Is there something other than a particle system that I should be using? All I can imagine is some kind of smoke puff actor that I spawn hundreds of to form a trail, which would be prohibitively expensive.
