Fixed it by going into Required > Rendering > Max draw count, and raised it from 500 to 1000.
So yes it seems it couldnt spawn more until the old ones died out.
Thank you.
I’m trying to make it so that the particle spawn rate (or spawn scale) is increased for 1 second, then goes back to normal. I tried with and without a timeline but this issue persists in both.
In the first picture the particle works as it should (The mesh with the particle is moving from right to left), but in the second picture another ‘wave’ sweeps across from left to right after a small delay.
Does the second picture behaviour happen after the first’s?
The two pictures look like really long particle trails. Have you tried adjusting the particle lifespan? You may be hitting up against the limit on how many particles you can spawn at once. The “wave” then is the emitter briefly halting on spawning new particles until some old particles die off. You could try turning down the particle lifespan to see if the wave disappears. Or increase the maximum particle count.
