Hi, i have a problem with my ribbons which follow my particules.
Almost all ribbons are ok, but sometimes there are ribbons which join to 2 or 3 particules between them.
With version 4.12 all is ok. I think it’s perhaps a source particule problem with the 4.14 version.
Any clues?
Hi cocopops,
There is a pretty good chance that what is happening is that the “max particle in trail count” is too low as this takes priority over your “max trail count”. In other words if you are limited to 500 particles and a single trail of particles has 50 particles alone then once you hit 10 trails you can’t display any more even though you have your max trail count really high like 100 for example.
When this happens the particle system will compensate by moving left over particles from a dying trail (when the source dies) to a trail that is supposed to exist currently but can’t because the particle limit has been reached. The result is exactly what you described.
Here is a screen shot of the settings I described for reference.
Just increase this value and that should help. Also make sure that you have “Clip Source Segement” checked just in case.
let me know if that helps,
Ed
HI Ed,
I am working with cocopops on this project.
for your fast answer.
I just tried what you mention but it did not solve the problem.
I just provided you the asset in a simpler version ( 298Ko) for this particles if you want to try to reproduce the issue and I attached 2 screenshots for potential readers if they get similar issues.

Hey Sky3,
I have reproduced this issue and logged a report for it here: Unreal Engine Issues and Bug Tracker (UE-38824)
It seems that the lifetime of the particle relative to the emitter duration was key to this test. I was using default values so that explains why I didn’t reproduce this issue initially.
You can track the report’s status as the issue is reviewed by our development staff. Please be aware that this issue may not be prioritized or fixed soon.
Cheers,
Hi Ed,
Do you know if this bug might be resolved in 4.15 ?
I made a quick fix to solve this issue.

I made a quick fix to solve this issue.
There hasn’t been an official fix made to this issue. It is currently in our list of backlogged bugs. Feel free to post a workaround if you have found one that is reliable.
A quick workaround you can try is to set the “Max Frame Distance” located in the “spawn per unit” module of the trail effect. Set the value to something larger that the distance the ribbon travels per frame and less than the distance that the trail has traveled from the source. This will tell the spawn per unit to stop spawning particles if the movement exceeds the value, which in most cases is whats happening when the ribbon source is lost and reverts back to the origin
I guess my Fix is reliable but we have no access to some regression test to evaluate a fix link text
