Hi
I found an issue in the particle system when the engine delta time comes to big values for example from 0.03 to 0.4.
Observe movie what happening with particles:
I also created a sample project where this issue can be easy reproduced:- start the gameplay
- press and hold “Z” key to emit particles
- press “E” to destabilise delta
- observe the issue, some particles are teleported in the far distance from the character and some particles are reverted back.
This issue is really annoying when You want to create a particle effect which returns events from collisions.
I checked 4.6,4.7 and promoted branch(4.8) and I was able to reproduce this issue with my test project.
If you can’t make repro because you have “NASA computer”
just edit MyCharacter blueprint and increase iteration counter in the for loop connected to “E” key.
Anyone has an idea how to fix this? Or where should I start.
Regards
Pierdek
