I did some research and found time dilation. But if i set my blueprint that has the particle system to 0 time dilation the particle disappears. If i set the time to .0001 the particle freezes.
Why are the particles disappearing when time dilation = 0?
It’s not quite clear what your desired functionality is.
Could you provide a video please?
I would like to have a particle system freeze. Then later i would like it to resume playing.
The particle has its own blueprint. I can dilate the time and it works. But if i set time dilation to 0 the particles disappear, as if it was destroyed. Then when i set time dilation > 0 it starts over from start.
How about set it to 0.00000001? pretend it to be 0 
.i didn’t try It,this is a something I imagined.
Have you tried Set Paused on the Niagara Component in question?
Setting time dilation < .0001 makes the particle disappear.
Its a particle component, not a Niagara component. Does that matter?
Ok. I convert to the niagara system. Things are working. However, set pause does not seem to work. If i set pause to true at begin play it stops the particle from starting. Then unpausing it will let the particles form.
Set pause does not seem to do anything after the particles form.
I used a different niagara particle system and it pauses and restarts as it should. For some reason the original particle system will not psuse.
