Problem with UE4 cascade's trail source

Hi, I have been working with cascade’s trail source and stuck with a problem.
the trail is supposed to be created on every source particle, but I found that it is not.
It is quite hard to find information about it…

+also, is there any way to make deactivation of the ribbon smooth? for now, when source dies, trail disappear very sitff.


In Ribbon Data module you need increase Max Trail Count.

About smoothness - I still don’t have a universal solution. I usually try to smooth this out by animating the fade parameters through the trail’s material.

Yes! Max Trail Count seems to solve the problem.

Can you tell me some more about the fade parameter? Is it with dynamic parameter?

Yes, usually it is dynamic parameters. For example, turn off trails from blueprint when needed.
But the case is not universal.
