First of all, thank you for the video tutorial of "Xiao Zhou's Dad", the Up master of station b.
The discovery is actually very simple,
First, in the niagara system, set a variable in the "user public" parameter, and pass this variable to the particle system.
The second is to set an actor in the blueprint, add a niagara component, and connect this component to the niagara system.This parameter is naturally exposed in the blueprint.Then set the keyvalue value of niagara in the blueprint.

It's a bit confusing to say that.As shown below.
Below is the blueprint file and niagara particle system file, myRate is the variable

Look inside the blueprint

look againLooking at the particle system

it is clear that this variable myRate is an examplegeneration rate.Of course, not only floating point types can be passed.Click the "+" to the right of "User Exposure", and find that variables of various data types can be passed.

Look at the effect, when myRate = 100,

myRate = 10000,
