The Filter Toolkit is a set of blueprints which can be used to filter a signal. In the Filter Toolkit, all filters are designed as Actor Components. To start using them, you just need to add the desired filter as an Actor Component of the Actor whose behavior requires filtering.
Once it’s done, the parameters of the filter can be adjusted in the Details panel (when the component is selected).
Now, you’re ready to use the filter: just call the GetValue method of the filter, providing your signal as input, and get the filtered output.
More details about the different filters and the way they work is given here.
