The 4.23 update is now live!
This includes a significant optimization pass that opens up new “Fast” spawn variants. The TLDR is that these new “Fast” variants don’t spawn a new Feedback Event Factory actor; they just spawn the events associated with the factory and populate a struct handle (FActiveFactoryInfo) with information about the newly spawned events.
I did my best to ensure that there would be minimal work required to upgrade to this new version, but please note that this update may require some changes to your project. Specifically, info about active events (e.g. audio components, particle system components, etc.) now live in a FActiveFactoryInfo struct on the Feedback Event Factory rather than directly on the Feedback Event Factory actor itself.
