Editor Tick Component
Add this component to an Actor Blueprint and select its "On Editor Tick" event to receive events in editor preview windows
Works in both the BP viewport and in levels
Can be suppressed using CVar
rtm.Editor.AllowEditorTickComponent=false(global) or unchecking theAllow Editor Tickcheckbox (per instance)
