Overlay reference The overlay component and the overlay Anim Blueprints (pose, body, first person, layer blending).
How to read these tables
Settings are the values you tune: select the component in your pawn Blueprint (or open the asset) and look in the Details panel under the category shown. Runtime state is written by the system while it runs; read it, do not set it. Functions marked pure have no execution pins. The descriptions are the same as the Details panel tooltips. Default is the class default; where a sample pawn sets a different value on its component, the description says so (

Functions Function Inputs Outputs Description UpdateOverlayBody Links the anim layer class that matches the current OverlayBody onto the parent mesh. UpdateOverlayPose Links the anim layer class that matches the current OverlayPose onto the parent mesh. InitializeSystemParentMesh (SkeletalMeshComponent ref) Stores the parent mesh and links the initial overlay body and pose anim layers. Called once by the owner on setup. CloseOverlayMenus Closes the overlay pose and body menus without selecting anything: removes the switcher widgets and restores global time dilation to 1. Called from EndPlay, so a pawn destroyed with a menu open does not leave the game slowed down.
