B1AnimNotifyState_PlayVATAnim

File: BlueClient2/Source/BlueClient/Animation/AnimNotifies/B1AnimNotifyState_PlayVATAnim.h / .cpp Base Class: UAnimNotifyState

Purpose

Plays a Vertex Animation Texture (VAT) animation on a spawned Static Mesh Actor for the duration of the notify range. VAT is used for lightweight prop animations that don't require a Skeletal Mesh (e.g., a folding chair, a flag waving).

How to Add in the Editor

1. Open an Animation Montage or Animation Sequence.
2. Right-click on the Notify track → Add Notify State → B1AnimNotifyState_PlayVATAnim.
3. Assign the StaticMesh (must have a VAT material) and set AnimName in the Details panel.

Editor Properties

Property	Type	Default	Description
SocketName	FName	—	Socket at which to spawn the mesh
StaticMesh	UStaticMesh*	—	Static mesh with a VAT-compatible material
bAttached	bool	false	If true, the spawned mesh follows the socket during the animation
bSync	bool	false	If true, synchronizes the VAT start time with the current montage playback position
LocationOffset	FVector	(0,0,0)	Position offset
RotationOffset	FRotator	(0,0,0)	Rotation offset
Scale	FVector	(1,1,1)	Scale of the spawned mesh
AnimName	FName	—	Name of the VAT animation sequence to play

Behavior

Callback	Action
NotifyBegin	Spawns AStaticMeshActor with UB1AnimToTexComponent; if bSync, calculates the VAT start time from the current montage position; calls animToTexComponent->PlayAnimSequence(AnimName, startTime)
NotifyEnd	Destroys all spawned actors for this notify instance and cleans up the internal tracking map
