UAnimInstance::NativePostEvaluateAnimation

function Engine Since 4.15

#include "Animation/AnimInstance.h"

Access: protected Specifiers: virtualENGINE_API

Description

Called after the anim graph has been evaluated and final bone transforms are computed. Override this to apply post-processing adjustments to bone transforms or read back evaluated results before they are applied to the skeletal mesh.

Caveats & Gotchas

• Bone transforms at this point reflect the anim graph output but have not yet been committed to the render thread. Modifications here affect the final pose that frame.
• This runs after parallel evaluation completes. Do not assume it is called on a worker thread — it executes on the game thread.

Signature

virtual void NativePostEvaluateAnimation()

Return Type

void

Example

Post-process head tracking after evaluation C++

void UMyAnimInstance::NativePostEvaluateAnimation()
{
	Super::NativePostEvaluateAnimation();
	// Adjust a bone transform after the graph has evaluated
	FTransform& HeadTransform = GetSkelMeshComponent()->GetEditableComponentSpaceTransforms()[HeadBoneIndex];
	HeadTransform.SetRotation(HeadTransform.GetRotation() * LookAtAdjustment);
}
