```auto
if(bWeaponEquipped && EquippedWeapon && EquippedWeapon->GetWeaponMesh() && PlayerCharacter->GetMesh())
	{
		LeftHandTransform = EquippedWeapon->GetWeaponMesh()
			->GetSocketTransform(FName("LeftHandSocket"), RTS_World);
		FVector OutPosition;
		FRotator OutRotation;
		PlayerCharacter->GetMesh()->TransformToBoneSpace(FName("右手首"), LeftHandTransform.GetLocation(), FRotator::ZeroRotator, OutPosition, OutRotation);

		UE_LOG(LogTemp, Log, TEXT("OutPosition: X = %f, Y = %f, Z = %f"), OutPosition.X, OutPosition.Y, OutPosition.Z);
		UE_LOG(LogTemp, Log, TEXT("OutRotation: Pitch = %f, Yaw = %f, Roll = %f"), OutRotation.Pitch, OutRotation.Yaw, OutRotation.Roll);
		LeftHandTransform.SetLocation(OutPosition);
		LeftHandTransform.SetRotation(FQuat(OutRotation));
	}

```

我是一个新手，在尝试使用FABRIK，将左手固定在枪械某部位。这里的`TransformToBoneSpace`接受一个Bone Name，我发现他调用了`GetBoneIndex`获取Index，填入我使用骨骼的BoneName，获取到了-1，即INDEX\_NONE，我该怎么处理，解决这个问题。
