NetPriority변수 또는 GetNetPriority 함수를 오버라이드해 구현하면 됩니다.
액터의 기본 우선권 값은 1이며, 최종 설정 값 산출 로직은 다음과 같습니다.

float AActor::GetNetPriority(const FVector& ViewPos, const FVector& ViewDir, AActor* Viewer, AActor* ViewTarget, UActorChannel* InChannel, float Time, bool bLowBandwidth)
{
	if (bNetUseOwnerRelevancy && Owner)
	{
		// If we should use our owner's priority, pass it through
		return Owner->GetNetPriority(ViewPos, ViewDir, Viewer, ViewTarget, InChannel, Time, bLowBandwidth);
	}

	if (ViewTarget && (this == ViewTarget || GetInstigator() == ViewTarget))
	{
		// If we're the view target or owned by the view target, use a high priority
		Time *= 4.f;
	}
	else if (!IsHidden() && GetRootComponent() != NULL)
	{
		// If this actor has a location, adjust priority based on location
		FVector Dir = GetActorLocation() - ViewPos;
		float DistSq = Dir.SizeSquared();

		// Adjust priority based on distance and whether actor is in front of viewer
		if ((ViewDir | Dir) < 0.f)
		{
			if (DistSq > NEARSIGHTTHRESHOLDSQUARED)
			{
				Time *= 0.2f;
			}
			else if (DistSq > CLOSEPROXIMITYSQUARED)
			{
				Time *= 0.4f;
			}
		}
		else if ((DistSq < FARSIGHTTHRESHOLDSQUARED) && (FMath::Square(ViewDir | Dir) > 0.5f * DistSq))
		{
			// Compute the amount of distance along the ViewDir vector. Dir is not normalized
			// Increase priority if we're being looked directly at
			Time *= 2.f;
		}
		else if (DistSq > MEDSIGHTTHRESHOLDSQUARED)
		{
			Time *= 0.4f;
		}
	}

	return NetPriority * Time;
}
