    	FVector tileMultiplier(tileSize, tileSize, 1);
    
    	if (InRoadSpline.Num() >= 2)

    		RoadSplineComp->SetWorldLocationAtSplinePoint(0, InRoadSpline[0] * tileMultiplier);
    		RoadSplineComp->SetWorldLocationAtSplinePoint(1, InRoadSpline[1] * tileMultiplier);
    
    		//set the remaining points if they exist
    		for (int32 i = 2; i < InRoadSpline.Num(); i++)
    		{
    			RoadSplineComp->AddSplineWorldPoint(InRoadSpline[i] * tileMultiplier);
    		}
