unreal engine | Simple Railing instace Blueprint

A simple Railing BP i did for NSR. But as I was busy puishing out assets and guiding the fresh gradution, I only set up the minumul requiment for the Blueprint. So it only spawn in one direction. But hopefully when I m free can polish it more.
The new one I did with my student is more advance as we change to using Spline. Hopefully can show that soon enought too.
