Is this meant to be like that? If you look at "Electrode generator - demo", the E-Wall vanishes and the clone produces a layer of electrode, but it does not accept the current to build an arc.
Well. My idea was, that the left trigger should open the E-Wall and power the Electrode at once. But apparently conductive particles do not lead current when placed 'in' a wall (even if it is an open E-Wall).
