Very cool visuals! The only thing bothering me are the edges where glowing pipes connect to buildings, pumps, tanks etc. The mod treats them as a part of pipe series so the graphics cut abruptly. Will it be possible to add a special "edge case" either ignoring the connection if it leads to a non-pipe entity (and drawing a smooth glowing sprite variant on the pipe instead) or adding another special small sprite on the other end of the connection on top of the building? Or is it asking too much work or performance cost?
