Laser Swamp:
To make a better effects of laser swamp, you'd better use the module in pairs. The modules should aim at each other in pairs, so that the player moving through the laser swamp will not block the light and there no “shade” side of the laser swamp. If you want to make a large area of laser swamp, you can also use two or more pairs of modules. And please note that, the modules have to aiming at each other at the same hight，and the lines from each modules must be overlapped at each other to make a single surface.
