think (just about) all space games with ships that have shields, the shields are not directly on the hull itself but usually raised a bit above it. my idea is a "Shield block" a block that allows you to change what the shield goes over. it would only be visible in build mode, and anything connected to the shi would be able to shoot through it, like a turret. It would be a great way to preserve turrets and make the shield effect look better, kinda like in movies and Halo. basically it is an invisible block that can be shot through by your ship and connected things like turrets.
