Is there a way to invert a section of a projected field? I assume there isn't, but that seems like a big feature to be missing.
If you want to create a tunnel through a forcefield, it becomes a huge project that takes at least 5 projectors. It becomes troublesome, unreliable and clunky when it could be really simple if another block were added.
This could be fairly easily implemented by adding a projector upgrade that, creates a sort of invisible nega-forcefield that prevents forcefields from affecting the area.
Of course, this would have to only work on forcefields that are linked to the same core, lest someone could easily break in.
Anyway, I hope my suggestion will be taken into consideration, it would be greatly appreciated since now I have to come up with some way to make a tunnel through my shield.
