I had a sign to corral people into one way until the point was capped, at which point the brush it was on would break and it would stop blocking the way. However I noticed that the arrow overlay wasn't appearing, which is probably why a lot of people were confused So how would I have the wall have an overlay? Because i'm seriously contemplating making an actual, 3d arrow out of func_breakables to guide people. Are there other methods of creating a barrier that would disappear, and also have a arrow on it? And is it possible to have overlays disappear using inputs/outputs?
