Lets say that I did not pass perception check on someone that is in stealth mode in same room with me. Now, if I have NPC, or droid, or even another player with whom I share sensors in same room and they spot person in stealth mode, will I see it too?
Currently you will not. We may expand this in the future, but for now it is only player-vs-player checks for visibility.
"On two occasions I have been asked,—"Pray, Mr. Babbage, if you put into the machine wrong figures, will the right answers come out?" I am not able rightly to apprehend the kind of confusion of ideas that could provoke such a question."
