How to make overlay that is visible to only 1 player?

when you said this

did you mean an overlay or a button button

a green button, for the teleporting to the cameras

ok so then

green Button pressed → trigger relay

Relayed → show overlay

green Button pressed (the one that takes you out) → hide overlay

Does this help?

a lot. thanks!
but now there are the door overlays. do I just do the same?

yes i think

worked for the cameras, but not sure bout the doors, because there are multiple overlays that place in the same spot as their counterpart.
like [Close Right Door] will disappear and [Open Right Door] will appear, replacing it.
i’ll figure it out later
