How to make GUIs visible for all players?

Title kind of explains it all, i tried with a remote event and had no success. I also tried the basic way.

2 ways to go around it

  1. like you said; give some sort of signal to all players (such as a remote event or an attribute)
  2. just setting it to being enabled (altough first option is better immo)

It depends on what you want to achieve
Is this a shop ui in between rounds? Use attributes/other way’s to tell the client the state of the game

SO; what is your goal?

Its a way of masking teleporting the players’ characters.
So kind of a transition screen if you know what i mean. It needs to pop up and mask the screen just before the teleporting and getting disabled after players are tp’d.

Teleport in place, right?

Tell the client’s via remote event where they should teleport themself
do the transition, teleport, fade out

Use a remote event for this

Not places, Im just changing the players’ primaryPart’s CFrames

Yeah; so what i have said *****

Got it, thanks ******** (50 chars)

How can i get the GUI? I’ve tried over and over again with different ways and it doesnt work at all.
