How would you make a billboard GUI appear and disappear depending on how far a player is from a block? Example, if the player is withing 5 studs of the block they can see it but once they leave those 5 studs it is not visible.
If you select the BillboardGui you will find the "Max Distance" option you can set that to what you want to make the GUI appear/disappear depending on how close the player is to the GUI
