Is there a way to set a spawn point?

You can't directly set a player's spawn location. By default, the player will spawn at a randomly chosen SpawnLocation as long as it matches his TeamColor.

If you want to move the character as soon as he spawns, you can connect to the CharacterAdded event and teleport the player to a position.

function onPlayerAdded(player)
   player.CharacterAdded:connect(function(character)
      wait()
      character:WaitForChild("Torso")
      character:MoveTo(Vector3.new(0, 1000, 0))
      print("Teleported to position")
   end)
end

game.Players.PlayerAdded:connect(onPlayerAdded)

for _,player in pairs(game.Players:GetPlayers()) do
   onPlayerAdded(player)
end

My best advice is to make a spawn point with transparency infinitely.

Go to properities and change it to 1 or higher for more transparency.
