why doesnt the camera focus on the position given?

local replicated = game:GetService("ReplicatedStorage")
local Players = game:GetService("Players")
local StarterGui = game:GetService("StarterGui")
local ReplicatedFirst = game:GetService("ReplicatedFirst")

local ImpParts = workspace:WaitForChild("ImportantParts")

local ClientEvents = replicated:WaitForChild("ClientEvents")
local Gui = replicated:WaitForChild("Gui")
local ServerEvents = replicated:WaitForChild("ServerEvents")
local Values = replicated:WaitForChild("Values")

wait()

local Cam = workspace.CurrentCamera
Cam.CameraType = Enum.CameraType.Scriptable


local D1 = ImpParts:WaitForChild("CameraD1")
local D2 = ImpParts:WaitForChild("CameraD2")
local D3 = ImpParts:WaitForChild("CameraD3")
local D4 = ImpParts:WaitForChild("CameraD4")
local Spawn = ImpParts:WaitForChild("Spawn1")

Cam.CoordinateFrame = CFrame.new(D1.Position) 
Cam.Focus = CFrame.new(Spawn.Position)

this wont return any errors and its in a local script(fe is on)

I think you didn't set the camera's focus correctly, and there may be another errors.

Try this:

local replicated = game:GetService("ReplicatedStorage")
local Players = game:GetService("Players")
local StarterGui = game:GetService("StarterGui")
local ReplicatedFirst = game:GetService("ReplicatedFirst")

local ImpParts = workspace:WaitForChild("ImportantParts")

local ClientEvents = replicated:WaitForChild("ClientEvents")
local Gui = replicated:WaitForChild("Gui")
local ServerEvents = replicated:WaitForChild("ServerEvents")
local Values = replicated:WaitForChild("Values")

--Add camera variable here
local camera = workspace.CurrentCamera
local camera.CameraType = Enum.CameraType.Scriptable


wait()

local D1 = ImpParts:WaitForChild("CameraD1")
local D2 = ImpParts:WaitForChild("CameraD2")
local D3 = ImpParts:WaitForChild("CameraD3")
local D4 = ImpParts:WaitForChild("CameraD4")
local Spawn = ImpParts:WaitForChild("Spawn1")

camera.Focus = CFrame.new(Spawn.Position)
--if this won't work, make the last line be: "camera.Focus = Spawn"

If this works, mark as the solution, and as always, good scripting! ;D
