How do I tween from a Scriptable camera to a Custom camera?

In my game, a player can press a button to activate a top-down view of the map. They can press the button again to recover their Custom camera.

The problem I’m having is that the camera goes into a first-person view for a split second, and then the camera fixes itself after I change the CameraType to Custom. I want the camera to smoothly fix itself; not abruptly.

Here’s what’s happening:

Here’s my code:

local TOP_DOWN_OFFSET = Vector3.new(-1, 90, 0);

local function ToggleCamera(actionName, inputState)
	if CameraMode == "TD" then
		-- Classic
		RunService:UnbindFromRenderStep("TopDownCamera");
			
		Camera.CameraSubject = Player.Character.Humanoid;
		Camera.CameraType = Enum.CameraType.Custom;
		local Tween = TweenService:Create(Camera, TweenInfo.new(0.4), {CFrame = Player.Character.Head.CFrame});
		Tween:Play();
	else
		-- Top-down
		Camera.CameraType = Enum.CameraType.Scriptable;
	
		local CurrentTopDown = Vector3.new(-1, 0, 0);
		local function UpdateCamera()
			if CurrentTopDown ~= TOP_DOWN_OFFSET then
				CurrentTopDown = Vector3.new(-1, CurrentTopDown.Y + 5, 0);
				RunService.Heartbeat:Wait();
			end;
		
			if Player.Character then
				local PlayerPosition = Player.Character.HumanoidRootPart.Position;
				local CameraPosition = PlayerPosition + CurrentTopDown;
					
				-- Follow the player
				Camera.CoordinateFrame = CFrame.new(CameraPosition, PlayerPosition);
			end;
		end;
		
		RunService:BindToRenderStep("TopDownCamera", Enum.RenderPriority.Camera.Value, UpdateCamera);
		CameraMode = "TD";
	end;
end;

ContextActionService:BindAction("ToggleCamera", ToggleCamera, false, Enum.KeyCode.C);

What am I doing wrong?

the issue is that you’re making the CameraType custom, and it overrides the tween. You should:

Do tween --> wait(0.4) --> make CameraType Custom
