You need to use Mouse.UnitRay which originates from the camera and points towards the mouse’s world position. Then, using CFrame.fromMatrix(), you can make the camera face there:

local rs = game:GetService("RunService")
local mouse = game.Players.LocalPlayer:GetMouse()
local camera = workspace.CurrentCamera

local function cameraToMousePos(unitRay, position) --forlook vector

    local lookVector = unityRay.Direction --the direction of the ray
    local modelUpVector = Vector3.new(0, 1, 0) --unit vector, magnitude doesn't matter
    local rightVector = lookVector:Cross(modelUpVector) --cross to get a perpendicular rightVector
    local upVector = rightVector:Cross(lookVector) --same, but with upVecctor

    return CFrame.fromMatrix(position, rightVector, upVector) --we only need to provide two vectors and a position

end

rs.RenderStepped:Connect(function() --every frame

    camera.CFrame = cameraToMousePos(mouse.UnitRay, camera.CFrame.Position) --don't change the position, just orientation

end)

DM me if you want further explanation.

I hope that helps!

What do you mean? If you mean that you want to make player’s camera face toward to the point where your mouse is pointing, then you will need to use LocalScript ,:GetMouse() and CFrame.new(p1,p2).

Also you need Runservice to refresh your camera’s CFrame.

local Service = game:GetService("RunService")
local Player = game.Players.LocalPlayer
local Mouse = Player:GetMouse()
local Camera = game.Workspace.CurrentCamera
Service.RenderStepped:Connect(function()
	Camera.CFrame = CFrame.new(Camera.CFrame.Position,Mouse.Hit.Position)
end)
