When I open the package manager, I want to find package named ‘Cinemachine’. But there are only official, that I already have packages. Is that function of installing packages from package manager only for a pro version of Unity? Because I don’t see any packages.
Try selecting All packages within Package Manager
I have a problem, the option “All packages” is not there
Not sure if you can see pro packages but there is a settings button, go to advanced settings and check “enable preview packages something like that” then if you dont have all packages so you must have unity registry option, click there and search for it.
