Protect a Package file ?

Hi, no. I don’t know if it’s possible to implement this feature but it would technically be against the license agreement. We, creators, do not own the package, a game file, only 3d models and images. EA reserves all rights for the game files and does not allow preventing people from modifying or accessing them. You can say “do not edit and redistribute my 3d models/images” because you are their owner and can use them for other purposes, but you cannot prevent people from accessing, editing or redistributing the package.
What individuals do with their cc is their business(paywalls, for example, are also against the rules) but our developers cannot violate the rules (same goes for  adding a feature that removes pack requirement)
