Pak Loader Plugin 4.25
Exposes .pak file loading functions to Blueprints and provides functions to use assets from the pak file. Intended to be used in packaged (shipping) builds.
Pak Loader is a plugin that can be used in Blueprints and C++. Due to how Unreal Engine works, .pak files are only intended to be loaded in packaged (shipping) builds.
Accessing the assets within the Pak file depends on how the .pak was created (paths, mount points, etc.) and what you are intending to use it for.
You can find an example project and an example .pak file in the link below.
Read the documentation to learn about mounting pak files. If you are a new to Unreal this plugin might not be suitable for you, as mounting pak files is a non trivial thing.
