LI PASS PAK Build Tool for Unreal Editor
LI PASS supports hot updates to quickly fix online problems discreetly, by inserting resource files into the PAK file directly.
When building PAK files, encryption and signing are usually enabled, but the keys being used are sensitive and not generally available. In addition, the other configuration items in the project may also affect PAK building. As such, a tool module has been added to the LI PASS plugin for Unreal Editor, for developers to easily build hot update resources with the Unreal Editor after the LI PASS plugin has been integrated. After which, provide the product to the LI PASS joint debugger for verification and configuration.
