LI PASS PAK Build Tool (Unreal Editor)

LI PASS supports hot updates. By packaging resource files into a PAK, online issues can be quickly fixed seamlessly.

When building a PAK, encryption signatures are usually enabled, and the necessary keys are sensitive and generally not provided externally. Other configuration options in the project also affect PAK building. Therefore, LI PASS has introduced a dedicated Unreal Editor tool module in the plugin, allowing users to build hot-update resource packages independently in Unreal Editor after integrating the LI PASS plugin.After the PAK is built, deliver the output to the relevant LI PASS staff for configuration and validation.

Operating steps
