Hmmm, after I added the “AdvancedSessions” folder in the Plugins folder, I generated visual studio project and I rebuilt the solution, maybe I need to build the plugin somehow separately?
EDIT: It says “MainFrameActions: Packaging (Windows (64-bit)): UnrealBuildTool: c1xx: fatal error C1083: Cannot open source file: ‘L:\Unreal Projects\TestScene 4.11\Plugins\AdvancedSessions\Intermediate\Build\Win64\UE4\Development\AdvancedSessions\Module.AdvancedSessions.cpp’: No such file or directory”
