I was looking into example plugin templates from:
Editor > Setttings > Plugins> Add+ > Third Party Library
This sample plugin simply doesn’t get added on the MacOS version, but I can get it to work on Windows/Linux.
On MacOS version, creating this plugin I see the messagebox:
“Failed to compile plugin source code. See output log for more information.”
And output logs show:
LogWorldSubsystemInput: UEnhancedInputDeveloperSettings::bEnableWorldSubsystem is false, the world subsystem will not be created!
