Developer Notes

The plugin may not be loading soon enough. The Type should be "Runtime", and LoadingPhase should be PreDefault. As this plugin is a runtime plugin, and it's needed before the game modules, hence PreDefault.


If a project is packaged with a plugin that contains a custom struct and a function that takes that struct as a parameter, the game will crash when the executable is run.
