Ah ha… After extracting the pak file, it only had the asset registry bin file and some other json file in it. No other asset content. So I’m guessing my test content in the plugin is being ignored because it is not being referenced anywhere in the project. I tried using “Additional Asset Directories to Cook” but that only lets you add sub folders of the main project’s Content folder. No plugin folders allowed. So I tried ticking “Cook everything in the project content directory” but that option then fails to produce a pak file at all, and by the name I’m guessing it only applies to the main project anyway. Do you know how to force content in the plugin to be cooked and added to the pak?
I’ll take a look at your updated repo as I’m guessing you got it to cook your TestActorExampleA from the plugin and I’m assuming your not directly referencing that asset in the main project? So you must have some setting set somewhere? I have no idea where to look though.
