Question how does one get a marketplace bought item that uses a plugin to show up on source built engine?
Move plugin manually from Epic Games\4.XX\Engine\Plugins\Marketplace to your source engine plugins folder or your project/plugins folder.
But I do not have 4.24 version as binaries in my Epic Launcher, so I have to download 10 gb+ 4.24 version just so that I can download compatible plugins ?
You can configure installer options to download only minimum binary editor, itās around 4gb.
And today UE5 is 32gb. And you still have to install it in order to get some plugins from marketplaceā¦
