Sample project for free plugin contains Epic's sample content?

Recently I released a free plugin for the Unreal community along with a sample project demonstrating how to use the plugin. The sample project contains a map I’ve made using the starter content and my own blueprint assets. However some visual props in the map are assets sourced from various Epic created sample content including the “Content Examples” project and also from other free sample projects put up by Epic on the “Engine Feature Samples” (from the “Learn” section in the Unreal Launcher)

Now, only the C++ source code of my plugin I released into Github under an MIT license.

My sample project and plugin binaries were offered as a separate zip download on a forum thread.

Is this alright?

At first I didn’t even think this was an issue as I haven’t explicitly sub-licensed any sample content (just provided my free project as a download which happens to contain some sample assets from Epic as visual props) but today I was worried while thinking about this and thought it best to get a direct confirmation from Epic.

Should I just add an explicit warning next to the download link that the sample project contains some content from Epic’s samples and users of the project will have to adhere to Epic’s EULA for content created by Epic? Or do I need to scrub all Epic assets other than starter content out of the project and reupload it?

Thank you for clarifying!
