Use Epics content in marketplace asset?

I plan releasing my first asset on the marketplace. Quick question:

Is it ok to use starter content or the mannequin+animation in my marketplace example map to show how my blueprints work?
I’m not sure about that.

I’m no expert on the Marketplace, but it should be fine. A lot of blueprints on the Marketplace use the default mannequin, such as this Interaction Blueprint: Character Interaction in Blueprints - UE Marketplace. Again I’m no expert, if you do need more clarification there should be a rules and regulations tab in the Marketplace.
