Unreal marketplace licensing

Hi there,

I’m looking at starting a project and maybe developing it to sell. I would like some clarification about ethical and legal usage of content I would purchase on the Unreal market place. If I was to purchase a game template and develop something from there would I be allowed to sell copy’s of it? And if so would I need to give royalties to the person who developed the game template or would just purchasing it from the store cover this?
