We are currently in the midst of creating a game with our own assets, although some of the unreal assets which are pre-made such as the cliff scenery would save a substantial amount of time.
Is it possible to use the Unreal Engine Assets in a game we plan on selling?
This is correct. Any assets that you purchase from the marketplace or are given for free are all items that you can use in a final product. Please let us know if you have any questions.
