Customize and use Epic content - EULA

I’d like to know what is the terms to customize Epic’s free contents.
After reading the EULA, I didn’t quite understand if we can freely(totally) modify the Examples(Assets).

c. Distribution and sublicensing of Examples - You may Distribute or sublicense Examples (including
as modified by you under the License) in Source Code or object code format to any third party.
However, the rights in this Section 1(c) do not expand or modify your limited Distribution and
sublicensing rights for Engine Code and Content (including as modified by you under the License)
that are not Examples.

This question came to my mind after my team decided to use First Person Gun for our first prototype, modifying material, Texture, Mapping, and thinking about even modifying the Mesh for it. We would use the template to create our own Weapon.

You’re fine to do as you propose, including whatever modifications you want.
