Hi Keru,
In order to get a proper answer for this, I would need a couple of things clarified. Are you sharing this project with other UE4 developers rather than the public? If so, then you are fine to share all of your assets and code.
If you intend to share with people who are not already subject to the Unreal Engine 4 EULA, then that would not be allowed. Please let me know if that helps to clarify and if you have any other questions.
