Epic is partnering with Unreal Engine Marketplace creators to offer select content to the UE4 community for free. This means developers using Unreal Engine will have access to more resources at no additional cost.
Epic has announced 18 new pieces of high quality content that will be free to download throughout the month of November, and once you download the content it's free for you to use in your projects.
