In January 2019, following a dispute between Improbable and Unity Technologies over changes to the acceptable uses of the Unity game engine, Epic announced it was partnering with Improbable to launch a US$25 million fund to help bring developers they believe affected by these changes towards solutions that are more open and would have fewer service compatibilities.[65] Epic launched a US$100 million prize pool in February 2019 for Fortnite-related esports activities that it plans to run from 2019 onward.[66] To expand its esports initiatives, Epic Games hired Nate Nanzer from Blizzard Entertainment and their commissioner of the Overwatch League in May 2019.[67] At the 2019 Game Developers Conference, Epic announced it was launching a US$100 million MegaGrants initiative, allowing anyone to apply for up to US$500,000 in funding to support game development using the Unreal Engine or for any project, even if not directly games-related, that would benefit the Unreal Engine.[68] One of the first major funded entities under this was the Blender Foundation in July 2019, having received US$1.2 million from the MegaGrants funding, to help them to improve and professionalize their Blender tools for 3D art creation.[69]
