Media.Monks gave multiple live demonstrations of the use of Unreal Engine for virtual production during the Open House.
Unreal Engine 5.5 was released back in November providing notable improvements in rendering, the animator rig, mobile game development and VR scouting, and the introduction of MegaLights in Lumen.
"Lumen in the Land of Nanite" is a tech demo, built with Unreal Engine V, designed to show off the Nanite and Lumen next-generation technologies.
