Make a Realtime Color Difference Keying Material in Unreal Engine (by stealing from Composure)
This video shows how you can take the Color Difference keyer built for Unreal Engine's Composure toolset, and use it to build your own Real Time Color Difference keying material for Virutal Production. The resulting material can be instanced to easily key any greenscreen texture, including real time video feeds via USB, AJA/BlackMagic board, NDI, etc., as well as video or still image file sources.
