The 3D engine Lumberyard from Amazon is now open source. In DP 06 : 2018 , our author Alexandra Kaschny commented on Lumberyard as part of our engine safari : “It will probably be in beta for all eternity, but with Amazon it has a big name behind it – maybe it will make it to the actual release at some point.
