Amazon has announced the release of Lumberyard, its real-time engine originally based on CryEngine.
New features in version 1.14 include several new components such as a Wind Volume which can affect vegetation, particles and physical objects; a Sky Cloud component adds realistic cloud effects using either sprite-based or voxelised 3D volume shading; and a Force Volume that can be used to add physical force to objects that fall within a volume.
Read all the new features in the Lumberyard changelog, and find out more about the engine on its website.
