With Lumberyard 1.21, Amazon has released the latest beta version of its in-house free game engine. The release includes an automated animation system, an update to PhysX 4.1 and more. This version is also intended to simplify the development of games for multiple platforms.
Animation Editor and Physx system

The new features include the new “Simulated Objects” node in the Motion FX animation editor. It can automatically chain secondary animations to create dynamic dependencies. This makes it possible, for example, to simulate a character’s clothing or hair based on their movements. You can influence the simulation for each individual joint with the help of parameters such as Stiffness, Gravity or Collider.
In addition, the implementation of PhysX (Nvidia’s real-time physics system) was updated to PhysX 4.1.
More new features
- Script Canvas Visual Scirpting with new nodes: Repeter, Switch, Sequencer
- Launcher Projects were reduced from the previous nine to just two: Client and Server. This is intended to reduce platform-specific code and therefore simplify development. You can find out more here.
