Amazon ships Lumberyard 1.26

Thursday, October 8, 2020 | Written by Jim Thacker

Amazon has released Lumberyard 1.26, the latest beta of the game engine and development environment, and officially replaced the old CryPhysics system with the newer Nvidia PhysX system.

The version also adds support for dynamic slices in the terrain system, improves the workflow for manipulating objects in the viewport, and updates the new White Box Tool and UI 2.0 interface design.

CryPhysics has now been officially replaced by Nvidia's PhysX
The main change in Lumberyard 1.26 is that the old CryPhysics system – a holdover from the original developer Crytek – has been officially replaced by the PhysX Gem, which is based on Nvidia's real-time physics system.

All functions of CryPhysics have now been superseded by those of PhysX, with the exception of the CryVehicles system, which will be completely removed if CryPhysics is no longer supported in a future version.

The PhysX gem itself gets three new joint restrictions for fixed joints, ball joints, and hinge joints.

In related news, the PhysX Force Regions system allows wind settings to be shared between Lumberyard fabric simulations and particle systems, as well as other environmental influences.

Improved terrain and vegetation systems
The dynamic vegetation system introduced in Lumberyard 1.19 now supports dynamic slices so that users can create instances that contain multiple types of terrain, such as B. Rocks and sand to speed up the layout of the levels.

Plus, Lumberyard's old site code has now been condensed into a LegacyTerrain gem, so studios that don't use the legacy system can fully compile it.

The update also includes a PhysX-based Collider Surface Tag Emitter for distributing vegetation on surfaces.

According to Amazon, it offers a more efficient alternative to the old Mesh Surface Tag Emitter when working with more complex surfaces like rock walls.

Other changes: better interactions with viewports, updates to the user interface 2.0 and the white box tool
The interaction model for the Lumberyard viewport has also been updated, adding parent and local grids to make it easier to position assets. The camera controls now also comply with industry standards.

UI 2.0, the new interface design introduced in Lumberyard 1.25, is being developed further. Changes include new icon designs, increased use of windows with dockable tabs, and light and dark themes for the script console.

The other major change in Lumberyard 1.25, the new white box tool for level design testing, is now officially no longer an experimental feature, although since it is still in preview it is not ready for productive use.

Availability and system requirements
Lumberyard 1.26 is available now. The editor runs on Windows 7 and higher.

The engine is free to use for offline and local multiplayer game development, including source code access. Online games must use Amazon Web Services, which are billed at Amazon's standard AWS rates.
