Amazon continues its effort to raise the profile and viability of its proprietary Lumberyard game engine by providing all developers using the platform a free perpetual license to the Lumberyard version of the newly-launched SpeedTree 8 animation tool.

Created by IDV, SpeedTree is a procedural 3D modeling technology that is designed to help developers model complex vegetation. The company claims that SpeedTree has been used in more than a thousand games and in more than 100 feature films and animations. The technology has received multiple awards, including the 2015 Scientific and Technical Academy Award and a 2015 Engineering Emmy.

As the latest incarnation, SpeedTree 8 includes new tools, powerful optimization techniques, refined geometry, and a fully-PBR workflow, as well as the debut of a new model library. Each new SpeedTree 8 model offers multiple resolutions, age variations, and infinite seasonal variations with a new season slider. The technology includes a software development kit that can be programmed to support any level of engine integration.

“SpeedTree 8 for Lumberyard is designed to be an intuitive and powerful toolset for both new and experienced game devs who want AAA quality vegetation in their Lumberyard projects,” said Michael Sechrest, co-founder of IDV. “Taking advantage of Lumberyard’s advanced rendering and lighting systems, teams can create large-scale environmental art faster and with greater fidelity.”

Beside being integrated with Amazon’s game engine from the get-go, SpeedTree 8 for Lumberyard is supposed to allow developers access to new techniques for low-poly branch structure modeling and mesh editing. Other features include automatic vertex color painting with in-modeler preview, one-draw-call models with tiling textures, wind, and LOD, and new art director tools.

“With Lumberyard, we’re giving developers everything they need to bring their most ambitious visions to life,” said Eric Schenk, General Manager, Amazon Lumberyard. “By seamlessly integrating with Lumberyard, SpeedTree 8 makes it easier to model, import, and customize visually-stunning vegetation in your games.”
