Bohemia Interactive Simulations Uses Epic Games MegaGrant to Extend Mantle ETM Capabilities to Unreal

Apr 26, 2022

ORLANDO, Fla. (USA) — Bohemia Interactive Simulations (BISim), a global developer of advanced military simulation and training software, announces that it has integrated the Unreal Engine with its Mantle ETM platform, funded in part by a recent Epic MegaGrant.

Mantle Enterprise Terrain Management (ETM) is a custom-built platform based on proven COTS components and expert design/development services for creating simulated terrain for training, mission rehearsal, visualization, and terrain analysis. Mantle ETM streams procedurally enhanced content to runtime applications and support web applications, VBS Blue based products (e.g. VBS4 and VBS BlueIG), Cesium, and now also the Unreal Engine.

A new Unreal plugin was developed to stream terrain from Mantle ETM. The plugin provides WGS-84 (round Earth) support with real-world view distances and renders data layers from Mantle ETM including heightmap, albedo textures, and surface definitions. Importantly, Mantle ETM supports perfect correlation between runtimes, i.e. object placement and textures rendered in Unreal are identical to those rendered in VBS4, with exactly the same object placement down to the position of individual leaves and grass.

Correlated terrain data between runtime applications, for example, VBS4, Cesium, and Unreal, provides tremendous flexibility and directly supports integrated Live-Virtual-Constructive training events by assuring that all users are operating on identical terrain, regardless of the rendering engine they are using.

“BISim is passionate about its mission to harness the explosive potential of technology to revolutionize training and simulation”, says Pete Morrison, BISim’s Chief Commercial Officer and one of its founders. “Mantle ETM represents a step-change in capability for organizations to manage terrain data, and our work with Unreal adds another popular runtime engine to the Mantle ecosystem”.

This capability further advances the philosophy behind Mantle ETM, that organizations should leverage cloud technology to centrally store and manage terrain data and stream that data on-demand as needed - even to high fidelity 3D training applications built upon the latest game engines.
