GRILL® DIS is a plugin developed for both Unity and Unreal Engine that supports military-standard Distributed Interactive Simulation (DIS) data interchange. Developed with a focus on ease of use while also having an extensible architecture, the backbone of the plugin uses the free and open-source military maintained Open-DIS libraries. Example projects exist for both Unity and Unreal Engine that show various use cases of the GRILL® DIS plugin. The plugins and example projects are free, open source, and publicly available on GitHub and the marketplaces of Unity and Unreal Engine!
