Activision has announced the release of open-source data for the Call of Duty: Warzone Caldera map, one of the largest in-game data sets ever released from the franchise. Players will now have the opportunity to utilize this data in their own projects.
The data set, available on GitHub, is referred to as Universal Scene Description (USD) which enables detailed 3D simulations of the Caldera map. This data, which includes the majority of the map’s geometry along with in-game character pathing, will be accessible in OpenUSD on Wednesday.
Described as “one of the largest publicly available OpenUSD data sets” by Activision’s senior VP of software engineering Michael Vance, the Caldera set is extensive in terms of world-size, scene graph depth, collisions, and more.
The Caldera map in-game is already sizable, making it a perfect choice for this project. It stands as one of the largest maps ever created in the franchise, competing with the original Warzone map and Call of Duty: Modern Warfare’s Verdansk. The data itself will be approximately 4GB in size.
Sharing this data will not only allow developers to use it for modding and AI training, but will also aid in future Call of Duty development. Being a mostly completed map that has already proven successful with the public, it serves as a valuable resource for such endeavors.
Michael Vance mentioned, “We feel a constant need to improve the play experience and deliver even more richness and detail. Innovations that come from this data set release could give more freedom and flexibility for our content teams to find the most engaging scenarios for our players.”
The Caldera map was initially introduced in 2021 as part of the Warzone Pacific update. It featured a massive battle royale map with 15 areas to explore, some of which were based on other multiplayer maps from the franchise. The Pacific update was later renamed to Warzone Caldera but was ultimately shut down in 2023 to make way for Warzone 2.0.
