In addition to the network changes to the engine used in Fallout 4, the Fallout 76 implementation of the engine was described at the game's E3 reveal as having 'all new rendering, lighting, and landscape technology'. A primary issue facing the developers was that components of the core engine (dating back to Gamebryo used in The Elder Scrolls III: Morrowind) such as quests or world loading were designed centering on a single player (dubbed ' Atlas' by the developers for its role in holding up the fabric of the loaded game world), a paradigm that would need to fundamentally change to allow multiple players spanning multiple worlds. This was considered a challenge by experts in the online game industry. In conjunction with idвЂ…Software (a fellow ZeniMax subsidiary), BattleCry attempted to integrate id's Quake netcode into Fallout 4's engine. Shortly before the release of Fallout 4, while Bethesda Game Studios began development of Starfield and downloadable content for Fallout 4, what is currently BethesdaвЂ…GameвЂ…StudiosвЂ…Austin (at the time BattleCry Studios) was tasked with modifying the Creation Engine to support multiplayer content in preparation for the development of FalloutвЂ…76.

Additionally the updated version of the Creation Engine powering Bethesda's FalloutвЂ…4 offers more advanced character generation. Bethesda worked with technology company Nvidia to implement volumetricвЂ…lighting through a technique that makes use of hardwareвЂ…tesselation. After using the Gamebryo engine to create TheвЂ…ElderвЂ…ScrollsвЂ…III:вЂ…Morrowind, TheвЂ…ElderвЂ…ScrollsвЂ…IV:вЂ…Oblivion, and FalloutвЂ…3, Bethesda decided that Gamebryo's capabilities were becoming too outdated and began work on the Creation Engine for their next game, TheвЂ…ElderвЂ…ScrollsвЂ…V:вЂ…Skyrim, by forking the codebase used for Fallout 3.ДЇollowing the completion of Skyrim, Bethesda set out to enhance the graphical core of the Creation Engine by first adding a physicallyвЂ…based deferred renderer to allow for more dynamic lighting and to paint materials object surfaces with realistic materials.
