The latest beta version of Apple’s Reality Composer Pro 3, the content creation tool used to create spatial experiences for Apple Vision Pro, appears to contain traces of “The Machinery,” an ambitious game development project that abruptly shut down in 2022 without explanation.
Based on code discovered by Nicolás Alvarez and independently confirmed by WoozadThe binaries included with Reality Composer Pro 3 beta contain at least 40 mentions of “the machinery” or “our machinery” and correspond to aspects of The Machinery’s project structure, asset management system, and database architecture.
The results are notable because The Machinery was developed by Our Machinery, a company made up of veterans of the Bitsquid game engine. The project has gained a devoted following among engine programmers for its unconventional approach to content creation workflows. And yet, he disappeared without a trace.
At the heart of the project was a system known as “The Truth”, a database-driven architecture designed to unify publisher assets, objects, dependencies, and state. Many of the same concepts appear in the latest version of Apple Reality Composer Pro, announced at WWDC 2026. Things like reusable prototypes, live editing, asset dependency tracking, and rapid iteration workflows all appear – ideas that have notable technological similarities to how The Machinery works. Direct references in the code appear to confirm the connection.
Links don’t just extend to strings of code. Tricia Gray, co-founder and CEO of Our Machinery, now works on Apple’s spatial computing development tools team, as evidenced by her LinkedIn profile.
It’s unclear whether Apple licensed The Machinery or acquired the company, or somehow inherited the referenced technology, but the presence of the identifiers in Apple’s code suggests that at least some of the project’s ideas found their way into Apple’s spatial computing development toolset.
The discovery is particularly notable because development of The Machinery ended so suddenly, surprising many developers at the time who had been following the project’s progress. We have contacted Apple for comment on the findings and will update this story if we receive a response.
