This session recorded at Unreal Fest Chicago 2026 provides an in-depth walkthrough of Unreal Build Accelerator (UBA), how it works with Horde—and how we use them together at Epic Games.
UBA distributes heavy compilation tasks across local or remote machines to speed up builds.
We go deeper on UBA, how we have it set up internally at Epic for our build farm, and how Horde and UBA provide access to a massive fleet of helpers for developers in office and working from home.
The talk also explores what’s new in UBA since Epic first talked about it at Unreal Fest Seattle in 2024.
