Case Study: 51WORLD halves Unreal Engine build time (60→30 mins) with Incredibuild

Speeding up the earth’s VR clone with half the effort

51WORLD, a digital‑twin and VR specialist founded in 2015, was struggling with very long Unreal Engine 4 build times on Windows that slowed development and raised labor costs for its Earth Clone team. To tackle slow C++ and shader compilations during large‑scale development, 51WORLD selected Incredibuild as an accelerator for faster, distributed builds.

Incredibuild deployed a distributed build solution across about 20 machines (just over 200 CPU cores), cutting UE4 compile time from roughly 60 minutes to about 30 minutes — effectively doubling build speed. More than 30 developers now use Incredibuild, improving quality and time‑to‑market, and 51WORLD praised Incredibuild’s product design and China team support.
