The Witcher 4 is in production hell because of the Unreal Engine

Daniel Vavra, creator of the Kingdom Come trilogy and Warhorse Studio co-founder, criticizes Unreal Engine's limitations for complex open-world games, citing its struggles with vegetation rendering as a major drawback. He suggests this is a contributing factor to the reported difficulties in The Witcher 4's development.

"Unreal excels in environments like deserts and rocky landscapes, but struggled significantly with trees for a considerable period," Vavra claims, highlighting Nanite technology's apparent shortcomings in handling realistic vegetation. He references conversations with a CD Projekt employee, who allegedly confirmed that scenes easily rendered on RED Engine presented significant challenges in Unreal Engine, leading to substantial development hurdles.

Vavra points out the common practice of open-world developers utilizing proprietary engines, questioning CD Projekt's decision to switch to Unreal given their established RED Engine. While acknowledging Unreal Engine's visual capabilities, he notes the high-end hardware requirements, making the game inaccessible to many players.

Despite its age, Kingdom Come: Deliverance continues to captivate players. The highly anticipated sequel, launching February 4th, promises enhanced visuals, refined combat, and a historically-grounded narrative continuing Indřich's journey.
