Documentation Overview
Explore rendering, runtime, and asset tools for Unreal Engine 5.
XFSDK Family
XFSDK provides modular rendering and runtime systems for developers seeking control over image quality, feature selection, and startup workflows.
Includes XFSDK Core, XFSDK Light, XFSDK Enhanced SMAA, XFSDK Hybrid SDF GI, and XFSDK Texture Works. The GI technical reference covers the shared implementation.
Unreal Engine X
A focused Unreal Engine 5 fork for a narrower desktop rendering configuration and deeper engine-level changes. XFSDK Core requires Unreal Engine X; Fab plugins are a separate adoption path.
