XFSDK Family
Explicit rendering. Modular control.
XFSDK is a family of rendering and runtime tools for Unreal Engine 5. It provides alternatives to workflows that depend heavily on temporal reconstruction, along with production tools such as loading screens, PSO prewarming, and texture processing.
The goal is additional opt-in choices with documented integration requirements, visual trade-offs, and measurable costs—not an automatic replacement for every default Unreal Engine rendering feature.
Choose a product
| Product | Role | Engine dependency | Documentation |
|---|---|---|---|
| XFSDK Core | Advanced framework with shared GI/runtime systems and further rendering features (TBD) | Unreal Engine X required | Getting Started and demo |
| XFSDK Light | Fab-oriented rendering and startup toolkit | Standard supported UE5 configuration | Getting Started |
| XFSDK Enhanced SMAA | Standalone SMAA from Light | Check standalone product requirements | Overview |
| XFSDK Hybrid SDF GI | Standalone GI offering using the shared GI technology | Check standalone product requirements | Standalone product overview |
| XFSDK Texture Works | Texture conversion, baking, and packing | Standard Unreal Editor workflow | Documentation |
How the products relate
- Core contains Hybrid SDF GI, loading screens, and PSO prewarming, with the underlying implementations also used by Light. Core requires Unreal Engine X.
- Light provides those systems for supported stock Unreal Engine projects, alongside separate SMAA and Bend-style screen-space shadows implementations.
- XFSDK Enhanced SMAA provides Light's anti-aliasing separately.
- XFSDK Hybrid SDF GI is the standalone GI product; its technical reference describes the shared implementation, not a standalone installation guide.
- XFSDK Texture Works is an editor-side asset workflow tool rather than a runtime rendering replacement.
Design principles
- Explicit choices: rendering methods and startup features are deliberately enabled.
- Native-resolution image quality: preserve spatial detail without promising artifact-free results in all scenes.
- Modular adoption: use only the products needed without requiring the advanced engine fork unless specified.
- Production integration: document quality settings, API access, requirements, and limitations.
- Measured trade-offs: compare GPU cost and visual quality under repeatable conditions.
