The Crown Jewels: Features Unique to the 4.26 Exclusives
When we talk about the exclusive nature of the 4.26 documentation, we are referring to three proprietary systems that hit their peak maturity in this build.
nDisplay Enhancements: Improved setup for multi-display rendering (LED volumes). Documentation highlights the nDisplay Config Editor, which simplified the mapping of 3D scenes across complex screen arrays. [1] 3. Animation and Physics
Example quick checklist for upgrading a project to 4.26
- Backup project and source-control commit.
- Read 4.26 release notes and known issues.
- Test in a copy: open project, run full lighting/build.
- Verify physics: enable Chaos only after validating major gameplay physics.
- Test Niagara systems on target hardware; add fallbacks or LODs.
- Run packaging for each target platform; resolve shader or plugin issues.
- Use profiling tools to locate new performance hotspots.
- Update any custom C++ APIs per 4.26 doc changes.
- Run automated tests and play through key gameplay scenarios.
