Bethesda Game Studios released Fallout 4 update 1.46 (version 1.000.010 on PlayStation 5) on October 15, 2026. This update primarily targets the Creation Kit and modding pipeline, resolving several issues that impacted asset conversion and archive management.
Creation Kit and Modding Improvements
The core of this patch addresses technical hurdles in the modding workflow. A primary fix targets the conversion of .nif files from PC to PlayStation when utilizing filtered PreCombines generated within the Creation Kit.
This update resolves a bug that caused an infinite loading screen during geometry recombination and archive updates. Additionally, the update restores reliable file discovery for archiving within the Creation Kit, ensuring necessary assets are identified during the packaging process.
Other Creation Kit enhancements include:
- Bink Video Handling: Bink video files (.bik and .bk2) are now correctly detected and added to “Extra Files” when identified by the system.
- Archive Inclusion: .ssf files are now included in the allowed file list for archive creation.
General Stability and Performance
Beyond the developer-focused changes, update 1.46 includes general stability fixes across platforms. These fixes are intended to improve the overall reliability of the game client during standard play.
