Fallout 4 Update 1.46 released on October 15, 2026, targeting crashes on PlayStation 4 and PlayStation 5 when certain Creations add NPCs or looping audio. Bethesda also fixed four Creation Kit problems affecting file conversion, archiving and uploaded content. This is a technical repair patch, not a new Fallout 4 quest or DLC.
If your game has been crashing after installing an NPC Creation, the FaceGen fix is the main reason to update. There’s also an important limitation involving looping WAV sounds, where the temporary fix prevents the crash but doesn’t fully restore repeated audio playback.
Fallout 4 Update 1.46 patch notes: All fixes
The October 15 patch lists two PlayStation crash fixes and four Creation Kit repairs. The following table separates the platform crashes from authoring problems so you can find the change relevant to your installation.
| Area | Issue addressed |
|---|---|
| PlayStation NPC Creations | Crash involving generated NPC FaceGen data fixed |
| PlayStation looping WAV audio | Temporary crash mitigation; audio may play once instead of repeating |
| Creation Kit PreCombine | Filtered PC-to-PlayStation NIF conversion no longer hangs during recombination |
| Creation Kit file discovery | Files missing from archiving searches or appearing in empty explorer windows fixed |
| Creation Kit Bink videos | Video files detected but missing from Extra Files corrected |
| Creation Kit archive packing | SSF file types can now be included in archives |
Fallout 4 Update 1.46 fixes NPC FaceGen crashes on PS4 and PS5
Creations that introduce extra non-player characters could cause a crash while the PlayStation game processed their generated facial data. Bethesda’s Fallout 4 Update 1.46 release fixes that specific FaceGen failure. If you installed an NPC-focused Creation and the game stopped working, check that your game has received the latest patch before removing content.
This doesn’t mean every third-party Creation is guaranteed to work. Fallout 4 has many mod and asset combinations, and the patch notes only name the particular FaceGen crash. If a different Creation still causes a failure, record which item you’re using and whether the problem occurs in a new or existing save.
Looping WAV audio: What the temporary fix means
The other PlayStation repair in Fallout 4 Update 1.46 concerns audio files added by Creations. Some looping WAV files could crash the game. Bethesda has introduced a workaround that allows the sound to play once without crashing rather than fully supporting its repeated playback.
That means the game should be more stable, but a looping sound created by a mod may not repeat as expected. Bethesda describes this as a temporary solution. The game can avoid the crash while still playing the looping sound incorrectly.
Creation Kit changes for mod authors
The Fallout 4 Update 1.46 PC Creation Kit fixes are aimed at people building and packaging Creations. A filtered PreCombine conversion involving PC-to-PlayStation NIF files could get stuck waiting for geometry recombination; this should now finish correctly.
The update also repairs intermittent file-discovery problems when building an archive, Bink video files that were detected but not added to Extra Files, and missing SSF support in the archive’s allowed-file list. These are workflow fixes for creators, not new in-game building objects or additional Creation storage.
What versions and platforms receive the patch?
Fallout 4 Update 1.46 is identified as the October 15 patch, with PlayStation 5 showing version 1.000.010 in current version listings. The major named in-game fixes affect PS4 and PS5, while Creation Kit changes are for the PC authoring tool. An Xbox crash isn’t among the two PlayStation-specific fixes listed here.
If you play with Creations, finish installing the current game update before checking whether a previously troublesome mod still crashes. Creation authors should update their authoring tools before rebuilding content affected by the four named packaging bugs.
Does Fallout 4 Update 1.46 add content?
No new missions, settlements, characters or Creation packs are listed in the October 15 Fallout 4 Update 1.46 notes. The changes address stability and the Creation Kit. The earlier 2026 Creation storage expansion and asset compatibility improvements were separate updates.
If Fallout 4 still crashes after installing the patch, note the platform, game version, affected Creation and whether looping audio or an added NPC is involved. Don’t delete a working save or library of Creations based solely on a patch intended to repair these specific failures.
