OpenMW FNV world state - Windows Flat + VR (2026-07-23)

FNV coverage in this build

This combines the native FNV Save330 load path with the merged world-state slices through PR #12:

• exact native save master-order preflight
• faction reactions
• loaded world-reference transforms and facing
• loaded actor enabled/disabled state
• loaded ordinary-object enabled/disabled state

Release workflow: https://github.com/nikamigaming-create/nikami-openmw-lab/actions/runs/30007062397

Experimental boundary

This is not full retail Fallout: New Vegas parity. Known required work includes unloaded-reference persistence, non-player life/package/inventory state, remaining player actor-value/perk/reputation/crime state, quest/dialogue/effect scripts, broad object-script command semantics, dynamic forms, complete combat/VATS parity, and additional animation/body-language behavior.

Use legally owned game data. The companion BWorlds README provides the exact Flat, VR, menu, and native-save launch commands and constructs a save-ordered isolated content profile.

OpenMW FNV runtime fix — Windows Flat + VR

Windows prerelease for the native Fallout: New Vegas runtime work.

Assets:

• OpenMW-Flat-0.50.0-win64.exe — standard desktop build
• OpenMW-VR-0.50.0-win64.exe — OpenXR VR build

Included:

• Native FNV .fos launch/preflight and exact master-order validation
• FalloutNV.esm runtime bootstrap, player/inventory/equipment import, dialogue/AI/animation/VATS fixes merged through 30b1454
• Scripted BWorlds launch flow documented in nikami-worlds

Use legally owned Fallout: New Vegas data. This is a prerelease: native save/runtime coverage is still being expanded and unresolved state is reported fail-closed rather than silently invented.

OpenMW FNV quest-state runtime — Windows Flat + VR

Verified Windows prerelease from main commit b3b1f5a.

Includes:

• native Fallout: New Vegas Save 330 launch/load path
• exact saved transform, camera, sky/weather, globals, inventory/hotkeys/ammo, and numeric quest runtime state implemented through this commit
• Windows Flat and VR installers built from the same main revision

CI evidence:

• Windows Flat: success
• Windows VR: success
• release workflow: https://github.com/nikamigaming-create/nikami-openmw-lab/actions/runs/29989856509

This remains a prerelease. It is not being represented as complete retail FNV parity; world change forms, reference-valued quest variables, several player runtime domains, and other explicit fail-closed blockers remain under active implementation.

Fallout: New Vegas Flat and VR Windows preview

Fallout: New Vegas ammo + clouds fix (Flat and VR)

Experimental Fallout: New Vegas Flat + VR preview built from main commit 9db62b88f67a079407a175fd8c841fcbd171305e.

Fixes in this build:

• Native .fos inventory ammo lists are materialized as authored AMMO records. Save 331 now restores 100 rounds of standard 5.56mm ammo and the Varmint Rifle can consume them.
• Legacy console additem, removeitem, and equip accept serialized FNV IDs such as FormId:0x100434f.
• FNV automatically selects the retail four-layer meshes/sky/clouds.nif; weather cloud textures are visible again.
• Retail FNV NIF/KF compatibility is enabled automatically.
• README documents exact save-master ordering and direct .fos launch with --load-savegame.

Use the Flat installer for desktop play and the VR installer for OpenXR. Fallout data is not included. This remains an experimental compatibility preview; keep backups of saves you care about.

Validated locally with Save 331 at Goodsprings and by green Ubuntu, Flat Windows, and VR Windows CI.

Fallout: New Vegas experimental Windows preview
