- the step in the water at the shore, which travelled with you as you walked: `WATER_BIAS` (−2e4) exists to give the water pass its sort slot, and bevy's `StandardMaterial` also packs that f32 into the rasterizer's depth bias, so every water surface in the game shipped with a −20000 depth pull — on the one world surface that meets the ground at a grazing angle over tens of yards that does not settle a tie, it moves the waterline, and a float depth buffer's bias unit doubles at every exponent boundary, so two water triangles either side of one stopped agreeing about where the shore is, at a fixed distance from the eye; the bias is out of the rasterizer (a ~17 px jog at the reported Stranglethorn beach, present before and absent after) - the foam wake went dull under the next water chunk and painted onto dry sand: it sorted against ONE water surface with a coplanar epsilon (the chunk 33 yd nearer the eye outranked it thirty times over, while the reference drains every liquid queue before it draws foam, `0x6816d0`), and its coplanar settle was a 0.03 yd geometric LIFT, which on a 29% beach is 0.10 yd of dry sand painted and proportionally more on every flatter shore; it is a rung above the whole water band now and sits exactly on the plane, and the RE on its depth state came back: a depth-buffer bias (`footstepBias × [0x810390]`), depth-tested LEQUAL with write off — the "−2048 GL units polygon offset" our comment justified the lift with existed nowhere in wow-re - a unit standing in a room the camera's chain does not reach wore the building's fog while the walls around it wore the scene's: the reference's unit test has a second conjunct (`[P+0x98]`, the same `[0xca7f00]` chain gate the walls use), so the attach ray now returns the room it claimed and the gate is re-read every frame because it moves with the CAMERA — at Shadowfang, from inside the pinned room, three true interiors are in frame across the courtyards and a mob in g13, 91 yd out, wore the keep's teal at ~84% against a scene fog of ~3% - two instruments for the shore class of report: `water_here <map> <x> <y>` reads a shoreline offline (the wet-cell lattice, the plane on it, the terrain under it, and the four scans that tell an authored defect from a rendered one), and `WOW_CAPTURE=waterfx WOW_WFX_AT=x,y,z` wades the foam rig in the REAL streamed water at a pin, where the synthetic square had no bank to clip against Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
Important
Issues and pull requests are closed here. benilla is a solo project developed in a private tree; this repo is its export, published as squashed snapshots, so a PR here has nothing to land on. The best way to contribute is to join the Discord and report the bugs you find. Questions and ideas are welcome in the same place.
benilla speaks the original 1.12.1 protocol, so it connects to any server the real client could, and reads its game data at runtime from your own 1.12.1 install. Every file format and the network protocol are implemented from scratch, with no original client code, no third-party WoW crates, and no bundled game assets.
What works
- Formats: readers for the full asset stack (MPQ patch chain, BLP, DBC, ADT/WDT/WDL, M2, WMO), wired into Bevy as an asset source.
- World: streamed terrain out to the horizon, portal-culled WMOs with interior lighting, doodads and ground clutter, swimmable liquids, sky and weather, and the client's own day/night lighting, fog and gamma passes.
- Models: GPU-skinned M2s with the full animation controller, a near feature-complete particle system, ribbons, and animated gameobjects from doors to lifts.
- Characters: customization end to end, the armor texture composite, weapons with sheathing and enchant glows, shapeshift forms, stealth and mounts.
- Movement: a WoW-feel controller, networked movement in both directions, the server-granted modes from slow fall to roots, a follow camera with collision, boats, zeppelins and taxi flights.
- Networking: SRP6 auth through world-session crypto, the object mirror into the ECS, and live wire coverage from movement and chat through spells, party, quests, mail, trade, vendors, bank, loot, the auction house and PvP honor.
- UI: a from-scratch FrameXML + Lua engine driving the built-in interface, from the login and
character screens through the full HUD, the classic windows (guild, macros and key bindings
included), chat, nameplates, floating combat text and tooltips; third-party addons load from
a
benilla-config/AddOns/folder beside the executable (partial: AtlasLoot and Bagnon run, see below). - Combat: melee on the faithful swing law, ranged and Auto Shot, casting with GCD and cooldowns, combo points, crowd control that really holds you, and the spell visual pipeline.
- Audio: music, ambience and SFX under the client's own selection and crossfade rules, with interior and underwater transitions and zone reverb.
Where it's going
benilla is done when a 1.12.1 player can do everything here that they could in the original client, it looks and feels the same, and it runs from a download on Windows, Linux and macOS. No dates; the order is what is likely, not a promise.
- Battlegrounds and meeting stones, then the long tail of small features that separates a working client from a finished one.
- Addons, options and performance, ongoing.
- The no-brainer fixes from VanillaFixes, SuperWoW and the like.
- Playable downloads for Windows, Linux and macOS. Linux first.
Not planned: other expansions or client versions, Warden (anticheat).
Running it
You need a 1.12.1 (build 5875) client install for game data, a vanilla server to connect to, and stable Rust. Any 1.12.1 core works; vmangos is what development runs against, and cMaNGOS and the rest speak the same protocol.
WOW_DATA=/path/to/WoW/Data cargo run --release -p benilla
The server defaults to localhost:3724, the stock realmd auth port. Point WOW_HOST
at any IP or hostname, appending the auth port if yours is remapped
(WOW_HOST=play.example.com:5000). Credentials go in at the login screen, or set WOW_USER /
WOW_PASS to skip it.
Early inspiration and file format guidance came from the wowemulation-dev community, and warcraft-rs in particular.
benilla is an independent fan project, not affiliated with or endorsed by Blizzard Entertainment.
It ships no Blizzard content — no art, models, sounds, maps, MPQ contents or FrameXML; you
provide your own legally obtained 1.12.1 client. The interface code under
crates/benilla-app/assets/ui/ is ours, written to the client's own layout and API names so that
the windows look right and 1.12.1 addons find the names they expect.
