Decompiled DLLs (Ubisoft Leak)

IDA Pro 9.3 Hex-Rays decompiled output from the Ubisoft leak binaries. All are x64 Visual C++ with RTTI intact.

Files

DLL	Size	Purpose
GeomParser_r64.dll.c	4.5 MB	XBG parser/compiler — reads GLM/Collada/GamEx/GLx, outputs .xbg game mesh. Also handles .hkr (Havok ragdoll)
gxasset_release_x64.dll.c	1.7 MB	Asset system (GXAsset) — serialization, node graph, buffer management
DuniaDemo_r64.dll.c	780 KB	Main game DLL (DX11) — entity system, rendering, physics, Lua
DuniaDemo_r64_dx12.dll.c	775 KB	Main game DLL (DX12) — same as above, different rendering backend
Bloomberg.dll.c	1.8 MB	Bloomberg financial data integration (debug/telemetry?)
helix.online_capture_v140.dll.c	1.3 MB	Helix online services — capture/replay, telemetry
Comet_2_Release_x64.dll.c	80 KB	Comet networking — multiplayer, session management
prim_4_10252363098235285984.hkx.c	312 B	Havok primitive (minimal)

GeomParser — XBG Pipeline

GeomParser_r64.dll is the XBG parser/compiler. It reads multiple source formats and outputs the game's runtime mesh format (.xbg).

Input formats:

• .glm — Havok skeletal mesh (Ubisoft's GLM format, MOEG versioned)
• .glx — text-based mesh description
• .dae — COLLADA (import/export)
• GamEx — internal asset format (via CGamExParser)

Output:

• .xbg — compiled game mesh (runtime format, loaded by the engine)
• .hkr — Havok ragdoll (via CHavokParser)

Key classes:

• CGLMParser — reads/writes .glm binary (Ubisoft's Havok-based mesh container)
• CGLxParser — reads .glx text format (human-readable mesh description)
• CColladaParser — reads COLLADA .dae files
• CGamExParser — reads GameX asset format (internal)
• CTriMesh — triangle mesh with clusters, hardware vertices, edge links
• GLMMesh — Havok-style mesh with vertices, faces, normals, UVs, skinning
• CCluster — LOD/rendering cluster

Pipeline:

.glm / .glx / .dae / gamex → GeomParser → .xbg (game runtime)

Skinning/Animation:

• IGeomSkin — skinning interface
• CSkeleton, CBone — skeleton hierarchy
• CBlendShapeMesh — morph targets
• SSecondaryMotionUnitDesc — cloth/hair physics

Cloth:

• SClothWrinkleControlPatchBundle — wrinkle map system
• SSMLimitCollectionDesc — secondary motion limits

Key Classes (DuniaDemo)

The main game DLL reveals runtime systems:

• Entity component system (same as XML entity prototypes)
• Rendering pipeline (DX11/DX12 backends)
• Physics integration (Havok)
• Lua scripting engine
• Audio (Wwise integration)

Multiplayer Backend (PRUDP)

WD1's multiplayer uses Ubisoft's PRUDP (Persistent Reliable UDP) protocol for rendezvous server communication. Debug traces from hook development reveal:

Rendezvous Backend Login:

• RdvBackendLogin_Detour — detour hook function in Disrupt_b64.dll for intercepting the backend login flow
• Sandbox alias: main_dlc
• Sandbox access key: p4BkcPBh
• PRUDP endpoint: prudp:/address=1b-rdv-as-prodel.ubisoft.com;port=21601

Hook Offsets (Disrupt_b64.dll, retail):

Offset	Purpose
0xB965A0	Matchmaking hook (RdvBackendLogin_Detour entry)
0x319CD50	Secondary matchmaking hook

The getSandboxUrl function resolves the PRUDP endpoint for the multiplayer sandbox. The sandbox system allows isolated multiplayer environments (e.g. for DLC content testing).

Source: Debug trace from hook development (wd1_matchmaking.txt, community).

Usage

These are reference decompilations — not meant to be compiled. Use for:

• Understanding function signatures and data structures
• Cross-referencing with Ghidra analysis
• Finding format constants and magic numbers
• Tracing API calls between DLLs
