Far Cry (Dunia engine)

• XBG Format Notes (FC5 vs FC6) - GMESH/IMESH magic vs Disrupt GEOM, SDOL/LODS chunk layout, FC5 stride 40 vs FC6 richer descriptor table, packed/quantized vertices

• Shader system lineage (FC1 → FC6) - FC1 runtime-preprocessed text scripts (Cg/D3DX, gen-mask defines) → Disrupt/FC6 offline ShaderCompiler2 DXBC + <technique> XML; FC1 render-state tokens map 1:1 to FC6 shadersobj.dat elements

• .cgf chunk → .xbg lineage - FC1 CryChunkedFile ChunkTypes enum + CHUNK_HEADER{Type,Version,Offset,ID} is the ancestor of the FC5/FC6 XBG chunk chain; FC1 Mesh/Node/Mtl/BoneNameList/BoneAnim chunks map to SULC/EDON/LTMR/DNKS/ITOM; ResourceCompiler origins; .pak (not .dat/.fat) archive in FC1

• Raw XeNTaX extraction - source threads (2018–2023): FAT v10→v11 change, hook/filelist filename recovery, FC6 XBG short-signed XZY verts per-LOD, SDOL chunk struct, FC6Model.exe + .bwsk/.dpdx facial-bone workflow

• File lists (hash → name) - concatenated/ raw accumulation → OSM FarCry*-File-Lists submodules via RebuildFileLists; CRC64 path hashing, FAT v11 decode, positional install-path usage

• Runtime capture (FC6) - FileHook (log every path the game opens, then hash-match vs the fats) + DumpModule (snapshot the Denuvo/VMProtect-packed DLL after runtime unpack for real disassembly)

• MAB animation format - version bytes per game (FC2–FC6), FC3 16-byte vs FC5/FC6 100-byte header, 9-section layout, 48-bit compressed quaternions (sqrt-W reconstruction), mystery-byte bitmask, anchor data structure, frame interpolation (FC4+); sources knockout.chat/thread/55079, PY-DuniaAnimationExtractor wiki, FCBConverter source

• Far Cry modding (community docs) - FCModInstaller workflows (package/replace/option/template from the .docx) + community guides (FC4 materials/suppressors, FC5 outfit BWSK, FC6 Wwise music, FOV hex editing, StimTypes)
