WD2 Model Hash Mappings

Model hashes map CRC64 identifiers to XBG geometry paths. These are the fileModel values used in entity XML files (WD2_*.xml) to reference 3D models.

Format​

Each line maps a model hash to its XBG path:

XML_FILE MODEL_HASH CRC64_BYTES XBG_PATH
W2BK_Vegetation.xml 0x80000007defa4dd1.model 7D E4 FA DE ... graphics\_geometries\vegetation\static\american_aloe\american_aloe_kit_01_med_01_bk.xbg

Fields:

  • XML source file — entity definition XML that references this model
  • Model hash — 0x8000000 prefix + CRC64 of the XBG path (WD2 uses CRC64, not FNV1a32)
  • CRC64 bytes — raw 8-byte hash in hex
  • XBG path — backslash-separated path to the .xbg geometry file

Hash scheme​

WD2 model hashes use CRC64 with mask: (hash & 0x1FFFFFFFFFFFFFFF) | 0xA000000000000000.

def model_hash(path: str) -> int:
 text = path.replace("/", "\\").lower()
 num = 14695981039346656037
 for c in text:
 num *= 1099511628211
 num ^= ord(c)
 return (num & 0x1FFFFFFFFFFFFFFF) | 0xA000000000000000

Resolving a hash​

Gibbed resolves the model hash from the path itself, so no hash table needs publishing: the XBG paths are already in the WD2 archive file lists, and the hash is recomputed from the path whenever a tool needs it.

The hash-to-path tables are a local dump. To rebuild them, read the fileModel values out of the WD2_*.xml files you unpacked and index them against the graphics\_geometries\... paths in the same unpack; each row is the entity XML that references the model, the fileModel hash, the raw 8-byte hash and the XBG path.
