Wardogs — External Assets Reference

Extracted from cooked game data (Content/ExternalAssets, 147 JSON exports, UE 5.7 build ++Wardogs+Live-CL-516586). Every number below was parsed from the export files by script. Where a field’s meaning is inferred from its name rather than confirmed, the doc says so.

Scope note: This folder is almost entirely building destruction data (Flix/Blueprints/**), plus two damage-tag whitelists and one VFX mapping. It holds no weapons, economy or progression data. All 147 files parsed without error.

Season 02 update (2026-10-15)

  • Added: 47 files (26 building definitions and 21 decorator definitions). New in Bakurani: six residential houses and one swimming-pool building, with their decorators. New in Commercial: 14 Highstreet buildings with 13 decorators, 4 Hospital buildings with 4 decorators, and one WorkShop building with one decorator.
  • Removed: none.
  • Building definitions: 48 → 74. Chunks 13,087 → 22,137; required-mesh entries 2,364 → 3,943; junctions 6,875 → 13,953; chunks with a prefab reference 330 → 343.
  • Decorator definitions: 49 → 70. Cosmetic entries 25,927 → 29,890; authoritative entries 5,902 → 8,068; actor decorator entries 1,427 → 1,989; actor-class references 209 → 279.
  • DA_Warehouse_Small_02a: 30 → 29 chunks (required-mesh RefCount sum 30 → 29).
  • D_Residential_House_03: chunks with a prefab 6 → 2. D_Residential_House_04: 17 → 12.
  • House decorators, cosmetic entries: D_Decorator_D_Residential_House_01 448 → 470, _03 470 → 492, _04 438 → 459, _05 435 → 455. Required cosmetic meshes: _01 98 → 101, _03 106 → 107, _04 95 → 97, _05 99 → 100.
  • Actor decorator entries: DA_ApartmentBuilding_Decorator_01c 103 → 104, D_Decorator_Shop_01 16 → 17, D_Decorator_Residential_Bungalow_02 22 → 23.
  • Madrid reskins: the same 7 of 9 pairs share chunk IDs. The two House pairs (Madrid 01 and 03) still differ from Bakurani.
  • SaveIDs changed on 97 existing files. Per-chunk prefab hashes and primitive-data values also changed; those fields are not decoded here, so no table records them.

Full before/after list: Season 2 Changes → World, Visuals & Audio.

1. File Inventory

Type Files Role (as read)
BHDestructionBuildingDefinitionDataAsset 74 Destructible building: chunk layout, junctions, required meshes, Niagara refs

Folders: Flix/Blueprints/Bakurani (30 buildings), Flix/Blueprints/Madrid (10), Flix/Blueprints/Industrial (14), Flix/Blueprints/Commercial/Office (1), Flix/Blueprints/Commercial/Highstreet (14), Flix/Blueprints/Commercial/Hospital (4), Flix/Blueprints/Commercial/WorkShop (1), Flix/DataAssets, and Flix/VFX/.../DataChannels.

2. Building Definitions (BHDestructionBuildingDefinitionDataAsset, 74 assets)

Totals across all 74: 22,137 chunks, 3,943 required-mesh entries, 13,953 junctions, 343 chunks with a prefab reference.

2a. Top-level fields

Property Shape Meaning (confidence)
SaveID GUID string Building identifier. Madrid copies get a different SaveID from their Bakurani source (checked on apartment and house pairs). Purpose not confirmed.
RequiredMeshes list of {StaticMesh, MaterialOverrideArray, PhysicalMaterialOverride, MeshCenter, RefCount, StringISMOverrides} Static meshes the building needs. RefCount is how many chunks use it. MeshCenter is the pivot offset (high confidence, from field names).
ChunkData list of chunk records One record per destructible piece. Fields in 2b.
ChunkIDLookupMap list of {Key: ChunkId, Value: index} Same length as ChunkData. Maps chunk GUID to array index (confirmed by inspection on DA_Warehouse_Small_Hut_02a).
JunctionData list of {JunctionLocation, JunctionEdgeData[]} Points where several chunk edges meet. Each edge has ChunkIndex and EdgePieceData.EdgeOffset. Absent on every industrial building and on the Factory Awnings.
RequiredNiagaraAssets list of {NiagaraAsset} Niagara systems referenced by index, e.g. NS_FullWallBreak_1, NS_BalconyBreak. 0 to 2 per building.

2b. Chunk record fields

Field Meaning (confidence)
ChunkId GUID string. The key used by ChunkIDLookupMap and by decorator OwningChunkIDs.
Transform Rotation, Translation, Scale3D. Units are not stated in the dump (probably cm, the UE default).
AssetRefIndex Index into RequiredMeshes, -1 when none (inferred from name).
NiagaraAssetRefIndex Index into RequiredNiagaraAssets, -1 when none (inferred from name).
StructuralSupports.VitalConnections / ProportionalConnections Chunk-to-chunk support links as index lists. “Vital” probably means the chunk falls if the link breaks; “proportional” probably means load is shared. Both inferred from names, not confirmed.
EdgePieces Edge geometry used when the chunk breaks. Counted per building in section 2c.
NiagaraBespokeEffectFormat Enum: NoBespokeFormat, Wall2m, Wall4m, Wall6m. Picks a bespoke debris effect by wall length. On DA_ApartmentBuilding_01_a, Wall4m (481) is the most common non-default format.
NiagaraDataChannelParameters Debris tags: DebrisMeshType (Wall, Ceiling, Roof, Balcony, Generic), DebrisShape (e.g. Wall_4m, Corner_J_2m_x_2m, Roof_Slope_4m_x_4m, or None), DebrisMaterial (Concrete, Wood, Metal).
ChunkTraits Present on every chunk, empty on every sampled chunk.
ChunkCustomPrimitiveData Four floats (e.g. 0.4, 0.12, 0.085, 1.0). Meaning not stated, probably shader parameters. Not decoded.
Prefab / PrefabHash Optional prefab class reference (e.g. CP_ModKit04_Roof_Panel_Short_2m_A). Mostly on apartments (47, 23, 36 chunks in the three Bakurani apartment blocks), Office (15), houses and bungalows (0 to 17 each), Highstreet buildings (0 to 3 each) and hospitals (1 each).
AudioPhysMaterialArray Audio physical materials. Empty on sampled chunks.
Properties Integer flag field. Non-zero on 882 of 1,550 chunks in DA_ApartmentBuilding_01_a. Meaning not confirmed.

2c. Per-building table

Columns: mesh entries (RequiredMeshes count), unique StaticMesh names, chunks, junctions, Niagara refs, chunks with a prefab, total edge pieces, vital and proportional connections (summed over chunks), and RefCount summed over all required meshes.

Reading the table:

  • DA_ApartmentBuilding_01_b is the largest building: 1,979 chunks, 1,115 junctions.
  • Industrial buildings have no junctions and no edge pieces, but many chunks. They break into flat pieces with no junction layer.
  • The Madrid apartment and bungalow definitions match their Bakurani sources chunk for chunk (section 7).

3. Decorator Definitions (BHDestructionBuildingDecoratorDefinitionDataAsset, 70 assets)

Totals across all 70: 29,890 cosmetic decorator entries, 8,068 authoritative decorator entries, 1,989 actor decorator entries, 279 actor-class references.

3a. Field meanings

Property Shape Meaning (confidence)
SaveID GUID string One per decorator asset.
RequiredActorClasses list of {SoftActorClass: {AssetPathName}, RefCount} Soft references to actor classes the decorator spawns, to be preloaded.
ActorDecoratorData list Spawned actor placements. Fields: Transform, ActorClassRefIndex (index into RequiredActorClasses), OwningChunkIDs, StringTemplateOverrides, Prefab. Likely doors, windows and decals (inferred from the classes in 3c).
CosmeticDecoratorData list Visual-only pieces. Fields: OwningChunkIDs (building chunks it attaches to), Transform, AssetRefIndex, ActorClassRefIndex, NiagaraAssetRefIndex, SoundEmitterAssetRefIndex, DecoratorNiagaraDataChannelParameters, plus an unnamed GUID-keyed list. The largest collection in the set.
AuthoritativeDecoratorData list Same shape as cosmetic data. The name suggests server-authoritative pieces (doors, smashable windows). Not confirmed by code.
RequiredCosmeticMeshes / RequiredAuthoritativeMeshes list of {StaticMesh, ...} Preload lists, same shape as building RequiredMeshes.
RequiredNiagaraAssets list Niagara systems, on only a few decorators.

Decorator-to-building linkage is by name pattern (DA_X pairs with DA_Decorator_X or D_Decorator_X) and by the OwningChunkIDs GUIDs. The dump has no explicit building reference on the decorator.

3b. Per-decorator table

Columns: actor-class references, ActorDecoratorData count, CosmeticDecoratorData count, AuthoritativeDecoratorData count, preload-list lengths for cosmetic and authoritative meshes, and Niagara refs.

These are soft references (AssetPathName). Most are doors (BP_InteractableDoor_*, B_Door, BP_Interactable_HospitalDoor_*), smashable window and balcony blueprints (B_Smashable*Window, B_SmashableApartmentBalconyDoor), and decals (MI_Apartment_EdgeDirt_*, BP_Apartment_StairStripeDecal_*, BP_WaterStain_Decal_01a, BP_Debris_Decal_01a). One script class, /Script/WDGame.WDDestructionAmbienceVolume, is used 61 times.

4. Damage-Tag Whitelists (BHDestructionDecoratorMeshDamageTagsDataAsset)

Asset Entries Content
DA_DestructionDecoratorBallisticsTagWhitelist 68 Each entry is Key (a /Game/... static mesh path: decorative room props such as SM_DecorativePlate01, and Megascans assets) and Value (a list of damage-tag strings). 67 entries carry 13 tags. One entry (S_Wooden_Floor_Lamp_vi5hbjgga_high_Var2) carries 12.
DA_DestructionDecoratorExplosiveTagWhitelist 0 Header only, no Properties. Empty.

The 13 distinct ballistic tags (all Meta.Damage.Bullet.*): 9mm, 12g, 30mm, 308Win, 338Nor, 45ACP, 45Colt, 50Cal, 545mm, 556mm, 762mm, 762x51mm, 762x54mm. 67 of the 68 meshes carry all 13.

Meaning, inferred from the name: a mesh gets bullet decoration only if the incoming damage tag is on its list. The explosive whitelist is empty, so no mesh in this export is whitelisted for explosive damage tags.

5. Chunk-Classification VFX (D_BuildingVFX, BHDestructionBuildingVFXDataAsset)

Entry Niagara data channel Houdini point caches
1 NDC_WallDebris 8 (e.g. SM_Wall_2m_points)
2 NDC_RoofDebris 6 (e.g. SM_Roof_Bottom_A_points)
3 NDC_CeilingDebris 0
4 NDC_BalconyDebris 2 (e.g. Balcony_B_points)
5 NDC_GenericDestruction 0

ChunkClassificationEffects maps a chunk class to a Niagara data channel and to pre-baked Houdini point caches. The dump does not show how a chunk gets its class. The DebrisMeshType tag in section 2b is the likely selector, but that is not confirmed.

6. How the Pieces Combine

  1. A building definition describes the chunks, their connections (vital and proportional), junctions and the meshes they use.
  2. A decorator definition with the same name family attaches props to those chunks. Each cosmetic or authoritative entry lists its OwningChunkIDs, so it breaks with the chunks it sits on.
  3. Debris look is chosen per chunk from NiagaraDataChannelParameters (mesh type, shape, material), and from NiagaraBespokeEffectFormat for wall lengths.
  4. Bullet decoration on a mesh is gated by its damage-tag whitelist. The ballistic list covers 68 meshes. The explosive list is empty.

7. Madrid Reskins

The Flix/Blueprints/Madrid folder re-uses Bakurani geometry under new SaveIDs. Chunk-ID lists were compared pairwise:

Madrid asset Bakurani source Same chunk IDs
DA_Ozeti_ApartmentBuilding_01_a DA_ApartmentBuilding_01_a yes
DA_Ozeti_ApartmentBuilding_01c DA_ApartmentBuilding_01c yes
D_Residential_Bungalow_Madrid_01 D_Residential_Bungalow_01 yes
D_Residential_Bungalow_Madrid_02 D_Residential_Bungalow_02 yes
D_Residential_Bungalow_Madrid_03 D_Residential_Bungalow_03 yes
D_Residential_House_Madrid_01 D_Residential_House_01 no (148 vs 143 edge pieces)
D_Residential_House_Madrid_03 D_Residential_House_03 no
D_Residential_House_Madrid_04 D_Residential_House_04 yes
D_Residential_House_Madrid_05 D_Residential_House_05 yes

So 7 of 9 pairs share chunk IDs. D_FootballStadium_Building_01a (Madrid, 463 chunks, no junctions) has no Bakurani source in this folder.

8. Still not pulled / Limitations

  • Unresolved property names. Some properties appear only as GUID-style keys. On every RequiredMeshes entry the value is EBHDestructionCPDInputStyle::Building. Cosmetic decorator entries carry an unnamed list. Their meaning is not known from this export.
    • SDK (2026-10-16): EBHDestructionCPDInputStyle is a 3-value enum: Building = 0, TrimSheet = 1, None = 2. The doc’s observation that every RequiredMeshes entry carries Building is consistent with the enum’s design — building meshes get the Building style, trimsheet meshes get TrimSheet. The GUID-style keys on cosmetic decorator entries remain unresolved via SDK (Dumper-7 could not label them).
  • Bit and enum meanings not decoded. The chunk Properties flag, ChunkCustomPrimitiveData (four floats) and ChunkTraits (empty in every sample) are reported as found, not interpreted.
  • Connection semantics inferred. “Vital” and “proportional” support links are read from property names. Runtime behaviour is not confirmed.
  • Decorator-to-building link is by name. Only the OwningChunkIDs GUIDs give a hard link, and they were spot-checked, not checked for every decorator.
  • Explosive whitelist is empty. Whether that is intended or a cook artifact is not known.
  • One ballistic entry with 12 tags. The mesh S_Wooden_Floor_Lamp_vi5hbjgga_high_Var2 is missing one of the 13 tags. Which one was not checked.
  • Units. Transform values are reported raw. The dump does not state units.
  • Houdini point caches not expanded. Section 5 gives names and counts only.
  • Large files summarised, not read entry by entry. The largest file (DA_ApartmentBuilding_01_b, about 7.5 MB) was parsed in full by script, and its chunk arrays were summarised rather than inspected individually.
