Disrupt Engine — Asset Pipeline Format Mapping

Source: OCR of WDL dev pipeline reference (wdl_format_info.txt), cross-referenced with community findings.

The Disrupt engine converts authoring formats into runtime binary formats during the build process (PreparePlatformData64.exe). Here is the mapping from source/authoring format to compiled/runtime format.

Format Conversions

Authoring Format	Runtime Format	Description
material.xml	.material.bin	Material descriptors (TAM v7 binary, magic 0x004D4154)
.mac + .markup	.mab + .markup.bin	Animation clips — MAC (source binary) + markup (XML events) compiled via CMarkupCompiler to MAB (Oodle-compressed runtime) + markup.bin (10-byte header)
.seq	.cseq	Cutscene sequences (QES binary format)
_move.xml	_move.bin	Movement/locomotion data
_markup	_markup.bin	UI markup data
.1ft	.xIf	Physics fixture data
.tree_xml / .impostor.xml	.bin	Vegetation tree + impostor data
.bik	.bik / .biklight	Bink video (light variant for pre-rendered sequences)
.fba / .animset	.dpax	Animation blend trees / animation sets
-dpds	_dpdx	Depload dependency data (compiled)

Resource Class Registry (WD2 editor strings)

Extracted from WD2 memory dumps (noah Gooder, Dec 2018). These define the engine's internal resource type system — which source extensions map to which compiled runtime extensions:

Resource Class	Source Extensions	Target Extension	Notes
CActorDialogPackResource	(none)	.stimuli.dsc.pack	Dialog stimulus packs
CAnimationTrackCollectionResource	.animtrackcol.xml	.animtrackcol.rml	Animation track collections
CBinkResource	.bik	.bik	Bink video (passthrough)
CFuzzyLogicTableResource	.fzl.xml	.fzl	Fuzzy logic tables
CGeometryResource	.glm .dae .gamex	.xbg	3D models — GLM (text), DAE (Collada), GameX (binary) are all geometry source
CMaterialResource	.material.xml	.material.bin	Material descriptors
CModelResource	.model	.model	Model descriptors (bind XBG + material)
CMoveResource	.move.xml	.move.bin	Movement/locomotion data
CNomadResource	.impostor.xml	.impostor.bin	Vegetation impostors
CNomadResource	.tree.xml	.tree.bin	Vegetation trees
CPhysResource	.hkr	.hkx	Physics (Havok) — optional .gamex source
CPhysResource	.tree.hkr	.tree.hkx	Vegetation physics
CSequenceResource	.seq	.cseq	Cutscene sequences (deps: .naseq .liseq .auseq .fxseq .prseq)
CSkeletonResource	.skel.xml	.skeleton	Skeleton definitions
CSoundResource	(none)	.bnk	Sound banks
CStateMachineResource	.gosm.xml	.gosm.xml	Game object state machines (passthrough)
CTextureResource	.png .dds .hdr	.xbt	Textures
CWorldLoadingUnitResource	.data.fcb	.data.fcb	World loading units (passthrough)

Editor Indexer Types

The engine scans for assets via ToIndex entries in the build pipeline:

Indexer Type	Extensions	FolderPath	Notes
GLMToIndex	.glm	graphics	Geometry source files
HkrToIndex	.hkr	graphics	Havok physics
TextureToIndex	.png	graphics;ui;editor	Texture sources (SmallMax=16K, BigMax=4M)
NomadToIndex	.tree.xml	graphics	Vegetation
EntityToIndex	.xml	worlds;missions;entitylayers	World entities
ResourceFileToIndex	.dae	graphics;editor\scenes	Collada geometry (XmlInvokeDep)
ResourceFileToIndex	.gamex	graphics	GameX binary geometry
ResourceFileToIndex	.lua	domino	Lua scripts
ResourceFileToIndex	.markup	graphics;animations	Animation markup (TriggerKey=MarkupToAnim)
ResourceFileToIndex	.dds	graphics;ui;editor	DDS textures
ResourceFileToIndex	.seq .naseq .anseq .liseq .fxseq	sequences	Cutscene sequences
ResourceFileToIndex	.skel.xml	graphics	Skeleton XML
ResourceFileToIndex	.animtrackcol.xml	animations	Animation tracks
ResourceFileToIndex	.stimuli.dsc	dialog	Dialog stimuli
DominoToIndex	.domino	domino	Domino scripts
StateMachineBlobToIndex	.xml	engine\scripts\game\objects\pawn\stateMachine	Pawn state machines
XmlDepToIndex	.xml	graphics;editor\scenes	XML dependencies (FileExtensions: glm;hkr;gamex;dae)

Key insight: .dae and .gamex are alternative geometry source formats — same CGeometryResource class as .glm. The GLM text parser should handle all three with format detection (GLM = text tabs, DAE = Collada XML, GameX = binary).

Other Asset Categories

Category	Notes
Road/spline	Geometry + loft (graphics/physics)
Sound banks	.bnk / .spk audio containers
Character customization	Graphickit parts, clothing definitions
Lua scripts	Compiled to bytecode (not source — game reads compiled)
World/terrain	Terrain chunks, navmesh, world generation
Specialized Havok variants	Physics data (collision, ragdoll, vehicle)
AI/world systems	Behavior trees, spawn tables, traffic patterns

Key Notes

• .fx shader source is NOT compiled — the game reads compiled shaders from shadersobj.dat, not .fx source from shaders.dat
• .material.bin uses TAM v7 — magic bytes 54 41 4D 00 (little-endian). Beta builds used v5 big-endian (00 4D 41 54)
• .cseq cutscenes are QES (Quake Engine Sequence) binary format — 307 files in WD1 unpacked data
• Lua scripts are compiled to bytecode at build time — decompilation required for editing
• Depload (_dpds → _dpdx) is the dependency preload manifest — see Depload Format
