# Wowee Open Format Specification v1.2
|
||
|
||
Novel file formats for custom WoW zone content. No Blizzard IP.
|
||
|
||
## WOT — Wowee Open Terrain (JSON metadata)
|
||
- Extension: `.wot`
|
||
- Contains: tile coords, texture list, per-chunk layers/holes, water data,
|
||
doodad placements (M2 objects), WMO placements (buildings)
|
||
- Key: `"format": "wot-1.0"`
|
||
- Placement fields: `doodadNames[]`, `doodads[]` (nameId, uniqueId, pos, rot, scale, flags)
|
||
- WMO fields: `wmoNames[]`, `wmos[]` (nameId, uniqueId, pos, rot, flags, doodadSet)
|
||
|
||
## WHM — Wowee HeightMap (binary)
|
||
- Extension: `.whm`
|
||
- Magic: `WHM1` (0x314D4857)
|
||
- Layout: magic(4) + chunkCount(4=256) + vertsPerChunk(4=145) + per-chunk data × 256
|
||
- Per-chunk: baseHeight(4 float) + heights[145](580 = 145 floats) + alphaSize(4) + alphaData(alphaSize bytes)
|
||
- Alpha data: raw alpha blend maps for texture layers (same format as ADT MCAL)
|
||
- Backward compatible: older WHM files without alpha data still load (alphaSize=0)
|
||
|
||
## WOM — Wowee Open Model (binary)
|
||
- Extension: `.wom`
|
||
- Magic: `WOM1` (0x314D4F57) static, `WOM2` (0x324D4F57) animated, `WOM3` (0x334D4F57) multi-batch
|
||
- Layout: magic(4) + vertCount(4) + indexCount(4) + texCount(4) + boundRadius(4) + boundMin(12) + boundMax(12) + nameLen(2) + name + vertices + indices(uint32 each) + [pathLen(2) + path] × texCount
|
||
- WOM1 Vertex: position(vec3=12) + normal(vec3=12) + texCoord(vec2=8) = 32 bytes
|
||
- WOM2/WOM3 Vertex: + boneWeights(4) + boneIndices(4) = 40 bytes
|
||
- WOM2/WOM3 trailing block: boneCount(4) + [keyBoneId(4) + parentBone(2) + pivot(12) + flags(4)] × bones
|
||
+ animCount(4) + [id(4) + duration(4) + speed(4) + per-bone-keyframe-block] × anims
|
||
- Keyframe: timeMs(4) + translation(12) + rotation(16) + scale(12) = 44 bytes
|
||
- WOM3 Batches (after WOM2 trailing block): batchCount(4) + [indexStart(4) + indexCount(4) + textureIndex(4) + blendMode(2) + flags(2)] × N
|
||
- WOM3 blendMode: 0=opaque, 1=alpha-test, 2=alpha, 3=add, 4=mod, 5=mod2x, 6=blendAdd, 7=screen
|
||
- WOM3 flags: bit 0 = unlit, bit 1 = two-sided, bit 2 = no z-write
|
||
- Backward compatible: WOM1 files load without bone/animation data; WOM3 falls back to single-batch when batches block missing
|
||
|
||
## WOB — Wowee Open Building (binary)
|
||
- Extension: `.wob`
|
||
- Magic: `WOB1` (0x31424F57)
|
||
- Layout: magic(4) + groupCount(4) + portalCount(4) + doodadCount(4) + boundRadius(4) + nameLen(2) + name + groups + portals + doodads
|
||
- Group: nameLen(2) + name + vertexCount(4) + indexCount(4) + texCount(4) + outdoor(1) + boundMin(12) + boundMax(12)
|
||
+ vertices(pos+normal+uv+color = 48 bytes) + indices(uint32) + texPaths(prefixed) + materialCount(4) + materials
|
||
- Material: pathLen(2) + texturePath + flags(4) + shader(4) + blendMode(4)
|
||
- Doodad: pathLen(2) + modelPath + position(12) + rotation(12 euler degrees) + scale(4)
|
||
- Portal: groupA(4) + groupB(4) + vertexCount(4) + vertices(12 bytes each)
|
||
- toWMOModel restoration:
|
||
- Materials are deduplicated across all groups by (texture, blend, flags)
|
||
- Texture paths .png → .blp (renderer's PNG override is keyed on .blp)
|
||
- Outdoor flag → WMO group flag bit 0x08
|
||
- Portal vertices reconstruct MOPR refs for groupA / groupB
|
||
- Doodad euler degrees → glm::quat using glm::eulerAngles convention
|
||
- Default `Set_$DefaultGlobal` doodadSet emitted when doodads present
|
||
|
||
## WCP — Wowee Content Pack (archive)
|
||
- Extension: `.wcp`
|
||
- Magic: `WCP1` (0x31504357)
|
||
- Layout: magic(4) + fileCount(4) + infoJsonSize(4) + infoJSON + [pathLen(2) + path + dataSize(4) + data] × N
|
||
- Info JSON includes categorized file list (terrain/model/building/texture/data)
|
||
|
||
## zone.json — Map Definition
|
||
- Replaces WDT
|
||
- Fields: `mapName`, `displayName`, `mapId`, `biome`, `baseHeight`
|
||
- `hasCreatures`, `description`, `tiles` array, `files` map
|
||
- `doodadNames[]`, `doodads[]`, `wmoNames[]`, `wmos[]` for placed objects
|
||
- `editorVersion` for compatibility tracking
|
||
|
||
## JSON DBC — Data Table Replacement
|
||
- Replaces binary DBC files
|
||
- Format: `{"format": "wowee-dbc-json-1.0", "records": [...], "fieldCount": N}`
|
||
- Records are arrays of mixed types: integers, floats, strings
|
||
- Client loads via DBCFile::loadJSON() when found in custom_zones/ or output/
|
||
|
||
## PNG Textures — Texture Replacement
|
||
- Replaces BLP texture files
|
||
- Standard PNG format, loaded by client's texture override system
|
||
- Editor auto-converts BLP→PNG on export via stb_image_write
|
||
|
||
## WOC — Wowee Open Collision (binary)
|
||
- Extension: `.woc`
|
||
- Magic: `WOC1` (0x31434F57)
|
||
- Layout: magic(4) + triCount(4) + tileX(4) + tileY(4) + boundsMin(12) + boundsMax(12) + triangles
|
||
- Triangle: v0(12) + v1(12) + v2(12) + flags(1) = 37 bytes
|
||
- Flags: 0x01=walkable, 0x02=water, 0x04=steep, 0x08=indoor
|
||
- Generated from terrain heightmap with slope classification (50 deg threshold)
|
||
- Respects terrain holes (skips triangles in hole regions)
|
||
- WoweeCollisionBuilder::addMesh appends placed WMO group geometry
|
||
(transformed into world space, slope-classified) so collision covers
|
||
buildings as well as terrain.
|
||
|
||
## Terrain Stamps (.json)
|
||
- Portable terrain feature snapshots (mountains, craters, etc.)
|
||
- Format: `{"format": "wowee-stamp-1.0", "vertices": [[dx, dy, height], ...]}`
|
||
- Can be saved/loaded across zones and sessions
|
||
|
||
## Open Format Scoring (0-7)
|
||
1. WOT terrain metadata present
|
||
2. WHM heightmap with valid magic
|
||
3. zone.json map definition
|
||
4. PNG textures present
|
||
5. WOM models with valid magic
|
||
6. WOB buildings with valid magic
|
||
7. WOC collision mesh with valid magic
|
||
|
||
## SQL Server Export
|
||
- AzerothCore-flavored INSERT statements for: `creature_template`, `creature`,
|
||
`creature_addon`, `waypoint_data`, `quest_template`, `creature_queststarter`,
|
||
`creature_questender`.
|
||
- Coordinates: editor render coords are converted to WoW canonical via
|
||
`core::coords::renderToCanonical` (X/Y swap) before write.
|
||
- Orientation: editor degrees from +renderX (west) → WoW radians from +X (north).
|
||
Conversion: `wowYaw = π/2 - editorYaw` then normalised to [0, 2π).
|
||
- Quest objectives: KillCreature targets fill RequiredNpcOrGo[1..4]; CollectItem
|
||
targets fill RequiredItemId[1..6]. Target ID parsed from objective.targetName.
|
||
- Quest givers/turn-in NPCs: written as `creature_queststarter` /
|
||
`creature_questender` rows linking npc.id ↔ quest.id.

||
