From b439f12c364205a656ac6f14dcab30f0e9e3115c Mon Sep 17 00:00:00 2001 From: Kelsi Date: Tue, 5 May 2026 16:23:22 -0700 Subject: [PATCH] fix: WOM2 bone data in client renderer, WOM tests, docs update MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Fix WOM→M2Model conversion: copy boneWeights/boneIndices from WOM2 vertices (was dropping skeletal binding data, breaking animation) - Copy bone hierarchy and animation sequences from WOM2 to M2Model so animated WOM2 models render with proper skeletal deformation - Add 3 WOM format tests: WOM1 binary structure, WOM2 magic check, invalid magic rejection (6 new assertions) - CHANGELOG: document WOM1/WOM2 animated model support - README: clarify WOM1 (static) vs WOM2 (animated) models - 334 total assertions across 87 test cases --- CHANGELOG.md | 2 +- README.md | 2 +- src/rendering/terrain_manager.cpp | 21 ++++++++++ tests/test_open_formats.cpp | 69 +++++++++++++++++++++++++++++++ 4 files changed, 92 insertions(+), 2 deletions(-) diff --git a/CHANGELOG.md b/CHANGELOG.md index a28bc8b9..3d8d0600 100644 --- a/CHANGELOG.md +++ b/CHANGELOG.md @@ -43,7 +43,7 @@ - WDT → zone.json: map definition with full placement arrays - BLP → PNG: texture override system - DBC → JSON: data tables via DBCFile::loadJSON() -- M2 → WOM (WOM1): models with render batches, textures, materials +- M2 → WOM (WOM1/WOM2): static models + animated models with bones, keyframes, skeletal binding - WMO → WOB (WOB1): buildings with material flags/shader/blendMode, doodad rotation - Collision → WOC (WOC1): walkability mesh with slope classification, hole support, water flags - WCP (WCP1): content pack archive with categorized file list diff --git a/README.md b/README.md index a5cc7cd0..842f7891 100644 --- a/README.md +++ b/README.md @@ -47,7 +47,7 @@ cmake --build build --target wowee_editor **6 editing modes** (Sculpt, Paint, Objects, Water, NPCs, Quests) with 30+ terrain tools, multi-select, time-of-day lighting, quest chains, and full undo/redo. -**7 novel open format replacements** for all Blizzard proprietary formats: WOT/WHM (terrain), WOC (collision), WOM (models), WOB (buildings), zone.json (map def), PNG (textures), JSON (data tables).
