Two related zone-manifest bugs:
1. displayName was always overwritten with the .adt prefix on every
export, throwing away whatever the user typed in the Zone Metadata
panel.
2. tiles vector was push_back'd to without clearing, so re-exporting the
same zone would accumulate duplicate tile entries.
Both fixed by checking displayName.empty() before assignment and calling
tiles.clear() before the rebuild loop.
Users who set a custom Map ID via the Zone Metadata panel saw it ignored
when exporting the WCP — the pack info would always say mapId=9000.
Now reads from zoneManifest_, falling back to 9000 only when the field
is unset (0).
The MODF scale field (u16 / 1024 = float) is now propagated in both
directions: load reads wp.scale -> obj.scale, syncToTerrain converts
obj.scale * 1024 -> wp.scale (clamped to u16). Combined with the prior
loader/writer changes this means non-1.0 WMO scales (used by some
WotLK content) survive a save/reload cycle.
The new persistent path->modelId map keeps models alive across rebuilds,
which is great for the common case of moving an instance, but means
models that lost all references stay in GPU memory forever. Added a
30s timer that calls m2Renderer->cleanupUnusedModels(), which has its
own 60s grace period before actual eviction — so models stick around
~60-90s after their last instance is removed and then get freed.
quickSave was the only path that cleared the flag, but exportZone is
also reachable through 'Export Open Format' and exportContentPack
without going through quickSave. Now any successful zone export clears
the dirty state so the asterisk and quit-confirm dialog reset properly.
Previously only terrain edits would trigger the 'unsaved changes' prompt
on quit, so a user who only added NPCs or quests could lose their work
by closing the window. Now checks autoSavePendingChanges_ alongside
terrain dirty state.
Camera::getForward = (cos(yaw), sin(yaw), sin(pitch)) — to make it
parallel to a direction vector we need atan2(y, x). The implementation
had x and y swapped, causing Fly To to point the camera 90deg off from
the target so the user often saw nothing.
WoweeCollision previously only contained terrain triangles; placed WMO
buildings had no collision in the exported zone, so players could walk
through walls. Added WoweeCollisionBuilder::addMesh() that transforms a
local-space mesh into world space with slope-based walkability flags,
and the editor's exportZone now walks every placed WMO and feeds each
group's geometry through it. Indoor vs outdoor groups are tagged via
the WMO group flag.
Previously just teleported camera 30u directly above the target — the user
still had to manually look down to see anything. Now positions the camera
back along the current view direction, slightly elevated, and aims it at
the selection so the target is visible immediately. Removes the round-trip
through manual rotation after every Fly To.
Marker geometry now reacts to npc.selected: 2.5x base radius (vs 1.5x),
saturated yellow with cyan tinge, and full alpha. Marker rebuild also
fires on selection change so the highlight appears immediately rather
than only after the next placement.
Auto-save was gated on terrainEditor.hasUnsavedChanges() so a session
where the user only edited NPCs or quests would lose data on crash.
Added autoSavePendingChanges_ flag flipped by every objectsDirty_ = true
site (and markObjectsDirty), cleared by quickSave. Auto-save now fires
on either dirty signal.
Placed WMO buildings reference textures (walls, floors, decorations) that
were not being exported alongside the WOB files. Added collectWMOTextures()
which loads the root WMO + all group files and gathers every texture path,
then folds these into the same PNG export pass that handles terrain and M2
textures. Exported zones now have every texture they need across all model
types.
Selected NPCs now display the move/rotate/scale gizmo and respond to
drag operations. Rotate uses only the yaw axis (NPCs have a single
orientation field, not full euler rotation). Move/scale work the same
way as objects.
Plain left-click within 4u of an existing NPC now selects that NPC rather
than dropping a new spawn on top. Shift+click forces placement at the cursor
even if it overlaps an existing NPC, preserving the rapid-placement workflow.
When an NPC with Patrol behavior is selected in NPC mode, pressing W
appends a waypoint at the current cursor position. Faster than clicking
the panel button for laying out long routes.
TextureExporter::collectUsedTextures only picked up terrain textures, so
exported zones were missing every texture referenced by NPC creature models
and placed M2 doodads. Added collectM2Textures() and unified the export
collection to include terrain + all referenced M2 paths, so the rendered
zone is fully self-contained in the PNG/WOM open formats.
Previously only placed M2 objects were converted to the WOM open format.
NPC creature models stayed as references to game M2/skin files, which
meant exported zones still depended on proprietary Blizzard assets to
render their NPCs. Now the exporter walks both placed objects and NPC
spawns and emits a WOM for every unique M2 path, making zones fully
self-contained.
Adds setPatrolPath() that draws a multi-segment orange ribbon between the
NPC's spawn position and each waypoint, plus diamond markers at each point
(green for start = NPC home, white for waypoints). Renders only while the
NPC is selected and has a patrol path defined.
Added orientation slider in NPC panel with random button. Ctrl+Wheel now
rotates the placement preview (objects and NPCs) instead of zooming —
Shift makes the step finer (5 deg vs 15 deg). Ghost preview now shows
the actual orientation that the placed NPC will have.
ROOT CAUSE of NPC models not rendering: every NPC placement triggered
an immediate full clear+rebuild of ALL M2 models. During rapid clicking,
this created a destroy-reload cycle where models were cleared faster
than they could render — the log showed rebuild firing every ~200ms
with models loading OK but being destroyed before the next frame.
Fix: debounce rebuilds with a 0.5s timer. Multiple rapid placements
reset the timer, so the rebuild only fires once after the user stops
clicking. Models stay loaded and visible between placements.
Before: click → clear all → reload all → click → clear all → reload...
After: click → click → click → (0.5s pause) → single rebuild
ROOT CAUSE of NPCs not rendering: rebuildObjects() called createInstance()
BEFORE beginFrame(), causing instance SSBO writes to use the wrong frame
index. The M2 renderer writes instance transforms to a per-frame buffer
indexed by getCurrentFrame(), but the frame index isn't valid until after
beginFrame() returns.
This is the same bug documented in the project memory:
"M2 models not rendering (draws=0): update() was called before
beginFrame(), causing frame index mismatch in instance SSBO"
Models loaded correctly (log confirmed 2192v 7926i 8b) but instances
were invisible because their transform data was written to the wrong
frame buffer.
Fix: move the rebuild block after beginFrame(), alongside update().
Many WoW instances (Dire Maul, Blackrock Depths, etc.) are WMO-only
maps with no ADT terrain tiles. The editor now handles these:
- loadWMOInstance(): reads WDT, detects WDTF_GLOBAL_WMO flag, loads
the root WMO path from MWMO chunk, places it as an object with
correct position/rotation from MODF chunk
- Automatic fallback: when loadADT fails to find tiles, tries
WMO-only loading before showing error
- Load dialog: "Find Tile" detects WMO-only instances and shows
"WMO-only instance — click Load to open" instead of "not found"
- Camera positioned near the WMO for immediate editing
- Blank terrain floor generated as ground reference
Two bugs fixed:
- Loading a new ADT tile now clears all previous objects, NPCs, quests,
path state, and terrain before loading. Was accumulating old state
across multiple loads
- ADT doodad/WMO rotation conversion now matches client's transform:
renderRotX = -adtRotZ, renderRotY = -adtRotX, renderRotZ = adtRotY+180
Was copying raw ADT rotations without coordinate system conversion,
causing models to appear at wrong orientations
When loading ADT tiles, the editor overrides terrain_.coord with the
filename-derived tile coordinates (instanced maps have arbitrary
internal values). But it wasn't recomputing the per-chunk world
positions to match, causing terrain to render at wrong coordinates.
Now recalculates all 256 chunk positions from the corrected tile
coordinates using the standard WoW formula:
chunkX = (32 - tileX) * 533.33 - cx * 33.33
chunkY = (32 - tileY) * 533.33 - cy * 33.33
This fixes terrain appearing at the wrong location in the editor
when loading instanced maps or tiles with mismatched internal coords.
One-click generation of a complete AzerothCore/TrinityCore server module
from editor zone data. File > Generate Server Module creates:
