Lower MAX_STEP_HEIGHT from 1.0 to 0.6 so curb walls aren't skipped.
Tighten ramp and short surface filters (0.8 height threshold instead of
1.2-1.5) to prevent clipping through tunnel entrance geometry in Stormwind.
Sweep step size reduced from 1.0f back to 0.65f with max 3 steps (was 2)
to prevent clipping through ramps in Stormwind. All paths updated: follow,
free-fly, and swimming.
Shadows disabled by default in renderer, settings UI, and settings defaults.
Spawn fix: floor probe used terrain height (underground) instead of server
position when searching for spawn floor. Now probes from max(terrain, serverZ)
so WMO city surfaces above terrain are found correctly. Also invalidates
floor cache on respawn.
Delete button: moved from details panel to bottom row (small, red, far right).
Two-stage confirmation with modal popups: first asks "are you sure", second
warns "THIS CANNOT BE UNDONE" with red DELETE PERMANENTLY button.
- Skip wall collision sweep entirely when player isn't moving (saves all
collision calls when standing still)
- Reduce max sweep steps from 4 to 2 with 1.0f step size (all paths:
follow, free-fly, swimming)
- Cache floor height between frames, reuse when position changes <0.5 units
- Fix floor height not updating after walking off tall objects (fountain etc)
by always smoothing toward detected ground instead of ignoring drops >2 units
- Reduce free-fly ground probes from 5 to 1
- Disable WMO camera collision (raycast + floor probes) for performance
- Add spatial grid to raycastBoundingBoxes for when camera collision is re-enabled
Build a 2D triangle grid per WMO group at load time so getFloorHeight and
checkWallCollision only test triangles in nearby cells instead of brute-forcing
all triangles. Also reduce sweep steps (12→4), ground probes (3→1), camera
floor probes (5→2), throttle isInsideWMO to every 10 frames, and early-out
wall collision on first hit.
- Fix CMSG_BUY_ITEM count field from uint8 to uint32 (server silently dropped undersized packets)
- Character select screen: remember last selected character, two-column layout with details panel, double-click to enter world, responsive window sizing
- Fix stale character data between logins by replacing static init flag with per-character GUID tracking
- Parallelize WMO visibility culling across worker threads (same pattern as M2 renderer)
- Optimize WMO collision queries with world-space group bounds early rejection in getFloorHeight, checkWallCollision, isInsideWMO, and raycastBoundingBoxes
- Reduce camera ground samples from 5 to 3 movement-aligned probes
- Add WMO interior lighting, unlit materials, vertex color multiply, and alpha blending support
Split the M2 animation update loop into three phases: sequential animation state update, parallel bone matrix computation via std::async (when 32+ animated instances), and sequential particle update. Each thread processes a disjoint slice of instances so no synchronization is needed.
Extract skill data from PLAYER_SKILL_INFO_1_1 update fields (636-1019), detect
skill increases with chat messages, and replace placeholder Skills tab with live
data grouped by category with progress bars.

Build now completes successfully with zero errors.

CMSG_BUY_ITEM was missing the trailing uint8 bag field, causing the
server to silently drop undersized packets. Add handlers for
SMSG_QUESTGIVER_REQUEST_ITEMS and SMSG_QUESTGIVER_OFFER_REWARD with
UI windows for quest completion and reward selection.
Only SkillLine category 7 (Class) gets its own tab, giving the 3 spec tabs
(e.g. Discipline/Holy/Shadow for Priest). Weapon skills, racials, professions,
and utility spells all go into the General tab.
- Rewrite SpellCastResult enum to match AzerothCore 3.3.5a values (was misaligned, showing wrong error messages like "Not while trading" instead of "Unit not in front")

- Fix player frame showing wrong character name by looking up activeCharacterGuid instead of always using characters[0]
- Clear playerNameCache on disconnect to prevent stale names across sessions
The particle emitter parser had three bugs causing OOM crashes during loading:
- Struct size was 496 bytes instead of correct WotLK 476 (0x1DC), misaligning multi-emitter models
- FBlocks were read as 20-byte M2TrackDisk instead of 16-byte FBlockDisk (no interp/seq prefix)
- parseAnimTrack had no cap on sequence count, allowing garbage data to allocate billions of entries
Left-click on action bar slots now casts spells/uses items instead of starting a drag. Right-click-drag rearranges slots. Spells can be dragged from the spellbook directly onto the action bar, replacing the old "Assign to" button row.
After accepting a quest, re-query the NPC so its marker updates from ! to ?. After completing a quest, re-query all nearby quest NPCs so markers refresh. Also remove completed quests from the log instead of just marking them.
