Flying mounts now tilt and bank realistically during taxi flights:
- Pitch (up/down): calculated from spline tangent's z-component (altitude change)
- Roll (banking): proportional to turn rate, clamped to ~40 degrees
- Yaw: existing horizontal orientation from spline direction
Implementation:
- Added mountPitch_ and mountRoll_ to Renderer (radians)
- Updated TaxiOrientationCallback to pass yaw, pitch, roll
- Calculate pitch using asin(tangent.z) for altitude tilt
- Calculate roll from yaw change rate: -orientDiff * 2.5, clamped to ±0.7 rad
- Applied to mount rotation: glm::vec3(pitch, roll, yaw)
This fixes the "weirdness" where mounts flew sideways or without natural banking.
Fixes two critical taxi flight issues:
1. Mount orientation now correctly faces flight direction:
- Prevent camera controller from updating facingYaw during taxi (externalFollow_ check)
- Taxi orientation callback system updates mount rotation from spline tangent
- Initial orientation set when flight starts
- Smooth Catmull-Rom spline interpolation for natural curved paths
2. Eliminate frame hitches from tile loading during flight:
- New taxiFlightStartCallback uploads ALL precached tiles to GPU before flight begins
- Previously tiles loaded async during 3s mount delay but uploaded 1/frame during flight
- Now processAllReadyTiles() blocks briefly after mount delay to batch upload everything
- Combined with 2.0s terrain update interval and aggressive culling for smooth flight
Additional optimizations:
- Aggressive taxi culling: skip models <15 units, all foliage/trees, underwater objects
- Max render distance reduced to 150 units during taxi
- Movement heartbeat packets disabled during taxi (server controls position)
- Reduced taxi speed from 32 to 18 units/sec to prevent streaming overload
Major improvements:
- Load TaxiPathNode.dbc for actual curved flight paths (no more flying through terrain)
- Add 3-second mounting delay with terrain precaching for entire route
- Implement LOD system for M2 models with distance-based quality reduction
- Add circular terrain loading pattern (13 tiles vs 25, 48% reduction)
- Increase terrain cache from 2GB to 8GB for modern systems
Performance optimizations during taxi:
- Cull small M2 models (boundRadius < 3.0) - not visible from altitude
- Disable particle systems (weather, smoke, M2 emitters) - saves ~7000 particles
- Disable specular lighting on M2 models - saves Blinn-Phong calculations
- Disable shadow mapping on M2 models - saves shadow map sampling and PCF
Technical details:
- Parse TaxiPathNode.dbc spline waypoints for curved paths around terrain
- Build full path from node pairs using TaxiPathEdge lookup
- Precache callback triggers during mounting delay for smooth takeoff
- Circular tile loading uses Euclidean distance check (dx²+dy² <= r²)
- LOD fallback to base mesh when higher LODs unavailable
Result: Buttery smooth taxi flights with no terrain clipping or performance hitches
The client path animation completion was calling mountCallback_(0) but
not clearing currentMountDisplayId_, leaving isMounted() returning true
after landing. All three dismount paths now consistently clear the flag.
Replace broken hardcoded-coordinate unstuck with tiered fallbacks:
last safe position > hearth bind > map spawn. Track safe positions
only on real geometry, let player fall after 500ms with no ground,
and auto-trigger unstuck after 5s of continuous falling.
CMSG_TRAINER_BUY_SPELL was missing the trainerId field — server expects
guid(8) + trainerId(4) + spellId(4) = 16 bytes, not 12. Spells with
unmet prerequisites (chainNode1/2/3), insufficient level, or already
known are now greyed out with disabled Train buttons. Tooltips show
prerequisite status in green/red.
Fix SMSG_BINDPOINTUPDATE opcode from 0x1B3 to 0x155 — the old value
collided with SMSG_TRAINER_BUY_SUCCEEDED, causing buy responses to be
misinterpreted as bindpoint updates. Add specialization tabs using
SkillLineAbility.dbc to group spells by class spec (category 7).
Load BLP texture data during prepareTile() and upload to GL cache in
finalizeTile(), eliminating file I/O stalls on the main thread. Reduce
ready tiles per frame to 1. Fix camera sweep to snap Z to ramp surfaces.

updating position instead of silently ignoring
Use WMO-aware floor detection for camera clearance so tunnels don't
push the camera up to terrain. Clear permanent auras on dismount via
mount display field. Use center-only sampling for terrain/WMO floors
to prevent offset probes from snapping to terrain above tunnels.

properly. Increase WMO step height thresholds to reduce stair blocking.

TaxiNodes.dbc name was read from field 6 (Korean locale, empty) instead
of field 5 (enUS). Add BFS-based cost computation from TaxiPath.dbc
edges and display gold/silver/copper next to each destination.

skin textures, server-driven speed via SMSG_FORCE_RUN_SPEED_CHANGE, and
/dismount command. X11 XUngrabPointer on crash/hang to always release mouse.

Build now completes successfully with zero errors.
