Two WMO rendering fixes:
1. Glass batch merging: BatchKey didn't include isWindow, so window and
non-window batches sharing the same texture got merged together. If
the window batch was processed first, the entire merged batch (lamp
base, iron frame, etc.) rendered as transparent glass. Add isWindow
to the batch key so glass/non-glass batches stay separate.
2. LOD group culling: WMO groups named with "LOD" are distance-only
impostor geometry (e.g. cathedral tower extension, hill tower). They
should only render beyond 200 units. Store raw MOGN chunk for
offset-based name lookup, detect "lod" in group names during load,
and skip LOD groups in both main and shadow passes when camera is
within range.
Extends the WMO normal mapping/POM system to character M2 models with
bone-skinned tangents. Auto-generates normal/height maps from diffuse
textures using luminance→height, Sobel→normals (same algorithm as WMO).
- Expand vertex buffer from M2Vertex (48B) to CharVertexGPU (56B) with
tangent vec4 computed via Lengyel's method in setupModelBuffers()
- Tangents are bone-transformed and Gram-Schmidt orthogonalized in the
vertex shader, output as TBN for fragment shader consumption
- Fragment shader gains POM ray marching, normal map blending, and LOD
crossfade via dFdx/dFdy (identical to WMO shader)
- Descriptor set 1 extended with binding 2 for normal/height sampler
- Settings (enable, strength, POM quality) wired from game_screen.cpp
to both WMO and character renderers via shared UI controls
POM fixes: use blurred height only for ray march (keep crisp Sobel for
normals), reduce pomScale 0.03→0.012, clamp grazing angle denominator
to 0.15, hard-limit max UV offset, smooth fadeout at steep view angles.
Add Normal Map Strength slider (0.0-2.0) in Video settings for user
control over surface detail intensity. Persisted across sessions.
Generate normal+height maps from diffuse textures at load time using
luminance-to-height and Sobel 3x3 filtering. Compute per-vertex tangents
via Lengyel's method for TBN basis construction.
Fragment shader uses screen-space UV derivatives (dFdx/dFdy) for smooth
LOD crossfade and angle-adaptive POM sample counts. Flat textures
naturally produce low height variance, causing POM to self-select off.
Settings: Normal Mapping on by default, POM off by default with
Low/Medium/High quality presets. Persisted across sessions.
Dedicated Vulkan pipeline with alpha blending AND depth writes so
windows look transparent at oblique angles without see-through artifacts.
Fresnel alpha ranges from 0.4 (grazing) to 0.95 (head-on) with sun
glint, reflections, and silver-lining specular.
- Fix MLIQ vertex stride: each vertex is 8 bytes (4 flow + 4 height), not 4
- Use MLIQ tile flags to mask out tiles with no liquid (bridges, covered areas)
- Disable wave displacement on WMO water to prevent edge slosh artifacts
- Convert screen-space depth to vertical depth for shoreline foam and water
transparency, preventing false shoreline effects on occluding geometry
- Add underwater blue fog overlay and scene fog shift (terrain water only)
- Add getNearestWaterHeightAt to avoid false underwater detection from
elevated WMO water surfaces
- Tint refracted scene toward water color to mask occlusion edge artifacts
- Lower WMO water by 1 unit to match terrain water level
- Skybox now uses DBC sky colors (skyTop/skyMiddle/skyBand1/skyBand2) instead
of hardcoded C++ color curves, with 3-band gradient and Rayleigh/Mie scattering
- Clouds receive sun direction for lit edges, self-shadowing, and silver lining
- Fixed sun quad box artifact with proper edge fade in celestial shader
- Lens flare attenuated by fog, cloud density, and weather intensity
- Replaced garish green/purple lens flare ghosts with warm natural palette
- Added zone-based weather system for single-player mode with per-zone rain/snow
configuration, probability-based activation, and smooth intensity transitions
- Server SMSG_WEATHER remains authoritative when connected to a server
Player interaction ripples: vertex shader adds radial damped-sine displacement
centered on player position, fragment shader adds matching normal perturbation
for specular highlights. Player XY packed into shadowParams.zw, ripple strength
into fogParams.w. Separate 1x render pass for water when MSAA is active to
avoid MSAA-induced darkening — water renders after main pass resolves, using
the resolved swapchain image and depth resolve target. Water 1x framebuffers
rebuilt on swapchain recreate (window resize).
- Add .setMultisample() to minimap display pipeline and recreatePipelines() for MSAA changes
- Defer all swapchain recreation in window.cpp to beginFrame() via markSwapchainDirty()
to prevent mid-frame render pass destruction crashes on resolution/fullscreen change
- Move spawnPlayerCharacter() call to after loadTestTerrain() where character renderer exists
MSAA change was called mid-frame from settings UI, destroying the render pass
and framebuffers while the command buffer was still recording. Now deferred
via pendingMsaaSamples_ flag, applied in beginFrame() before any GPU state.
Also add +180° to M2 game object orientation to fix facing direction.
Replace all glGenTextures/glTexImage2D calls in UI code with Vulkan texture
uploads via new VkContext::uploadImGuiTexture() helper. This fixes segfaults
from calling OpenGL functions without a GL context (null GLEW function pointers).
- Add uploadImGuiTexture() to VkContext with staging buffer upload pattern
- Convert game_screen, inventory_screen, spellbook_screen, talent_screen
from GLuint/GL calls to VkDescriptorSet/Vulkan uploads
- Fix loading_screen clearValueCount (was 1, needs 2 or 3 for MSAA)
Skybox: replace sphere-mesh approach with a fullscreen triangle that
reconstructs the world-space ray direction analytically via inverse
projection/view matrices. Eliminates clip.w=0 degeneracy at the horizon
and correctly maps altitude to dir.z in the Z-up coordinate system.
Clouds: hemisphere mesh was storing altitude in aPos.y (Y-up convention);
the Z-up view matrix projected this sideways, making clouds appear
vertical. Store altitude in aPos.z and update the fragment shader to
read dir.z as altitude and dir.xy as the horizontal UV plane.
- renderWorld() now calls wmoRenderer, characterRenderer, m2Renderer (+smoke,
particles) in the correct opaque→transparent order; water moved after all
opaques; per-subsystem timing active in live path
- Deleted the 310-line #if 0 GL stub block and removed #include <GL/glew.h>
(last GL reference in renderer.cpp)
- Full-screen overlay pipeline (postprocess.vert + overlay.frag, alpha blend,
no depth test/write) for underwater tint; lazily initialized, renders a blue
tint when camera is meaningfully below the water surface; canal vs open-water
tint colours preserved from original design
- overlay.frag.glsl / overlay.frag.spv added
- render sun with alpha blend while keeping moon additive glow
- add dedicated always-running sun haze timer (decoupled from moon phase cycling)
- constrain sun sprite with radial alpha mask and low-alpha discard to remove square artifact
- tune sun tint warmer without over-yellowing
- replace noisy/pulsing haze with slower flow-warp turbulence and lower amplitude
- add one-time warning caches for missing CreatureDisplayInfo and missing model path lookups
- log each missing displayId/model-path only once instead of every spawn retry/frame
- remove duplicate empty-model-path warning in spawnOnlineCreature (already reported by lookup path)
This cuts high-frequency log I/O and string formatting in hotspots when server sends unknown displayIds, while preserving first-occurrence diagnostics.
- ensure player transform sync is not gated by third-person so player shadow stays consistent
- hold shadow projection center during movement and snap once on stop to remove delayed catch-up
- smooth foliage caster transitions using blended phase-shifted UV samples
- tune foliage motion frequencies/amplitudes for less popping
- increase shadow map resolution to 2048 and retune terrain PCF texel scale

- keep shadow projection center fixed while moving to remove per-frame projection churn flicker
- replace delayed post-move catch-up with immediate stop transition and idle smoothing
- rework foliage shadow caster motion to use blended phase-shifted UV samples for continuous position transitions
- reduce high-frequency foliage threshold popping by removing threshold warping path
- sharpen terrain receive filtering with tuned 5-tap PCF weights/offset for more detailed shadows
- raise shadow map resolution to 1536 and keep light-space texel snapping for stable sampling
- set shadows enabled by default and lower global shadow strength from 0.65 to 0.62
- keep foliage animation speed consistent between moving and idle at 80%
- reduce per-tile ground clutter generation pressure and enforce tighter caps to avoid spikes
- remove expensive detail dedupe scans from the hot render path
- add progressive/lazy clutter updates around player movement to smooth frame pacing
- lower noisy runtime INFO logging to DEBUG/throttled paths
- keep terrain/game screen updates responsive while preserving existing behavior
Add page-text support for sign-like gameobject interactions by handling SMSG_GAMEOBJECT_PAGETEXT and SMSG_PAGE_TEXT_QUERY_RESPONSE, and issuing CMSG_PAGE_TEXT_QUERY when page IDs are available from cached GO template data.
Normalize received page text tokens before chat display and add a fallback for basic signpost GO type clicks to print sign names when no page data is present.
Correct M2 gameobject yaw alignment for signposts/arrows by applying render-space -90deg offset consistently across spawn, position update, and move-callback transforms; keep WMO orientation path unchanged.
Normalize WoW quest text tokens during parsing so quest titles/details no longer leak raw markup like and |n into UI. Apply to WotLK and Classic parser paths, including quest list parsing in GameHandler.
Harden quest state handling by mapping abandon requests to authoritative server quest-log slots (PLAYER_QUEST_LOG_START) instead of local vector order, with a guarded fallback when update fields are unavailable.
Improve accept de-duplication by trusting server slot state over stale local cache; allow re-accept when local/server state diverges and trigger resync semantics.
Add expansion-aware CMSG_QUESTGIVER_ACCEPT_QUEST builders: WotLK sends guid+questId+unk1(uint32), while TBC/Classic/Turtle send guid+questId only. Wire GameHandler through PacketParsers for compatibility across expansions and cores.
- resolve creature virtual item values as Item.dbc entry -> DisplayID before direct ItemDisplayInfo fallback\n- use correct WotLK virtual item base index set (starting at 56) and keep retry attach loop for late update fields\n- keep NPC main-hand weapon attachment path and clear erroneous offhand attachments\n- refactor NPC virtual weapon attach into helper with per-creature retry tracking\n- tighten humanoid facial hair geoset selection to avoid loading all beard/sideburn meshes\n- adjust facial 3xx preference to favor chin-hair channel when available
Add configurable fade-in support to MusicManager playback paths and use it for auth/login intro tracks to avoid abrupt starts. Apply a login-only 20% music attenuation while the auth screen is active, then restore the previous music volume when leaving login so in-game volume remains unchanged.
Hide NPC cloak/object-skin mesh when no cape texture resolves by using a transparent texture fallback, preventing skin-texture bleed on cloaks. Tighten NPC equipment region compositing by slot and add safe humanoid geoset selection to avoid robe-over-pants conflicts and odd pants texturing.
Reduce login/runtime hitching by deferring non-critical world-system initialization across frames, lowering per-frame transport doodad spawn budget, and demoting high-volume transport/MO_TRANSPORT diagnostics to debug. Gate M2 glow diagnostics behind WOWEE_M2_GLOW_DIAG and make zone music prewarm opt-in via WOWEE_PREWARM_ZONE_MUSIC.
- Add per-frame cap for first-time creature model loads to spread expensive model/texture decode work across frames instead of burst loading.
- Keep cached creature spawns flowing while deferring uncached display IDs, preserving world population updates with smoother frame pacing.
- Defer transport WMO doodad instancing into a queued batch processor with a strict per-frame budget to avoid multi-hundred-ms spikes when ships/elevators register.
- Process deferred transport doodad batches in both normal gameplay update and loading-screen warmup loop so heavy transport setup can be amortized before and after world entry.
- Cleanup pending transport doodad batches on gameobject despawn to prevent stale work and avoid attaching children to removed parents.
- Lower character texture cache miss logging from INFO to DEBUG to reduce log I/O contention during movement-heavy asset streaming.
- Keep WotLK chest flow stock-like by relying on GAMEOBJ_USE/REPORT_USE instead of forcing eager CMSG_LOOT.
- Preserve fallback eager-loot behavior for Classic/Turtle paths with bounded retries.
- Improve GO targeting usability by allowing gameobject pick/retarget in world click logic.
- Remove temporary loot/chest diagnostic LOG_INFO traces added during chest-open debugging.
Declare autoAttackOutOfRangeTime_ and autoAttackRangeWarnCooldown_ in GameHandler to match existing combat logic in game_handler.cpp and keep header/source state in sync.
Allow equipped bags to be moved through the shared inventory pickup/drop flow, including dragging from bag contents to bag bar and back from bag bar into bag/backpack slots.
Changes:
- Add InventoryScreen APIs to begin pickup from an equipment slot and drop held item into a target equipment slot.
- Treat inventory type 18 (bags) as valid drops on BAG1-BAG4 during slot validation.
- Route equipment placement in online mode through swapContainerItems with explicit src/dst addressing for deterministic bag slot moves.
- Update bag bar hover-drop path to use InventoryScreen drop API instead of direct local slot mutation.
- On bag bar drag start, hand off to inventory held-item drag when inventory/character UI is open so drops into bag/backpack slots work.
- keep character-selection state until world entry load/finalize completes
- move expensive post-load setup (test transport + creature callback prep) before loading screen shutdown
- add bounded world warmup pass under loading screen to drain initial network/spawn backlog
- start intro camera pan after warmup so rotation begins when gameplay becomes visible
- guard test transport setup so it runs once per session
- add per-update world socket parse budget to prevent single-frame packet-drain stalls
This reduces visible 3-4s stutter after login by shifting startup work behind the loading screen and time-slicing packet processing.
- add idempotent pending-accept tracking with timeout and per-quest cleanup hooks
- stop optimistic local quest insertion on accept; rely on server-authoritative updates
- handle QUEST_INVALID already-on/completed as reconciliation paths for pending accepts
- trigger quest metadata + status resync when accept state drifts
- add login-time quest log rebuild from PLAYER_QUEST_LOG server slots
- query quest metadata for server-slot quests to hydrate titles/objectives
- clear stale pending quest accept/query state on fresh world entry
- improve gossip quest selection fallback by trusting server quest slots when local cache is missing
This reduces duplicate accept/state mismatch loops (notably reason=13) and stabilizes WotLK quest behavior after relogs.
- Use interpolated moveInstanceTo() for normal server NPC position deltas so walk/run animations play instead of visual sliding
- Keep hard snaps only for dead units and large corrections/teleports
- Add per-creature render position cache to drive interpolation safely across frames and clear it on spawn/despawn/reset
- Keep minimap controls visible regardless of quest-status availability
- Correct minimap NPC/quest marker projection mapping to match minimap shader transform
- Add optional nearby NPC minimap dots setting (default OFF), exposed in Gameplay > Interface and persisted in settings
