Shadow casting: foliage batches now bind their actual texture in the shadow
pass with alpha testing, producing leaf-shaped shadows instead of solid cards.
Uses a per-frame resettable descriptor pool for texture sets.
Shadow receiving: foliage fragments now sample the shadow map with PCF
instead of using a flat constant darkening.
Gameobject M2 instances (books, crates, chests) were continuously
cycling their animations because M2Renderer unconditionally loops
all sequences. Added setInstanceAnimationFrozen() and freeze all
gameobject instances at creation time so they stay in their bind pose.
removeInstance() and removeInstances() were erasing M2Instances without
calling destroyInstanceBones(), leaking VMA bone buffers permanently.
This caused framerate to drop and never recover after NPC encounters.
All three shadow renderers (WMO, M2, Character) were iterating every
loaded instance with zero culling. Now skip instances outside the
180-unit shadow frustum radius via squared-distance check.
Raise all texture cache defaults from 1GB to 4GB to reduce rejections.
Cap cache-full warnings (texture + model) to 3 messages per renderer,
and cap update block parse errors to 5 messages.
Strip per-frame/periodic logging from CharacterRenderer (batch dump,
instance count) and M2Renderer (frame timing profiler) to avoid
unnecessary string formatting and I/O in render loops.

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.
Replace 2D screen-space ding rings with real WoW LevelUp.m2 particle/geometry
effect. Fix FBlock particle color parsing (C3Vector floats, not CImVector bytes)
which was producing blue/red instead of golden yellow. Spell effect models bypass
particle dampeners, glow sprite conversion, Mod→Additive blend override, and all
collision (floor/wall/camera) to prevent camera zoom-in. Other players' level-ups
trigger the 3D effect at their position with group chat notification. F7 hotkey
for testing.
Mod blend (GL_DST_COLOR, GL_ZERO) multiplies the framebuffer by texture color,
so dark pixels create visible black rectangles. Use a variable colorKeyThreshold
uniform (0.7 for Mod/Mod2x, 0.08 default) to discard dark pixels from these
batches while preserving normal colorKeyBlack behavior elsewhere.
The pixel content glow detection (>60% dark = glow) was too aggressive,
flagging dark metal textures on sconces as glow textures and making
structural geometry transparent. The forced additive blending for
colorKeyBlack batches compounded the issue.
Reverted both. Added per-batch diagnostic logging for models containing
"light", "lamp", or "lantern" to identify the actual blend modes and
material flags on Stormwind bridge lamps.
force additive blending for colorKeyBlack batches
Two key changes:
1. Detect glow-like textures by analyzing pixel content during loading:
textures that are >60% near-black with some bright pixels are flagged
as colorKeyBlack regardless of filename. This catches glow textures
like Stormwind street lamps whose paths don't contain keywords like
"lamp" or "lantern".
2. Force additive blending (mode 3) for batches with colorKeyBlack
textures that have blendMode 1 or 2. These textures are designed for
additive blending where black = transparent, but some M2 files specify
Alpha or AlphaKey blend modes which cause black areas to render as
solid dark disks instead of being invisible.
Two fixes:
1. shouldUseGlowSprite now requires the UNLIT material flag (0x01) for
the colorKeyBlack+flameLikeModel path. Previously, structural geometry
(torch handles, sconce brackets) on flame-like models got replaced
with glow sprites because their texture paths contained keywords like
"torch" in the directory name, setting colorKeyBlack on non-glow
textures. Requiring UNLIT ensures only actual glow/emissive batches
become sprites while lit structural geometry renders normally.
2. Fragment shader now discards near-black (maxRGB < 0.1) for ALL unlit
non-opaque batches, not just additive blend modes. Glow effects on
lanterns/lamps that use blendMode 1 (AlphaKey) or 2 (Alpha) instead
of 3 (Additive) now properly discard their black backgrounds.
Three-part fix for glow textures showing opaque black rectangles instead
of being transparent:
1. Pass blend mode to fragment shader via uBlendMode uniform. For additive
blend modes (3=Add, 6=BlendAdd), discard near-black fragments (maxRGB
< 0.1) since they contribute nothing visually but render as dark
rectangles against sky/terrain.
2. Expand colorKeyBlack texture keyword detection to include "lamp",
"lantern", "glow", "flare", "brazier", "campfire", "bonfire" in
addition to the existing "candle", "flame", "fire", "torch".
3. Expand flameLikeModel detection for glow sprite conversion to include
"brazier", "campfire", "bonfire". Also compute glow centers for
colorKeyBlack batches (not just blendMode >= 3) so glow sprites
position correctly for all flame-like objects.
Both passes were rendering the entire loaded scene (17×17 tile radius)
into a shadow map that only covers 360×360 world units — submitting
10-50× more geometry than the shadow frustum can actually use.
- TerrainRenderer::renderShadow: skip chunks whose bounding sphere
doesn't overlap the shadow frustum AABB in XY. Reduces terrain draw
calls from O(all loaded chunks) to O(chunks within ~180 units).
- M2Renderer::renderShadow: skip instances whose world AABB doesn't
overlap the shadow frustum in XY. Reduces M2 draw calls similarly.
- Both functions now take shadowCenter + halfExtent parameters.
- SHADOW_MAP_SIZE 2048→1024: 4x fewer pixels rasterized in depth pass
- Replace 9-tap manual PCF loop with single hardware PCF tap in all 4 receiver
shaders (terrain.frag, wmo_renderer, m2_renderer, character_renderer).
GL_LINEAR + GL_COMPARE_REF_TO_TEXTURE already gives 2×2 bilinear PCF per
tap for free, so quality is maintained while doing 9x fewer texture fetches.
- Throttle shadow depth pass to every 2 frames; OpenGL depth texture persists
between frames so receivers always have a valid shadow map. 1-frame lag at
60 fps is invisible.
Batches whose named texture fails to load now render invisible instead of
white (the swampreeds01a.blp case causing a white shell around aquatic plants).
Also implements proper M2 opacity plumbing:
- Parse texture weight tracks (M2Track<fixed16>) and color animation alpha
tracks (M2Color.alpha) to resolve per-batch opacity at load time
- Skip batches with batchOpacity < 0.01 in the render loop
- Apply M2Texture.flags (bit0=WrapS, bit1=WrapT) to GL sampler wrap mode
- Upload both UV sets (texCoords[0] and texCoords[1]) and select via
textureUnit uniform, so batches referencing UV set 1 render correctly
M2 models like OrgrimmarFloatingEmbers and OrgrimmarSmokeEmitter have a
simple box mesh (24 verts, 36 indices) meant only to define particle
emitter bounds. Their blendMode was 0 (opaque), causing them to render
as large grey boxes. Detect these by checking for box geometry with
particle emitters and large bounds (>5 units), then mark as invisible.
Also add ANTIPORTAL and batch-disable flag checks to WMO group filtering.
- Fix FBlock color keys from 3-byte BGR to 4-byte RGBA (CImVector) to
prevent garbled purple/red colors from byte misalignment
- Add circular soft-edge falloff in particle fragment shader (GL_POINTS
rendered as squares by default)
- Apply default gravity (4.0 spray, 1.5 mist) when M2 gravity is 0 since
bone animation from .anim files isn't loaded yet
- Add drift velocity to speed=0 emitters so particles spread as mist
instead of clustering at static bone positions
- Run particle updates for all nearby instances, not just those in
boneWorkIndices_, to prevent particles freezing when bone culled
- Wrap animation time for particle models to keep emission tracks looping
- Cap particle scale to 1.5 and reduce point size multiplier (800→400)
- Desaturate FBlock colors 70% toward white for natural water appearance
- Reduce additive blend alpha to 5% and volume particles to 2%
- Per-family mount sounds (kodo, tallstrider, mechanostrider, etc.) detected from M2 model path
- Skip WMO groups with SHOW_SKYBOX flag or all-untextured batches (grey mesh in Orgrimmar)
- Freeze physics during taxi landing until terrain loads to prevent falling through void
- Disable bone animations on tropical vegetation (palm, bamboo, banana, etc.) to fix wiggling
- Snap player to final taxi waypoint on flight completion
- Extract mount aura spell ID from classic UNIT_FIELD_AURAS for CMSG_CANCEL_AURA dismount
- Increase /unstuck forward nudge to 5 units
