- Add VK_DESCRIPTOR_POOL_CREATE_FREE_DESCRIPTOR_SET_BIT to water material
descriptor pool so individual sets can be freed when tiles are unloaded
- Free descriptor sets in destroyWaterMesh() instead of leaking them
- Add terrain manager unloadAll() during logout to properly clear stale
tiles, water surfaces, and queues between sessions
- Add diagnostic logging for water surface loading, material allocation
failures, and render skip reasons to investigate missing water
Water deduplication: merge per-chunk water surfaces into per-tile surfaces
to reduce Vulkan descriptor set usage from ~8900 to ~100-200. Uses hybrid
approach — groups with ≤4 chunks stay per-chunk (preserving shore detail),
larger groups merge into 128×128 tile-wide surfaces.
Re-add incremental tile finalization state machine (reverted in 9b90ab0)
to spread GPU uploads across frames and prevent city stuttering.
Pin main thread to CPU core 0 and exclude worker threads from core 0
to reduce scheduling jitter on the render/game loop.
- 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
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 distance-based + backface culling for STORMWIND.WMO LOD shell groups
- Hide floating cathedral shell when within 185 units of group center
- Enable backface culling for LOD shell to reduce artifacts from inside
- Increase WMO view distance from 160 to 500 units for better visibility
- Extend fog distances to 3000-4000 units for clearer long-range views
- Add fog support to water renderer matching WMO fog settings
- Add loading screen system with stb_image for JPEG loading
- Two loading screen images (orc and dwarf) randomly selected
- Display loading screen while terrain data loads
- Cache WMO inverse matrices to reduce per-frame computation
- Stub WMO liquid rendering (needs coordinate system fix)
- Update spawn point to Stormwind Trade District
