- WMO window materials such as `MM_ELWYNN_WND_EXT__01.BLP` carry high `MOMT.sidnColor`/emissive values. Emissive is texture-masked and capped for window paths so it brightens the pane pattern instead of flooding the whole quad white.
- Runtime WMO cache material refresh is versioned separately from WMO geometry cache. Shader-only WMO material fixes should bump `WMO_MATERIAL_REFRESH_VERSION` instead of forcing a full `wmo_render_v1` rebake.
## 2026-07-07 M2 Billboard Pass
- Native `M2Loader` now reads `M2CompBone.flags` for billboard bits `0x8/0x10/0x20/0x40` on the static path, not only on the animated path.
- Billboard metadata is resolved per drawn vertex through the skin section bone palette and vertex bone indices. This avoids treating an entire mixed surface as billboard just because the palette contains a billboard bone.
- `M2Builder` stores billboard pivot/mode in `Mesh.ARRAY_CUSTOM0` as RGBA float data. `CUSTOM0.xyz` is the Godot-space bone pivot; `CUSTOM0.w` is the billboard mode: spherical, lock X, lock Y, or lock Z.
- `WowM2Material` applies camera-facing billboarding in the vertex shader for marked vertices. This works with grouped ADT M2 `MultiMesh` batches because the shader uses each instance transform.
- Runtime M2 cache refresh now has `M2_MATERIAL_REFRESH_VERSION`. Old cached `.tscn/.glb` meshes are replaced in memory from raw `.m2` when available, so the billboard/custom-attribute path does not require an immediate cache rebake.
- Verified with `ElwynnGrass1.m2`: native data exposes a billboard batch, the built mesh contains `CUSTOM0`, and the M2 shader compiles with the billboard uniform enabled.
- Remaining parity work: many Elwynn tree canopy M2s do not carry billboard bone flags, so their flat-looking leaves are a separate material/geometry parity issue, not this bone-billboard path.
## Practical Rule For Future Work
If something improves quality but creates visible hitch, it is not done. Move it to bake/cache/background work, split finalization over frames, or prewarm it before the player can see it.
