WbDrawDispatcher draws all entities through WB's ObjectRenderData (VAO/VBO per GfxObj, per-batch IBO) using acdream's TextureCache for texture resolution. Two-pass rendering (opaque+ClipMap, then translucent) matching the existing InstancedMeshRenderer pattern. Per-entity single-instance drawing for N.4 simplicity — true instancing grouping deferred to N.6. Atlas-tier entities: mesh from WB, texture from TextureCache via batch SurfaceId. Per-instance-tier entities: AnimatedEntityState drives part overrides + hidden-parts, palette/surface overrides resolve through TextureCache's composite-key caches. Side-table population (Task 23 folded in): WbMeshAdapter now takes DatCollection and populates AcSurfaceMetadataTable on first IncrementRefCount per GfxObj. The side-table provides TranslucencyKind (critical for ClipMap alpha-test on vegetation) plus Luminosity, Diffuse, SurfOpacity, NeedsUvRepeat, DisableFog for sky-pass and lighting. GameWindow wiring: when WbFoundationFlag is enabled, WbDrawDispatcher draws everything and InstancedMeshRenderer is skipped. Flag-off path is unchanged. Matrix composition: restPose * animOverride * entityWorld, matching the spec. Three MatrixCompositionTests verify the contract. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
