Major visual overhaul (Windows): - Water: analytic sky+sun reflection + refracted riverbed (Fresnel, Beer-Lambert depth tint) replacing the flat teal pane. - House: the 25 placeholder building boxes are baked into one stone-textured house.glb (makeHouse) with a wooden roof; the boxes stay as invisible physics colliders. - Procedural textures: seamless stone/wood/metal/floor + grass-blade, wildflower, and a richer seamless grass (png.ts). Props now build unconditionally since vendor tex-tech is no longer required. - Foliage: ~300 wind-swaying grass tufts + wildflowers scattered over the terrain, plus a perimeter treeline framing the arena. - Terrain: seamless grass tiling, larger tile, 512px texture. - Lighting/atmosphere: golden-hour sun, lower ambient + stronger SSAO for contrast, sky-matched aerial fog. - Player facing follows movement direction (fixes wrong-way turning). - Tooling: shot.ps1 (build+screenshot), geisterhand smoke test, preview-grass.ts texture previewer.
Completes the BRDF surface inputs — the scene shader already consumed normal maps (derivative TBN, no tangents needed) + Toksvig spec-AA, but the shooter supplied none, so every surface shaded flat with constant roughness. - png.ts: heightToNormal() derives a seamless tangent-space normal map from an albedo's luminance (Sobel height field), encoded to the engine's decode. - Terrain grass + stone/wood/floor/bark/metal now carry a derived normal map, wired via each material's normalTexture so the loader treats them as linear, mip-variance-baked normals. Surfaces now catch the directional sun with per-texel relief (masonry blocks/mortar read dimensional at grazing angles) instead of flat paint. - Verified the cached-model color pipeline is already correct (shader srgb-decodes albedo via srgb_to_linear_v), so no gamma change was needed.
…adows The ambient was crushed to 22% so the warm key sun dominated; outdoors the sky dome is a major ambient source. Measured against the house's shadowed (sky-lit) walls: 0.45 lifts shadowed surfaces with cooler sky-colour fill while keeping sun/shadow contrast (auto-exposure absorbs the overall-brightness delta, so this shifts the ambient:direct ratio, not the exposure).
…/wood/floor/bark Completes the BRDF surface inputs (albedo + normal + roughness). roughnessMR() derives a glTF MR map from albedo luminance — recessed mortar/grooves/seams read matte, faces a touch glossier; all dielectric. Wired via MR_FOR -> metallicRoughnessTexture (the shader already supports per-texel G=roughness, B=metallic gated on metal_rough.z).
Blend the planar-reflection probe (now rendering the actual mirrored trees/house, see engine) over the analytic sky dome by the probe's alpha, perturbed by the wave normal. Foliage reflections read dappled (cutout gaps show sky) which is physically correct.
A toggleable (VERIFY_CALIB) sphere grid drawn through the scene shader for objective exposure/BRDF verification: grey albedos 0.18/0.5/0.9 + a roughness sweep + a metallic sweep. Confirms the linear/AgX exposure chain (sensible grey progression, no crushed/blown tones), IBL ambient sky-fill on shadowed sides, and IBL specular reflections on the metallic row. Off by default.
… + canopy - Player facing: always orient to the camera yaw (PUBG/aim-style) instead of the movement direction while moving — strafing/backpedalling no longer points the body away from where the camera looks. - Trees: new pushTrunk() builds a tapered, root-flared, slightly-leaning, non- circular trunk (was a perfect round pole). Canopy rebuilt from overlapping leaf-card clumps + ragged outliers instead of fixed-height rings, for a rounder, less boxy silhouette.
- SUN_DIR now points TO the sun (y>0). The engine treats light/sun direction as direction-to-sun in scene diffuse (max(dot(N,light_dir),0)), shadow cascade fit (light at center+light_dir*d), and sky LUT (mu_s=sun.y). The old downward vector (y=-0.30) put the sun below the horizon → flat ambient-only ground + grazing 'weird' shadows. Removed the compensating -sun_dir negations in the water glint + analytic sky-reflection sun disc. - Player + enemy facing: updateModelAnimation takes a SINGLE rot_y angle now; the shooter still passed (sin,cos) so cos was dropped and the body rotated by sin(camYaw) rad (~stuck looking left). Player rot_y = pi/2 - camYaw (faces the camera look dir); enemies rot_y = atan2(-dz,dx) toward the player.
