## v1.5 ### Materials alpha * Added a shared lightweight material library with LabPBR 1.3 normal, AO, perceptual smoothness, F0/metal, and emissive decoding; absent maps retain a neutral matte fallback * Added Natural and Pronounced built-in material styles; the stronger choice only changes generated vanilla metal/polished smoothness and never alters LabPBR resource-pack data * Terrain, entities, and the hand/held-item pass now use tangent-space normals and an inexpensive GGX/Smith/Schlick direct response without replacing the existing lighting model * Extended the material path to translucent water and glass: genuine resource-pack normal detail can perturb procedural water without flattening absent-map waves, while glass reads LabPBR normal, AO, F0, smoothness, and emission channels * Added conservative built-in metal and polished-mineral classes for vanilla textures; ordinary stone, wood, soil, and foliage deliberately remain matte * Reused `colortex3` for opaque material normals/reflection strength, with separate class ranges for opaque materials, portals, puddles, and water * Added Off / Sky Only / SSR material reflection tiers and profile defaults: Low compiles materials out, Medium uses sky reflections, and High/Ultra permit material SSR * Added a dedicated Materials options page with Built-in / LabPBR Resource Pack source and specular-strength controls ### Distant Horizons * Added dedicated compatibility-profile `dh_terrain`, `dh_water`, and future-ready `dh_shadow` programs for the Overworld, Nether, and End * DH terrain reuses Solstice's sky light, block light, weather color, cloud shadows, foliage response, emissive classification, and dimension lighting * Added distance-filtered world-space material detail for grass/leaves, stone, deepslate, wood, dirt, sand, snow, terracotta, Nether stone, metal, and lava; this restores surface breakup where Iris cannot expose block-atlas UVs to the DH shader path * Corrected DH grass blocks being treated as translucent foliage and metal being treated as emissive; metal now receives a restrained broad highlight instead * DH water uses biome color, Solstice's user water tint, distance-stable waves, physical Fresnel, sky reflections, light glints, and transparent blending * Native and DH depth now share one scene-classification/reconstruction helper * Atmospheric fog preserves the native look near the player, thins beyond the native horizon for readable vistas, and dissolves only at the outer DH render edge * Clear-weather DH atmosphere was opened further so distant landforms retain colour and contrast; rain, thunder, dawn mist, and dimension atmosphere remain denser * Added a defensive Overworld cave-face rejection for fully enclosed DH geometry below sea level, preventing stale cave LODs from leaking through the native/DH handoff * Very distant DH color now receives restrained aerial chroma/contrast compression, reducing fluorescent repeated color across large LOD triangles * Clouds and half-resolution reconstruction no longer mistake LOD silhouettes for sky * Light-shaft occlusion, underwater absorption, and native-water SSR now see DH geometry * Sun glare now uses a soft 16-point visibility probe plus angular broad/core response, so terrain occlusion and crossing the player's FOV edge fade continuously instead of switching the effect off * SSAO, puddle metadata, and material-style surface effects remain native-only, avoiding wasted work and false seams on low-detail LOD meshes * DH shadows are deliberately disabled until their all-LOD pass meets the performance budget; the depth-only program is present for future profiling * Base rendering remains guarded by Iris's `DISTANT_HORIZONS` feature macro, preserving the existing non-DH path ### Weather and color * Volumetric cloud bodies now combine vertically decorrelated erosion fields with flatter bases, taller coverage-driven tops, and billowed internal density instead of extruding one 2D weather shape through the entire layer * Reduced first-hit cloud extinction so the march reveals multiple illuminated density layers; High and Ultra add a second long-range sunlight probe, while clear-sky bounce and an inexpensive multiple-scattering floor keep shadowed daytime lobes blue-white rather than charcoal without brightening storm clouds * Underwater sky rays now use solid depth behind the water surface to generate and merge the same cloud layer seen above water; water extinction and the Snell window attenuate that layer afterwards, so submerged views can no longer reveal a cloud-covered moon * The shared sun/moon visibility probe now multiplies terrain visibility by resolved cloud transmittance, keeping celestial discs, halos, glare, and light shafts consistent * Rebuilt shooting stars as sub-second meteors with a compact warm head, narrow tapered blue-white plasma trail, breakup flicker, and one shared life envelope; the old multi-second moving glow segment and lingering-looking smear are gone * Stars, meteors, moonlight, and the lunar halo now use the smoothed weather state, preventing celestial clarity from snapping ahead of cloud recovery after rain * Rain atmosphere now uses an Iris-smoothed weather state: storms close visibility quickly, while fog, cloud cover, lighting, reflections, and sun glare recover gradually for twelve seconds after rain instead of revealing the full DH landscape at once * Rain/DH fog is substantially denser at long range, matching the short visibility expected from humid heavy weather while preserving nearby silhouettes * Added Natural and Vivid color grades alongside the legacy Classic response; Natural is the new default and tone-maps luminance rather than RGB channels independently, preserving hue through highlights * Natural grading applies restrained highlight/shadow chroma compression, gamut compression, and weather-aware white balance; default saturation is now neutral rather than boosted * Cloud macro shaping no longer suppresses an enormous low-frequency region around the camera column, removing the persistent clear crater seen when looking straight upward * DH water now rejects pixels covered by native opaque depth and fades in across the native water range, preventing ocean bands from drawing across portals, terrain, and builds * Top-down DH water now matches native water's 2% normal-incidence Fresnel, body tint, and transparency instead of becoming a bright, highly reflective sheet * Underwater extinction now follows the Water Murkiness setting for native and DH geometry; suspended-particle haze closes long-distance visibility, and the water surface softly limits the above-water scene to a physical Snell window instead of exposing the entire world * The defensive DH cave filter now rejects fully enclosed zero-skylight Overworld LOD faces at any elevation, covering modded caves and incomplete world-generation columns * Sunrise atmospheric color is now confined around the sun instead of reflecting as a straight neon horizon band; twilight cloud bodies stay neutral while their lit edges warm ### Capture-driven performance * Used an AMD RenderDoc counter capture to identify the full-resolution effect merge, volumetric clouds, final output, atmosphere/water, and AO mask as the meaningful Solstice post costs; the already inexpensive bloom and portal-blur passes were left unchanged * Reworked cloud reconstruction to use its existing alpha coverage instead of rereading native and DH depth for every neighbouring half-resolution texel * The final effect merge now builds half-resolution coordinates once and shares native depth samples between surface effects and light shafts, while underwater shafts continue using the solid depth hierarchy * The merge reads the existing 1×1 celestial visibility result and skips all shaft-buffer reconstruction when the light source is off-screen, fully occluded, or otherwise inactive * FXAA reuses the final pass's existing centre colour instead of sampling it twice at full resolution * Volumetric cloud rays now hoist weather and lighting constants out of the density loop; primary density remains evaluated at every step while the smoother solar-occlusion probe is reused for one adjacent occupied step through the existing temporal reconstruction * The terrain path now reuses its vertex distance and per-fragment direct-light colour, removing repeated length, celestial normalization, and weather-light calculations from the indexed chunk draws highlighted by the capture ### Gameplay polish * Added Survival, Balanced, and Builder lighting styles as a visual preference independent of Low/Medium/High/Ultra; the modes adjust night illumination, sky-light response, block light falloff, held light, and interior indirect floors without changing daytime exposure * Renamed Night Darkness to Night Brightness so the slider direction is unambiguous * Added optional low-strength contrast-adaptive sharpening after FXAA, with neighborhood clamping and flat-region rejection to restore texture clarity without strong sky noise or edge halos; underwater sharpening is skipped ### Render paths and Minecraft 26.2 * Added explicit lightweight programs for damaged blocks, block entities, translucent block entities, beacons, items, particles, translucent particles, translucent entities, lightning/dragon beams, armor glint, emissive eyes, and translucent held objects in the Overworld, Nether, and End; lines deliberately use Iris's documented `gbuffers_line` to `gbuffers_basic` fallback * Translucent entity and block-entity passes retain forward lighting but no longer write opaque material/SSR records into `colortex3` * Added `item.properties` and separate main/off-hand light evaluation, allowing warm, soul-blue, redstone-red, amethyst/end-purple, and plant-orange held-light colors * Replaced hardcoded cutout thresholds with Iris's `alphaTestRef` in terrain, entity, hand, generic textured, lit textured, shadow, and special overlay paths * Enabled Iris's separated translucent entity/block-entity draws and mixed particle ordering; beacon beams remain non-depth-writing so they cannot carve holes through fog * Expanded current content metadata for Spring to Life foliage, golden dandelions, pale-garden plants and lights, trial spawners/vaults, copper bulbs, current emissive mobs, and the Minecraft 26.2 sulfur/cinnabar building families
