+# SHADER-134 — PBR procédural optionnel et herbe SSGI
+
+Demande : ajouter en option des normales calculées à partir des textures actives,
+avec rugosité des matériaux et reflets orientés. Retour : le SSGI renforcé
+éclaire artificiellement l'intérieur de l'herbe ; vérifier et corriger ce cas.
+Branche `codex/pbr-beta134`, socle beta.133, Minecraft 26.3 / Java 25.
+
+## Contrat
+
+PBR initialement OFF, intensité 50 réglable 0–100. Cartes de normales à partir
+des différences de luminance, amplitude limitée ; rugosité/métallicité par
+famille de blocs, repli rugueux pour les types inconnus. Analyse des ressources
+actives conservée en cache jusqu'à désactivation ou rechargement ; pas de fichiers
+écrits dans le pack personnel, pas de GPU readback en production.
+
+Portée 32 blocs, sections visibles construites progressivement. Budget de maillage
+24 Mio, atlas de 4 096 matériaux en 16 × 16 avec bordures (1 280 × 1 280 RGBA8,
+6,25 Mio), copie RGBA8 de l'image courante et uniformes. Les textures de plus haute
+résolution sont échantillonnées à 16 × 16 ; première image des textures animées.
+La couleur et l'animation restent celles de l'atlas natif. Pas de parallax ni
+de géométrie ajoutée aux blocs ; les motifs clairs peuvent donner un faux relief.
+
+La passe utilise une réponse spéculaire GGX (normales, rugosité, métallicité,
+Fresnel) et module l'éclairage diffus déjà rendu. Elle ne remplace pas tout le
+pipeline Minecraft par un moteur PBR physique. Soleil/lune, exposition au ciel et
+carte d'ombres active limitent les reflets ; pas de reflets miroir, d'environnement
+SSR, ni de direction locale déduite pour chaque torche. Aucun rendu PBR d'eau,
+d'entités, d'items ou de modèles spéciaux hors maillage de terrain.
+
+## SSGI
+
+Les normales des faces presque axiales sont stabilisées sur leur axe. Deux passes
+spatiales filtrent la lumière indirecte à demi-résolution, avec rejet des voisins
+hors du plan du récepteur et interpolation de l'échantillonnage. Les textures de
+l'image restent nettes. Un tampon RGBA16F supplémentaire à demi-résolution porte
+le budget des cibles SSGI à environ 8 octets par pixel plein écran (contre 6).
+Pas d'historique temporel ni de rémanence ajoutés.
+
+Un parcours de 12 blocs a reproduit des bandes sur un mur et un éclaircissement
+artificiel d'herbe à 35 et 100. Le filtrage seul ne suffisait pas : la collecte
+réinjectait aussi trop fortement la lumière ambiante neutre. Elle conserve
+maintenant la composante chromatique de la source, en soustrayant son canal
+linéaire minimum. L'éclairage ambiant neutre reste celui de Minecraft. Ce réglage
+vise le transfert de couleur voulu, pas une simulation physique complète du
+rebond blanc. Les sources hors champ/cachées restent absentes du SSGI ; le résultat
+peut encore varier lors d'un déplacement important. PBR et SSGI restent indépendants.
+
+## Vérification
+
+Test PBR ciblé réussi en 1 min 13 s : relief éclairé/ombré, intensités 20/50/100,
+soleil matin/soir, cache stable, préférences, OFF/zéro, mouvement infinitésimal,
+redimensionnement, rechargement et combinaison des effets. Le premier parcours
+SSGI est conservé comme reproduction ; résultats finaux ci-dessous.
+
+
+Le parcours corrigé a réussi en **2 min 47 s** avec 13 positions réparties sur
+12 blocs, à 35 et 100, chaque fois comparées à OFF. Un mob immobile, des brins
+d'herbe et un mur figurent dans la scène. Retour au point initial sans rémanence.
+Sur les captures de ce parcours, le maximum du gain vert moyen mesuré dans
+l'herbe passe sous 9,73 niveaux à 35 et 24,51 à 100. Le test impose ensuite
+respectivement des limites de 12 et 30 à chaque position. L'essai reproduisant
+le défaut atteignait notamment 23,68 et 49,20 à l'extrémité droite.
+Ces mesures décrivent cette scène, pas une garantie d'absence d'artefacts
+dans tous les mondes ni sur toutes les cartes graphiques.
+
+
+La suite client complète réussit en **7 min** sur macOS / Apple M1 / OpenGL.
+Elle inclut le parcours latéral et ses seuils de gain, les deux couleurs de rebond,
+le PBR, les ombres, le feuillage, les cinq précisions, le CTM, les émissifs, le
+bloom, les préférences et les écrans FR/EN. Log : `build/shader134-client-full.log`.
+Le contrôle PBR final réussit en **1 min 19 s** : placement/retrait d'un toit,
+invalidations de lumière/maillage et rendu combiné avec les ombres actives. Les
+reflets utilisent maintenant la grille des ombres pour leur test de visibilité. Aucun résultat Windows/Vulkan ni
+mesure de FPS revendiqués.
+
+
+## Construction et artefacts
+
+`./gradlew check build assemblePack assembleTestPack -x :sanctuary:runGameTest`
+réussit en **2 min 22 s**, 126 tâches. Le serveur GameTest dédié reste exclu
+conformément au refus EULA antérieur. Log : `build/shader134-build.log`.

+aux sources. Comparaison à beta.133 : **23 entrées de production** changées,
+limitées au rendu, à ses options et points d'appel. Gameplay et gemmes inchangés.
