Hot! Fullbright Texture Pack 1.12

Texture packs can’t change game logic or lighting engine. Fullbright requires modifying gamma or shader lightmaps — that’s a settings tweak or OptiFine feature, not new block textures.

Download OptiFine for 1.12.2 , then search YouTube for “Minecraft 1.12 gamma 1000” or “OptiFine Fullbright 1.12”. Or just edit options.txt yourself. It takes 10 seconds and works better than any fake “Fullbright texture pack.” fullbright texture pack 1.12
