The resource pack for Classic Reborn 1.16.4/1.15.2 Minecraft was created solely to enhance the game's vanilla textures. Its goal is not to completely redo the look of default Minecraft, but to improve what Minecraft already offers. Everything, from blocks to items, to the GUI, is similar to default Minecraft but slightly improved. The classic game Reborn has more depth and energy, while also making it even better.
