Minecraft is a game that allows you to create whatever your heart desires, but you’re still limited by the blocks that are on offer. We’ve all been in a situation where no block looks quite right for what we want, so we have to resort to the closest approximation of the style. There is a solution to this problem, and that is texture packs.
Also known as resource packs, these completely overhaul the textures on every block in the game, as well as some of the sound design and animations. It can make Minecraft look however you want, no matter the world seed. Maybe you want a medieval look, a futuristic look, or something completely wild and imaginative. All of it is possible with texture packs.
