Nature X is a texture pack that has the capability to make Minecraft look like a completely different world. The pack focuses on adding much more clarity to the game. The textures are crisp and clear. Forest biomes will haven trees that are of different colour from vanilla. These are mostly noticeable on birch trees, whose leaves are now pink. Also, all of the leaves are given a bushy textures. They have 3D elements on them, that gives them depth and makes them look rounded. The grass in the forest biomes also have variations, which adds to the detail. Optifine is required to make this pack function properly. Turning on a shader with this pack will turn your game into a truly different experience.
