You can easily change the way your Minecraft PE world looks if you use textures and shaders. Textures only slightly change the appearance of the content, while shaders make it truly realistic. Your world gets new shades, animations, and lighting effects. Shaders can make the water look realistic, add sun shadows, and animate waving leaves. Not all devices can support large shaders, but even if your device is weak, you still can improve your MCPE world.
