It’s understandable that playing Minecraft on Android/iOS with standard leaves and grass can get dull. You definitely need the shader called “Move (движение)”, which allows the leaves and grass to sway and move. Even if your device is not very powerful, you can still download this shader for Minecraft Pocket Edition!
