If you have ever seen shaders for java Minecraft, then you know how realistic and beautiful the plants is waving there. I wanted to create something similar but for Minecraft Bedrock edition. I upscaled the textures to 256x256 and they still look the same as before at 16x16. And thanks to the fact that I increased the resolution of the textures, I managed to make such a smooth and beautiful animation.
There are also these options: Slow Waving Speed and Fast Waving Speed.
