Implementation of a GPU grass shader in Unity with fancy scripting features. See it in action here: https://twitter.com/CharlieBratches/status/1258572353174372352.
Inspired by the tech seen in Zelda: Breath of the Wild.
Features include:
- Splat mapping to control height & color.
- An additional splat map to control masking.
- Dynamic wind direction accessible through an API. Wind intensity & direction can be controlled in the scene. See the example script WindManager.
- Interactivity! If your character walks through the grass, it will bend away from their position. Supports multiple interactive objects at once.
- Automatic slope masking. (grass won't appear on very steep terrain)
- Supports your custom grass/plants/flowers/whatever textures with alpha channels (note, if you use a custom texture with a transparency channel, turn shadows off for best performance and to prevent artifacts)
- Easy to set up. Just throw the prefab in your scene and tweak away.
