FEATURES

🌱 Powerful procedural generation

• Scriptable Object-based settings system
• Use any grayscale texture to control the distribution of parameters, such as: height, angle, bending, thickness, and color of grass blades
• Up to four customizable layers of variation
• Several ready-to-use noise textures included.

⚡ Fast and beautiful

• Separated baking and rendering pass at load time for maximum runtime performance.
• Renders hundreds of thousands of blades often under one millisecond on a modern mid-range GPU.
• Control density over distance via template settings and graphics quality settings.
• Support for Multi-Sampling Anti-Aliasing (MSAA) and Alpha-To-Coverage in URP Forward.
• See our Benchmarks here

🌬️ Wind and collision system

• Simple and effective procedural wind.
• Tweakable wind speed, strength and patterns.
• Use sphere colliders to make objects interact with the grass.

🌿 Flexible

• Use custom textures for grass blades.
• Create your own plants and flowers.
• Also usable for ground debris, like fallen leaves and pebbles.
• Slope cutoff control.
