Super fast procedural shader for grass, flowers and debris.
Enjoyed by GPUs and cows alike!Tasty Grass Shader is the ultimate procedural framework for grass, vegetation and debris. Leveraging modern graphics techniques like Compute Shaders and Indirect Draw, it doesn't use grass prefabs and is very efficient at rendering hundreds of thousands of blades!Try the free DEMO!DOCUMENTATION & GUIDESPERFORMANCE BENCHMARKSSUPPORT & CONTACTIf you encounter any issues or have questions, we are happy to help via:Discord | GitHub | EmailFEATURES🌱 Powerful procedural generationScriptable Object-based settings systemUse any grayscale texture to control the distribution of parameters, such as: height, angle, bending, thickness, and color of grass bladesUp to four customizable layers of variationSeveral ready-to-use noise textures included.⚡ Fast and beautifulSeparated 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 systemSimple and effective procedural wind.Tweakable wind speed, strength and patterns.Use sphere colliders to make objects interact with the grass.🌿 FlexibleUse custom textures for grass blades.Create your own plants and flowers.Also usable for ground debris, like fallen leaves and pebbles.Slope cutoff control.🛫 Easy to get started14 presets for grass, flowers and debris includedSeveral grass textures included4 wind presets included⛰️ Support for Unity TerrainGrass can be assigned to entire terrain, a single Texture Layer or painted.Built-in chunk system for optimal runtime performance on large terrains.🎲 Support for any Unity MeshHeight controllable via vertex color.Vertex colors from meshes supported.Vertex colors from Polybrush supported.🕶️ Supports 3D (Forward and Deferred) and VR (Single-Pass Instanced and Multipass)🧑💻 Hack-friendlySupport for custom rendering materials.Via Unity Shader GraphVia Amplify Shader Editor.Via Shader-Code.API for loadscreens.Independent use from Unity components supported.Endpoints for custom terrain solutions included.Internal API fully exposed.REQUIREMENTSSupport for Shader-Compile Target 4.5, respectively:DirectX 11 feature level 11+OpenGL 4.3+OpenGL ES 3.1+VulkanMetal(Incompatible with WebGL)Unity 2021.3+Universal Rendering Pipeline 12.1+ or High Definition Render Pipeline 12.1+Burst 1.6+ Package (included with Unity)KNOWN ISSUESThere is no compatibility with lightmaps yet.Compatibility with Unity 6 still being evaluated.
