Dynamic Grass Shader System (Shader Graph Based)This asset is a fully Shader Graph–based dynamic grass shader system, designed with a strong focus on customization, visual fidelity, and performance. All visual and behavioral aspects of the grass are controlled directly through the shader, allowing artists and developers to achieve a wide range of styles, from stylized to semi-realistic, without additional scripts or textures.🎨 Advanced Color & Surface ControlThe shader offers extensive color customization, including:Grass Color and Flower Color blending with terrain colorHue shifting and random value variation to break repetitionAdjustable specular and smoothness for different lighting scenariosNormal map support with controllable strengthGround-based Ambient Occlusion for natural surface blendingThese features ensure that large terrains remain visually rich and organic, even at scale.🌿 Subsurface Scattering (SSS)Built-in Subsurface Scattering simulates realistic light transmission through grass blades, creating soft and natural lighting—especially effective during sunrise and sunset scenes.HDR color support, combined with adjustable SSS strength, angle, and texture influence, makes the shader suitable for both realistic and stylized projects.🍃 Vertex-Based Wind AnimationThe shader includes a powerful vertex animation system that simulates natural grass movement:Wind noise, speed, strength, and direction controlDirectional influence and randomization for organic motionSmooth large-scale bending driven entirely on the GPUThis ensures believable wind behavior across vast environments without performance-heavy simulations.🚶➡️ Player InteractionGrass dynamically reacts to player movement:Distance-based bending and alignmentSmooth deformation and recoveryAdjustable interaction radius and strengthThis creates immersive, responsive environments where grass feels physically present in the world.🚀 Performance OptimizedFor large open environments, advanced optimization techniques such as GPU Instancing, Animation Culling, Occlusion Culling, and Terrain Distance–based optimization are used. All flowers are packed into a single texture, and all grass uses one shader and a single material.There is no code, no graphics API dependency, no additional components, and no unnecessary complexity.Despite having a very high grass density, the demo scene processes all grass in only 2–3 milliseconds. The system is designed to be extremely simple, clean, and efficient.✅ Key Features100% Shader Graph based (no scripts required)Highly customizable color, lighting, and animationSubsurface Scattering with HDR supportWind-driven vertex animationPlayer interaction supportOptimizationSupport for URP & HDRPPerfect for open-world games, stylized environments, and realistic outdoor scenes.INCLUDED:34x Model(Group mesh, Single mesh)34x Prefab1x Shader1x Material1x Editor Script(Bake Terrain Color)3x Sound(+1 Sound Controller Scirpt)1x Demo SceneTerrain Data, Terrain Textures, Terrain Layers for Demo SceneDocumentationNote: It has been tested on Unity 2022 and Unity 6 versions.
