3D Interactive Grass is a GPU-accelerated grass system for Unity..WebGPU Demo hereInteractive Grass brings your scenes to life with GPU-accelerated grass that reacts to players and objects in real time.Blades bend as characters or vehicles move through them, then spring back naturally once they pass.Grass can be cut permanently and will regrow over time all driven by a paintable terrain map you have full control over at runtime.Blade shape is fully customizable. Sculpt cross-sections, adjust taper, and tune density through an intuitive ScriptableObject workflow. No pre-built meshes, no manual placement.Best suited for: lawn mowing games, farming simulators, top-down RPGs, stealth or horror games with environmental reactivity, and any contained scene where interactive ground cover adds polish.Real-time blade bending blades react to any moving object and spring back naturallyGrass cutting and regrowth cut state is persistent and regrowth happens automatically over timeFully procedural blade geometry cross-section shape and taper are both curve-driven and fully customizablePaintable terrain map control grass density and cut state per-area, with support for pre-authored cut maps at level loadChunk-based GPU dispatching only active areas update each frame, keeping performance predictableScriptableObject workflow, all settings in one asset, easy to share and swap across scenesRuntime C# API trigger interactions, reinitialize the system, or paint cuts from your own scriptsURP and HDRP compatible (This asset is using shader graph)Tested on PC and AndroidWebGL is not supported , Works on WebGPU (Experimental) but not recomanded, Demo here.Best fit for small to medium scenes vertex count scales exponentially with blade density and terrain resolution, not suited for open world games.AI was used to generate the documentation.
