High-performance mobile grass system for Unity URP. 100,000 blades at 60 FPS on real mobile hardware. Tested on iPhone SE and Samsung A54.Requires the Universal Render Pipeline (URP) package. If URP isnot detected on import, GrassLite's shaders remain safelyinactive (no compile errors) and a dialog guides you to installURP via Package Manager — shaders then activate automatically.[BT] PERSIA VFX — Grass LiteHigh-Performance Mobile Grass System for Unity URP** Requires the Universal Render Pipeline (URP) package. **100,000 grass blades. 60 FPS. Real mobile hardware.Not a benchmark. Actual footage recorded oniPhone SE and Samsung A54.GrassLite is a complete, production-ready grass system builtfor mobile first — then scales up for PC and console.No Compute Shader. No GPU Instancing tricks. Pure baked meshthat runs on any device supporting URP.WHY GRASSLITE?Most grass assets are built for PC and ported down to mobile.GrassLite is the opposite — built from the ground up formobile performance, then scaled up for beauty.The result: a system that actually ships.FEATURESPERFORMANCE- 100k blades at 60 FPS on iPhone SE (A15) and Samsung A54- Baked mesh — zero runtime CPU cost after build- 3 performance presets: Mobile Fast / Balanced / Beauty- LOD system with 3 levels + frustum culling (optional, secondary feature - still being refined for stability; improvements planned in upcoming updates)PLACEMENT- Works on any URP mesh — no Unity Terrain required- Source mesh must have UV coordinates (UV0)- Paint mask — paint exactly where grass grows in Scene View- UV Mode: Mesh UV or World XZ World XZ recommended for low-poly terrain with distorted UV- Exclusion Zones — keep grass away from trees, rocks, buildings Supports Circle, Box, and Mesh-based shapesVISUALS- Custom URP shader with mobile shadow support- Root darkness, tip brightness, cross-blade support- Natural and Stylized blade shape presets- Wind modes: Breeze, Storm, Custom- Point light supportINTERACTION- Real-time grass bending — objects push and flatten blades- Up to 8 simultaneous interactors (player, NPC, vehicle)- Tune Strength, Push, and Flatten independentlyWORKFLOW- One-click Quick Setup from Inspector- Rebuild grass in seconds- Force Up Direction — correct placement on low-poly terrain- Interactive Demo Scene with live runtime controls- Compatible with Unity 2022.3 LTS and newerPERFORMANCE PRESETSMobile Fast ~8,000 blades Low-end mobile, older devicesBalanced ~25,000 blades Mid-range mobile (recommended)Beauty ~50,000 blades High-end mobile and PCMESH REQUIREMENTSSource mesh must have UV coordinates (UV0).Standard terrain and low-poly terrain with UV are supported.Mesh with no UV at all is not supported — unwrap first.WHAT'S INCLUDED- Grass System — core runtime + full editor toolset- Custom URP Grass Shader- Terrain Diffuse Shader (mobile shadow-only)- Interactive Demo Scene with runtime control panel- Sample terrain mesh (40×40)- Default grass texture and paint mask- Full documentation and quick start guideREQUIREMENTS- Unity 2022.3 LTS or newer- Universal Render Pipeline (URP)- Source mesh with UV coordinates (UV0)[BT] PERSIA VFXBuilt for developers who ship on mobile.- Unity 2022.3 LTS or newer- Universal Render Pipeline (URP) required- Source mesh with UV coordinates (UV0) required- Baked mesh — zero runtime CPU cost after build- Up to 8 simultaneous grass interactors- LOD system with 3 levels + frustum culling (optional, in refinement)- Tested: 60+ FPS on iPhone SE and Samsung A54AI tools (Claude, ChatGPT, and Gemini) were used to assist inwriting C# scripts, editor tooling logic, and documentation, aswell as generating UI textures and brand/logo assets.All AI-assisted output was manually reviewed and modified by thedeveloper to ensure it functioned correctly within the project —including debugging and adapting code to match the actual projectstructure, verifying behavior directly in the Unity Editor, andrefining visual assets for consistency with the final brandidentity.All in-app screenshots, demo footage, and gameplay videos areunedited captures from the Unity Editor and real Android/iOSdevices, with no AI generation or alteration.
