Full opaque grass with physics and wind
Ghibli-style grass field with physics, a Wind Manager, and a display tool for meshes! Perfect for mobile games and VR. Lightweight, optimized, and ready to useFull Opaque Grass Physics & WindThe Full Opaque Grass Physics & Wind system is designed for mobile, VR, and stylized projects.It provides optimized, high-performance grass rendering effects that work seamlessly across URP, HDRP, and Built-in Render Pipeline (Forward Rendering only).This pack includes a customizable wind system, optional dynamic grass physics (trail system), a mesh placement tool, and ambient grass/firefly particle effects.Compatibility Notice:Built-in Render Pipeline: Supported with Forward Rendering only (Deferred not supported due to Shader Graph limitations).URP and HDRP: Fully supported, both in Forward and Deferred Rendering modes.--------------------------------------------------------------Features:Stylized, optimized shaders for mobile, VR, and stylized games100% Opaque Rendering for better performanceFull compatibility with URP, HDRP, and Built-in (Forward)Customizable Wind Manager includedDynamic Grass Physics (Beta version, limited to 1 interaction target for now)Multiple Shader Variations for different performance/quality needsFirefly VFX included (ambient particles)Grass Particle VFX includedDemo Scene included for quick setup and demonstration--------------------------------------------------------------Shader & Script Combinations:S_Vegetation_Interactive combined with VFX_TargetPosition_5Point script➔ Best visual quality with full grass interaction.S_Vegetation_Interactive_Simple combined with VFX_TargetPosition_2Point script➔ Optimized version for better performance on mobile and VR.S_Vegetation➔ Static grass shader with no interaction, ultra-lightweight and highly optimized.Each version is fully compatible with URP, HDRP, and Built-in Forward.--------------------------------------------------------------Copyright Notice:© Roman Chacornac 2025All rights reserved.This product is protected by copyright law and may not be distributed, modified, or resold without prior permission.Any unauthorized use is strictly prohibited.Support:If you encounter any issues or need assistance, feel free to reach out to us:Email: optifx.fr@gmail.comURP, HDRP and Built-inUnity Version: Developed and tested on Unity 2022.3.59f1, compatible with Unity 6Performance: Optimized for low-poly, mobile, and VR applicationsShader: Custom Shader, all parameters are controlled via wind manager prefab and materialDynamic Grass Physics (Beta)Three options are available:S_Vegetation_Interactive (with VFX_TargetPosition_5Point) : High-quality trail system using 5 points for smooth interaction.S_Vegetation_Interactive_Simple (with VFX_TargetPosition_2Point) : Optimized version using 2 points for lower performance cost.S_Vegetation : Lightweight version without any physics, ideal for distant grass or simpler setups.To use:1. Add the desired VFX_TargetPosition script (2Point or 5Point) to your player or moving object.2. Assign your player (or moving target) in the **Target** field in the script inspector. Limit to 1 Target.3. Apply the corresponding vegetation shader (Interactive or Simple) to your grass material.⚠️ This system is in beta. If you encounter issues, feel free to contact me.--------------------------------------------------------------Mesh Display ToolThe Mesh Display Tool allows you to manually paint grass directly on 3D mesh surfaces.How to Use:1. Select your mesh in the scene.2. Add the DisplayGrass Script3. Select the SM_Grass Prefab and adjust parameters such as density, size, and randomness.4. Generate.--------------------------------------------------------------Wind ManagerThe WindManager controls global wind direction and strength affecting all grass elements and VFX (like fireflies and floating grass).Customizable Parameters:- Wind Direction (Vector2): Controls wind direction on X and Y axes.- Wind Size (Float): Controls the size of the wind waves.- Wind Strength (Float): Determines how strongly grass is pushed.- Wind Speed (Float): Controls the speed at which wind moves.
