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.
