[SSS] URP Super Simple Snow System

Optimized and easy to adjust to vast variation of hardware!

The [SuperSimpleSnow] system includes a ready-to-use Starter Prefab with all essential components pre-configured! Simply drag & drop SuperSimpleSnow.prefab into your URP scene and press Play!

• Adjust Material Settings for surface appearance (ground & snow textures, compressed track tint, patch scale, and view-dependent sparkles)
• Adjust SnowManager Settings in a custom Inspector for deformation, thickness, tessellation, snowfall, and object buildup
• Easy to configure & customize with a clean 5-section workflow
• Optimized GPU displacement using distance-based hardware tessellation and pooled shared materials

System includes:

• Easy Drag & Drop SuperSimpleSnow Prefab (includes a 20×20 m snow plane, surface collider, manager, snowfall particle system, and assigned materials)!
• Snowfall Particle System with adjustable emission intensity
• Interactive Snow Deformation & Persistent Tracks with customizable Interaction Layer mask, Deformation Speed, Maximum Deformation, Track Edge Softness, Track Area Radius, and Track Map Quality (up to 2048 Ultra)
• Gradual Snow Accumulation & Track Refill driven over time during active snowfall, with patchy noise-based coverage growth and adjustable track healing speed
• Dynamic Snow Buildup on Objects – grow displaced snow directly on selected opaque MeshRenderers (static or moving!) with object-space anchored textures, upward surface angle filtering, and independent thickness/tessellation controls without needing separate snow-cap meshes
• URP Snow Shader (InteractiveSnowURP) featuring tessellated thickness, exposed rock/soil slopes, compressed snow color, and view-dependent sparkle glints
• Animated Demo Scene (Demo.unity) with uneven terrain, border rocks, kinematic & physics interaction objects, and a 60-second smooth camera tour
• Procedurally generated textures (albedo, accumulation noise, sparkles, and snowflakes) and balanced default settings included
