A camera-following ambient particle system with pollen, dust and ash, organic mote trails, directional wind and independent layer controls.🍃 Ambient Particles Essentials — 3 Organic Atmosphere StylesAmbient Particles Essentials is a free ambient particle system for bringing subtle life to your Unity scenes with floating pollen, warm dust and drifting ash.The atmosphere follows your camera while particles remain in world space, keeping the effect around the viewer without filling your entire level with particles.3 Atmosphere Styles:🌿 Pollen & Spores · ✨ Floating Dust · 🔥 Ambient AshEach style has its own colours, motion, layered detail and luminous mote trails.🧩 One-Script Integration:Add AmbientBiomeParticles to a GameObject, assign your camera or use the automatic MainCamera fallback, and press Play.The component starts with the included Pollen profile when added through the Inspector.A ready-to-use prefab is also included.🚫 No manual Particle System setup🚫 No Shader Graph or third-party plugins required🌍 Camera-Following Atmosphere:A local emission volume follows the observer, with forward-biased coverage and surrounding detail.Particles drift naturally in world space instead of moving rigidly with the camera.✨ Organic Mote Trails:Moving particles leave independent, softly glowing motes along their paths.Golden dust · Luminous pollen clouds · Cooling ember sparksSmooth drift, spread and fading give each style its own character.🌬️ Directional Wind:Adjust wind direction in degrees and control its strength at runtime.Natural particle motion continues alongside the wind, avoiding a rigid, uniform flow.Optional wind wisps visualize its direction. Bind a directional Unity WindZone or drive wind through the scripting API.🎛️ Independent Layers & Runtime Tuning:Four optional layers per style, all enabled by default:Fine particles · Round detail motes · Soft halos · Mote trailsDensity · Particle budget · Radius · Size · Speed · TurbulenceOpacity · Global brightness · Trail amount · Trail fade · WindCustomize each style and layer independently, including tint, brightness, lifetime, motion and trail settings.Enable or disable layers to suit your scene.💾 3 Ready-to-Use Profiles:Pollen & Spores · Floating Dust · Ambient AshDuplicate the included profiles to create your own atmosphere variations.⚡ Performance-Conscious Design:Localized emission · Reused Particle Systems · Shared particle budgetBounded trail geometry · Optional layers and wind visualsTune density, coverage and trail detail for your target hardware rather than populating an entire map.🎮 Interactive Demo:Switch between all three styles and adjust the main parameters live.Free camera movement · Directional wind controls · Layer toggles · Hideable UIOpen demonstration scene with a world-space metric floor grid.📖 Documentation:English and Spanish documentation covering setup, component controls, profiles, layers, wind, trails, scripting API, customization and performance.⚙️ This Package Includes🌿 3 Atmosphere Styles — Pollen & Spores, Floating Dust & Ambient Ash🧩 1 Main Runtime Component — AmbientBiomeParticles; creates and manages its particle systems at runtime🎁 1 Ready-to-Use Prefab — camera-following atmosphere with the Pollen profile assigned💾 3 Customizable Profile Assets — one per style✨ 4 Independent Layers per Style — fine particles, detail motes, soft halos and mote trails; all enabled by default🎨 12 Style Layer Materials — four per style, plus wind and demo materials⚡ 3 Custom HLSL Shaders — procedural particles, wind trails and the demo floor grid; no Shader Graph🌍 World-Space Particles — localized emission follows a target or MainCamera, with configurable radius and forward bias💫 Organic Mote Wakes — independent soft circular motes deposited in 3D positions, with smooth drift, spread and fading🌬️ Directional Wind — degree-based direction, strength, optional wind wisps and optional directional Unity WindZone binding🎛️ Runtime Controls — density, particle budget, radius, size, speed, turbulence, opacity, brightness, trail amount and fade duration🔧 Custom Inspector — component controls and inline profile/layer editing📐 Scale Compensation — particle size, volume and movement adapt to Transform scale; uniform scale recommended🎯 Scripting API — profile switching, layer toggles, particle controls, brightness and wind setters⚖️ Bounded Budgets — up to 1,200 native particles shared across layers, residue and wind, plus a separate trail mesh capped at 2,200 motes♻️ Reused Particle Systems — six managed systems reused across style changes🎮 1 Interactive Demo Scene — live controls, free movement, Q/E turning, F1 UI toggle and an open metric-grid floor📖 English & Spanish Documentation🧱 Assembly Definitions — Runtime, Editor and Demo separated into independent assembliesAI coding assistants were used to assist with C# runtime and editor scripts, HLSL shaders, procedural particle and trail-generation code, and documentation. The generated content was reviewed, tested and iterated on in Unity under the publisher's direction. The visual targets, implementation decisions, testing and release decisions were made by the publisher. No AI-generated images, audio or imported 3D models are included; particle shapes are generated procedurally in shaders.
