Leaves VFX — Physics & Aerodynamics System · URP & HDRP

Bring autumn to life with a falling leaves effect that doesn't just drop straight down. This foliage VFX system makes autumn leaves glide, tumble, and react to air resistance like the real thing, then wobble and settle naturally when they hit the ground. Built entirely in VFX Graph for Unity 6, this system includes ready-to-use prefabs and fully customizable variants, in Lit or Unlit rendering, for URP or HDRP. ━━━━━━━━━━━━━━━━━━━ 🍃 REALISTIC GLIDE PHYSICS — Independent drag values for flat-side vs. edge-on airflow (DragFlat / DragEdge) make leaves fall faster when edge-first and glide/slow down when falling flat — real aerodynamic fluttering, not a random wobble. 🌓 FLIGHT-ACCURATE LANDING ORIENTATION — Settled leaves land oriented based on the actual surface collision normal, preserving the side they were facing while falling — no random flip on impact. ☄️ GROUND IMPACT MOTION — Settled leaves play a decaying wobble and stretch/squash deformation on landing, instead of just stopping in place. ⛰️ STEEP SURFACE FILTER — A customizable slope-angle threshold controls whether leaves can settle on steep or vertical surfaces, so they don't stick to walls unnaturally. 🧊 DEPTH BUFFER COLLISIONS — Leaves use the camera's depth buffer to detect surface hits and trigger settling and ground-impact motion — no custom colliders needed. 🍂 35 LEAF TEXTURES — 35 optimized square textures across 6 tree types (Elm, Linden, Maple, Oak, Sweetgum, Willow) in various autumn color states. Drop in your own custom square sprites just as easily. 🪄 3 DISSOLVE MODES — Settled leaves clear from the scene using Alpha Fade, procedural Noise Dissolve, or Shrink, with fully adjustable durations, to keep performance under control. 🧩 FOLIAGE DIVERSITY SYSTEM — Blend up to 5 different leaf variants in a single VFX Graph with customizable spawn weights to break visual repetition. 🎛️ 65+ EXPOSED PARAMETERS — Full Inspector control over spawn shapes, aerodynamics, forces (wind, 3D noise, turbulence), settled behavior, and dissolve, organized into 11 categories. ⚙️ RUNTIME CONTROL SUPPORT — All exposed parameters can be changed at runtime through Unity's standard VisualEffect component API, so you can drive leaf density, wind, or settings directly from your own gameplay scripts. ━━━━━━━━━━━━━━━━━━━ ⚠️ This asset does not include a particle masking/exclusion system — it's built for outdoor/exterior scenarios. Separate interior-masking add-ons (Top-Down Masking, Shape/SDF Masking) are planned as standalone packages. Check my publisher page — they may already be live. ⚠️Note: Wind, 3D Noise, and Turbulence are self-contained internal forces — the system does not read external Unity forces like WindZone by default. 👀 Tip: check my publisher page — the masking add-ons may already be released. 🔇 No Sounds Included This asset contains visual effects (VFX) only. 💬 Need Help? ━━━━━━━━━━━━━━━━━━━ If you encounter any issues or have questions about the asset, feel free to contact me via Discord or Email.
