Rain VFX — Splash, Ripple & Impact Mist System · URP & HDRP

Tired of rain effects that just fall and disappear without ever touching your scene? This system reacts to your environment — every raindrop that hits a surface triggers splashes, ripples, and localized mist, so rain actually feels connected to the world instead of floating on top of it.

Built entirely in VFX Graph for Unity 6, this rain system gives you both ready-to-use presets and full manual control, in either Lit or Unlit rendering, for URP or HDRP.

━━━━━━━━━━━━━━━━━━━

☔ CASCADING IMPACT EFFECTS — Raindrop collisions automatically trigger splash particles, water ripples, and localized impact mist, on top of an atmospheric global mist layer covering the whole rain area.

🌐 AREA-BASED DENSITY SPAWNING — Set an Area Width and Area Depth and the system keeps raindrop density consistent per unit, so rain looks the same whether your spawn zone is small or large. A fixed drop-count mode is also available.

📐 CUSTOMIZABLE RIPPLE ANGLE THRESHOLD — Ripples spawn based on a configurable impact-angle threshold, letting you tune where on a surface they're allowed to appear.

💦 DIRECTIONAL SPLASH CONTROL — Splash particles use separate upward and radial strength multipliers, giving you control over how they scatter on impact.

🎛️ 45+ EXPOSED PARAMETERS — Full Inspector control over particle lifetime, size, velocity stretch, color gradients, spawn shape and physics, available in both Lit and Unlit variants.

⚙️ RUNTIME CONTROL SUPPORT — All exposed parameters (density, wind strength, color, spawn area, and more) can be changed at runtime through Unity's standard VisualEffect component API, so you can drive rain intensity, wind, or presets directly from your own gameplay scripts.

🧊 DEPTH BUFFER COLLISIONS — Raindrops use the camera's depth buffer to detect surface hits and trigger impact events — no custom colliders needed.

🎨 THREE READY PRESETS + FULL CUSTOM VARIANT — Calm Rain, Heavy Rain and Storm Rain for instant drag-and-drop setup, plus a Fully Customizable prefab exposing every parameter for advanced tuning.

⚠️ Note: this asset does not include a particle masking/exclusion system, so it's primarily intended for outdoor/exterior rain scenarios. Separate add-ons with interior masking support are planned (TopDown Masking, Shape/SDF Masking), split into individual packages so you can pick only the masking approach you actually need.

👀 Tip: check my publisher page — the masking add-ons may already be released.

🔇 No Sounds Included
