Rain-soaked HDRP scenes with no material changes: wet surfaces, puddles with ripples, drops on every object and glass, runoff, rain, splashes and shelter under roofs.**Downpour makes any HDRP scene rain-soaked without touching a single material.** It works through HDRP Custom Passes, so it applies to every object whatever shader it uses: your own Shader Graphs, store assets, terrain and characters. Streets darken and gloss, puddles fill the low spots, drops run down walls, glass and cars, eaves drip, and everything under a roof stays dry.**🌧 Wet Surfaces, Any Shader**- Porous materials darken, everything turns glossy, painted and polished surfaces keep their look.- A water film on level ground: wet asphalt gets a sheen instead of glitter.- Runnels of water down walls; reflections from HDRP's screen space reflections.- Forward-only materials (hair, fabric, StackLit) get a water-film sheen.**💧 Puddles & Ripples**- Random, round, irregular puddles that fill dips and gutters, decided in world space: same outlines from any distance.- Soaked rim around each puddle, deeper darker water in the middle.- Raindrop ripples, plus rings where drips and footsteps hit the water.**🫧 Water Drops on Every Object**- Drops cling, slide in stick-slip bursts along wandering paths, and leave trails and residue beads.- Beads only on water-repellent surfaces (paint, metal, glass); porous materials soak the water up.- Hanging drops under free edges. Consistent on curved surfaces; no distant sparkle.- Glass and transparent materials get drops and trails too.**🚗 Moving Objects & Characters**- Drops ride along with characters, vehicles and physics props.- Each moving object soaks up in the rain and dries gradually under cover.- Footstep rings and splashes.**🏠 Shelter, Runoff & Drips**- Roofs, awnings, bridges, glass canopies, car interiors keep what's under them dry. No colliders needed.- Drops that reach a free edge fall and splash, exactly where the drawn drop leaves the surface.- Eaves and awnings drip from a few points, like real gutters.**⛈ Rain, Splashes, Haze & Weather**- Refracting rain streaks with wind and gusts, hidden under roofs.- Raycast splashes that land on roofs and characters.- Rain haze lowers visibility with the rain.- 5 presets (After Rain, Drizzle, Shower, Downpour, Storm) blended at runtime; dynamic soaking and drying.**🛠 Workflow**- One controller component with a tab per feature, each with its own Enable switch.- Setup Wizard checks your project and fixes it in one click.- Scripting API: start/stop rain, presets, "is this spot sheltered / how wet is it", ripples, events.- Playable showcase street (walker, free camera, weather panel) and a minimal demo.- PDF documentation.
