A high-quality real-time automotive car paint shader featuring metallic flakes, iridescence, holographic prism effects, rain wetness, built for Unity URP and optimized for real-time games.This package provides a production-ready advanced car paint shader designed to achieve realistic automotive finishes in real time. It supports metallic flakes, layered clearcoat, iridescent and holographic effects, rain-driven wetness, and stable specular highlights, making it suitable for racing games, vehicle showcases, configurators, and AAA-style projects.The shader is built for Unity URP and focuses on visual quality, performance, and artistic control. It allows creators to replicate a wide range of real automotive paint styles — from OEM metallic finishes to custom pearl coats, flip-flop colors, and black holographic prism flakes.The system is fully customizable, supports dynamic weather effects, and includes specular anti-aliasing to reduce shimmer and flicker, ensuring a stable image in motion.Designed for real-time gameplay, not offline rendering.Key Features🎨 Advanced Car Paint RenderingMetallic flake layer with flake normal mapsAdjustable flake size, intensity, and sparkle responseRealistic automotive reflectance response🌈 Iridescence & Pearlescent EffectsView-angle color shiftingRamp-driven iridescent color controlPearl and flip-flop automotive paint presets✨ Holographic / Prism FlakesRainbow holographic sparkle effectHighlight-driven prism color shiftsRealistic black holographic flake simulation🌧 Rain & Wet Surface SystemDynamic wetnessRain droplet normal blendingSmooth wetness transitions without popping🧠 Specular Anti-Aliasing (SpecAA)Reduces shimmer and highlight flickerStabilizes metallic flakes in motionImproves temporal stability in real-time gameplay⚡ Performance-FocusedOptimized for real-time useMobile / Switch-friendly scalabilityNo heavy ray tracing or screen-space dependenciesRender Pipeline✅ Unity URP❌ HDRP not required❌ Built-in pipeline not requiredShader TypeShader Graph–based coreHighlight sparkle shapingCustom HLSL functions for:Specular AAFlake smoothness responseLighting ModelPBR Metallic workflowView-dependent Fresnel controlsInput SupportBase color (albedo)MetallicSmoothnessFlake normal mapRain map (packed)Iridescence ramp textureHolographic ramp texture
