Advanced Automotive Car Paint Shader!

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.
