Realtime Reflective Surfaces

Realtime Reflective Surfaces is a URP reflection package for flat reflective surfaces such as water, polished floors, mirrors, glass, and stylized reflective materials. It provides a renderer feature, global volume override, per-surface component, screen-space reference reflections, stable planar reflections, quality presets, debug views, and sample scenes for floor and water setups. The included Shader Graph sample demonstrates distorted planar reflection sampling through _VATReflectionPlanarTex. Real-device mobile test reference: on a MediaTek Dimensity 9000 device with 12 GB RAM, the sample scene stayed above 80 FPS with Planar Reflection at High Quality, while Screen Space Reference tuning from High to Low kept the frame rate roughly between 30 FPS and 80+ FPS. Mobile performance numbers are provided as reference results from the included Unity sample scene; no standalone mobile demo app or device-specific demo project is included.
