## What it is
A reusable Unity URP RendererFeature implementing fast screen space planar reflections (SSPR) optimized for mobile GPUs. It renders real-time reflections on flat surfaces using compute shaders, requiring Vulkan support on Android.

## Use cases
- add real-time reflections to water or floor planes in a Unity mobile game
- implement screen space planar reflections in a URP project
- render cheap reflections on low-end Android devices
- make wet road or mirror-like surfaces reflect the scene in Unity
- improve visual quality of flat reflective surfaces without expensive SSR

## When to choose
- you need performant planar reflections on mobile (Vulkan Android) or PC in Unity URP
- you want a drop-in RendererFeature rather than building a custom reflection system
- your reflective surfaces are mostly flat planes like water or floors

## When to avoid
- your project does not use Unity's Universal Render Pipeline
- you need reflections on curved or non-planar surfaces
- your target Android devices only support OpenGL ES without Vulkan
- you need full screen-space reflections for arbitrary geometry

## Facets
- artifact type: library
- maturity: maintenance
- function: graphics, image-processing
