Introduction

What is Shiny SSRR?

Shiny SSR 2 (Screen Space Raytraced Reflections) is a high-performance real-time reflection system for Unity. It adds accurate, physically-based reflections to your scenes using screen-space raymarching - no baked probes, no mirrors, no planar reflections required.

Shiny SSRR works with both Forward and Deferred rendering paths and supports the Built-in and Universal Render Pipeline (URP).

Key Features

Raytracing & Quality

• Screen-space raymarching - accurate reflections without baked probes or cubemaps.
• Quality presets - Fast, Medium, High, Superb, Ultra with one-click setup.
• Binary search refinement - sub-pixel precision for sharp reflection edges.
• Temporal filter - reduces flickering and stabilizes reflections across frames.
• Contact hardening - close reflections stay sharp while distant ones blur naturally.

Rendering & Flexibility

• Forward & Deferred - works in both rendering paths on Built-in and URP.
• PBR workflows - choose Smoothness-Only or Metallic+Smoothness for accurate material response.
• Per-object control - add Reflections scripts to individual objects for fine-tuned settings.
• Volume system (URP) - Global and Local volumes for area-specific reflection settings.
• Skybox reflections - reflect the sky or a custom cubemap on surfaces.
• Transparency support - reflect transparent objects (sprites, puddles) via depth pre-pass.

Performance

• Resolution downsampling - render reflections at lower resolution for faster results.
• Dark Reflections mode - stylized look with reduced GPU cost.
• Stencil masking - skip reflections on screen regions that don't need them.
• Low precision mode - use RGBA32 buffers for lighter GPU memory usage.

Requirements
