详细描述

Screen-space reflections (SSR) as a fullscreen post pass.

Reads the lit scene color, hardware depth (D32) and world normal, and for each pixel ray-marches the reflected ray in screen space. Where the ray hits geometry it emits the reflected scene color with A = hit validity, so a surface (e.g. Water) can blend it over an env-cubemap fallback.

Mirrors GlobalIllumination: manual fullscreen overlay (applyFromSceneTo). It does not auto-run in the default 3D path.
