Visit resource ↗Description
Unity's official package manual on docs.unity3d.com documents the High Definition Render Pipeline (HDRP), a Scriptable Render Pipeline for compute-capable platforms and physically based HDR lighting.
Coverage spans setup, volume overrides, lights, shadows, ray tracing, materials, Shader Graph, decals, sky, fog, water, post-processing, custom passes, and optimization tools such as the SRP Batcher.
HDRP and Universal RP are not interchangeable; the manual assumes an HDRP project. Intermediate Unity developers use it for pipeline-specific APIs rather than generic rendering primers.
Each package release has a matching doc set; @latest tracks the current line, but projects should open the version aligned with their Package Manager install.
Developers rely on it for exposure, adaptive probes, and frame settings; forums often link these pages when debugging version-specific HDRP behavior.
