Unity HDRP

description Unity HDRP Overview

Unity HDRP is a rendering pipeline designed to produce photorealistic visuals within the Unity game engine. It enables developers to achieve high fidelity graphics suitable for demanding projects like architectural visualization and cinematic experiences. Primarily used by artists and designers creating visually rich games or interactive applications on PC platforms, it offers advanced lighting and material tools.

help Unity HDRP FAQ

Should a Unity project use HDRP or URP?

HDRP targets high-fidelity PC, console, cinematic, and visualization projects, while URP is designed to scale across a broader range of hardware, including mobile devices. HDRP does not support OpenGL or OpenGL ES, so it is a poor choice when those graphics APIs are required.

Can Unity HDRP use real-time ray tracing?

Yes. HDRP supports hardware-accelerated ray-traced effects such as reflections and also offers path tracing for supported high-end workflows.

Can an existing Unity Built-in Render Pipeline project be converted to HDRP automatically?

Unity provides conversion tools for materials and some project settings, but the process is not completely automatic. Custom shaders, lighting, post-processing, and camera behavior often need manual revision because HDRP uses a different rendering architecture.

Does Unity HDRP work on phones and WebGL?

HDRP is not intended for WebGL or mainstream mobile deployment. Developers targeting browsers, Android, or iOS normally choose URP because it supports a much wider performance range.
