High Definition Render Pipeline overview
The High Definition Render Pipeline (HDRP) is a high-fidelity Scriptable Render Pipeline built by Unity to target modern (Compute Shader compatible) platforms.
HDRP utilizes Physically-Based Lighting techniques, linear lighting, HDR lighting, and a configurable hybrid Tile/Cluster deferred/Forward lighting architecture. It gives you the tools you need to create applications such as games, technical demos, and animations to a high graphical standard.
NOTE: Projects that you make with HDRP are not compatible with the Universal Render Pipeline (URP). You must decide which render pipeline your Project uses before you start development; HDRP features are not cross-compatible between HDRP and URP.
This documentation contains the information you need to create applications using HDRP; including information on Lighting, Materials and Shaders, Cameras, and debugging.
HRDP is only supported on the following platforms:
- Windows and Windows Store, with DirectX 11 or DirectX 12 and Shader Model 5.0
- Modern consoles (Sony PS4 and Microsoft Xbox One)
- MacOS using Metal graphics
- Linux and Windows platforms with Vulkan
- Future: IOS with Metal, Android
HDRP does not support OpenGL or OpenGL ES devices.
Note: HDRP only works on these platforms if the device used supports Compute Shaders. For example, HDRP only works on iOS if the iPhone model supports Compute Shaders.
