Convert a project from the Built-in Render Pipeline

The High Definition Render Pipeline (HDRP) uses a new set of shaders and lighting units, both of which are incompatible with the Built-in Render Pipeline. To upgrade a Unity Project to HDRP, you must first convert all your materials and shaders, then adjust individual light settings accordingly.

Topic	Description
Convert post-processing scripts	Remove the Post-Processing Version 2 package from a project and update your scripts to work with HDRP's own implementation for post processing.
Convert lighting and shadows	Convert a project to physical Light units to control the intensity of Lights, instead of the the arbitrary units the Built-in Render Pipeline uses.
Convert materials and shaders	Upgrade the materials in your scene to HDRP-compatible materials, either automatically or manually.
Convert project with HDRP wizard	Add the HDRP package to a Built-in Render Pipeline project and set up HDRP.
