Setting up a Unity Project for the High Definition Render Pipeline (HDRP)
If you have an existing Unity project that you want to finish off in the HDRP, this is the place to start.
First of all, I exported my game scene as a Unity Package. You can do this by right clicking on the scene in the Projects folder (in Unity), and then selecting the export package option.
In Unity Hub, a new project is created using Unity 2020.3.5.
Select the High Definition RP template, name your project and then select a save location on your hard drive.
The Hierarchy should look like this upon loading the default HDRP template.
There is a first person controller automatically setup, so you can push play right away and move through the default Unity game scene!
