Today, I will show you how to upgrade a standard project to URP project.
Create a standard 3D project. Add some GameObjects to a scene.
Go To Package Manager, Packages -> Unity Registry, and find Universal RP. Install it.
Create a new folder called Settings and create a Universal Render Pipeline Asset.
Go to Edit ->Project Settings.
Next go to Graphics, and assign the Universal Render Pipeline we just created.
From there materials in your project may turn pink.
If this happens, go to Edit -> Render Pipeline -> Universal Render Pipeline -> Upgrade Project Materials to UniversalRP Materials.
Everything should go back to normal.
