How To Upgrade Your Project to URP in Unity

When opening a scene in a new project, the scene window looked like this:

It is because of the material. Normally the Shader should be Standard, but in this case it is URP, and Unity didn’t recognize it because it needs to be imported

Import the URP package in Window/Package Manager
In the next window, choose Unity Registry

Search Universal RP and install it

The gameobjects remain pink

In project window, RMB — Create/Rendering/Universal Render Pipeline/Pipeline Asset. Give it a name. I’ll call it ProjURP

Go to Edit/Project Settings and in Graphics, select the URP asset

If it doesn’t work, go to Edit/Render Pipeline and update the project materials
