I recently upgraded from Default RP to Universal RP and,
I didn’t get what I was expecting for the materials in my project. Most of the materials had changed to the color pink!
You must convert your materials to the URP.
To upgrade built-in Shaders:
- Open your Project in Unity, and go to Edit > Render Pipeline > Universal Render Pipeline.
- According to your needs, select either Upgrade Project Materials to URP Materials or Upgrade Selected Materials to URP Materials.
Note: These changes cannot be undone. Backup your Project before you upgrade it.
