I have built up my project using Universal Render Pipeline and as required I downloaded Prototype Pack from the Asset Store.
Everything becomes pink when I opened the Demo Scene first time so as per my knowledge, I have upgraded objects materials to URP materials using Edit → Render Pipeline → Universal Render Pipeline → Upgrade Project Materials to URP Materials.
After this, all models started looking normal but the terrain doesn’t, here you have a screenshot:
As you are seeing Default-Terrain-Standard material not get changed so what to do for upgrading this material to URP?
