After creating the standard asset library, we can need to import it into Unity to utilise them in our simulations.
Drag in the street furniture into the Unity scene.
Click on street furniture and uncheck box under the Inspector Tab → Model → “Import
cameras”.
Click “Apply”.
Click on the “hierarchy” tab, right click on the imported street furniture, and select “Unpack prefab”.
Select camera views (Front, Right, Top, Perspective) and delete. After this action, the “object” should only have street furniture component.
