Unity Certified User Artist Tests and Training Practice Test

Rendering pipelines determine how Unity draws each frame. The Built-in Render Pipeline is the original, fixed-function path that ships with older Unity versions, while the Universal Render Pipeline is a Scriptable Render Pipeline you install and enable for a project. They are not the same because URP uses its own renderer, shaders, and rendering passes, built on a different runtime path than the Built-in.

In practice, you choose one active pipeline per project; URP and Built-in cannot run simultaneously. Migrating to URP involves installing the URP package and creating a Renderer Asset, after which materials and shaders are converted to URP equivalents. Some assets can work across pipelines, but the pipelines themselves are distinct systems, so you shouldn’t expect them to be identical in behavior or features.
