The Universal Render Pipeline (URP) is a prebuilt Scriptable Render Pipeline, made by Unity. URP provides artist-friendly workflows that let you quickly and easily create optimized graphics across a range of platforms, from mobile to high-end consoles and PCs.
An earlier version of URP was called the Lightweight Render Pipeline (LWRP). URP replaces LWRP.
