What is URP?

Its full name is Universal Render Pipeline, which is an official template provided by Unity based on SRP. Its predecessor was LWRP (Lightweight RP), which was renamed URP in 2019. It covers a wide range of different platforms and is built for cross platform development, with better performance than built-in pipelines. Additionally, it can be customized to achieve different styles of rendering, The universal rendering pipeline will become the foundation for rendering in Unity in the future. Like LWRP, URP enables developers to extend Unity's graphics pipeline through custom rendering processes and effects. Unlike ordinary shaders and effects, these channels are camera independent and can persist throughout the entire project without the need for settings for each scene.

URP is applicable to any platform currently supported by Unity.

Scenarios processed by URP

What are the advantages of URP?

1. Supports post-processing and has strong maneuverability. URP can perform more than ten different post-processing effects, which is more realistic compared to the original build-in pipeline scene.

2. Good performance, capable of rendering up to 8 pixels of light in one pass.

Performance consumption comparison

Comparison between URP lighting treatment and build-in:

1. In terms of performance, shadow processing is much better than the build in rendering pipeline.

2.Adding dynamic light to URP directional light does not incur additional performance overhead for Batches and SetPass calls.

Build in rendering pipeline:

URP：

It can be observed that URP has decreased by nearly twice compared to Batches with built-in rendering pipelines. Therefore, using the URP universal rendering pipeline for Unity projects can not only bring significant improvements to the scene, but also further reduce resource performance consumption. Currently, URP is widely used in various 3D projects due to its excellent performance and strong platform compatibility.
