# Render graph system in URP

> Resources and approaches for using the RenderGraph APIs to create a Scriptable Render Pass.

The render graph system is a set of APIs you use to create a [Scriptable Render Pass](/engine/6000.0/manual/render-pipelines/universal-render-pipeline/customizing-urp/intro-to-scriptable-render-passes.md).
