Exporting our built-in render pipeline project

The built-in render pipeline is the default render pipeline in Unity. It is a simple and lightweight pipeline that provides basic support for 3D graphics and is suitable for most 2D and 3D games. It supports standard materials, forward and deferred rendering, and a limited set of post-processing effects. It also supports basic lighting and shadows, and a limited set of reflection and transparency features. We have done all of our projects in this render pipeline thus far, and that will continue in the remaining chapters, but here, we will cover how to take a project we created in the built-in render pipeline and export it to a project that is using either URP or HDRP. When we export the package, we will need to further configure the project to make it functional in the render pipeline of your choice, but this is the best option rather than converting the current project from a built-in pipeline into one that uses URP or HDRP.
