Problems that the Scriptable Render Pipeline solves

If a Render Pipeline is a number of steps that an engine performs to render onto the screen, a Scriptable Render Pipeline is a pipeline that you can control from Unity scripting code to render the way you want it to.

The Problem

Traditionally, Unity provided a number of built-in pipelines that you can use. This includes the Forward renderer which is better for mobile and Virtual Reality, and the Deferred renderer which is better for more high-end applications. These out of the box rendering solutions are very general black boxes, that comes with the following downsides.

• They only do what they are designed to do.
• They are general, which means that, because they need to do everything, they are masters at nothing.
• They are not very configurable. They are black boxes that you can inject rendering commands to at pre-defined points.
• Extension and modification is prone to error because small internal changes can have large outward ramifications.
• Unity can not fix many of the bugs because this changes behaviour, which can break Projects.

The Solution

The SRP Core API resolves the problems described above. It changes rendering from being an inbuilt black box to a controllable, per project, scriptable concept. You can use the SRP Core API to control how Unity renders to the screen, from low to high level.
