How to: 2-Pass URP Shaders?

[george_boutwell]

Hey! New to graphics programming, dipped my toes in with simple one-hlsl file shaders like water and stuff. But I’m realizing one HLSL file doesn’t cut it for a shader that reads what is behind an object then renders the object based on that data from the earlier pass. There’s render objects and render features and render passes and render graphs and something always seems to be deprecated

Essentially, Im looking for a solid, up-to-date source of information on this stuff, or at least a place where I can learn how to ask the right questions, because like I said, graphics programming is a new and exciting world for me!

Thanks!

Understanding URP: A Beginner-Friendly Guide to Render Passes & Renderer Features

Hi! I’m Jemin Lee, a Partner Engineer at Unity. As we shift our focus from the Built-in Render Pipeline(BiRP) to the Universal Render Pipeline (URP), I often see beginners get stuck when migrating custom rendering logic (especially custom post-processing) to URP. Although our ebook, Introduction to URP for advanced creators (Unity 6 edition) covers most migration scenarios, this article focuses on a more beginner-friendly conceptual model: How the SRP/URP frame is structured Why URP behaves …
