Mapping Our Way to PBR | Writing Unity URP Code Shaders Tutorial [4/9] ✔️ 2021.3
✔️ Tutorial tested in 2020.3 and 2021.3
Have you ever wondered how lighting and shadows work in Unity? Or, do you want to write your own shaders for the Universal Render Pipeline, but without Shader Graph? Either because you need some special feature or just prefer writing code, this tutorial has you covered.
This is the fourth part in a series about writing HLSL shaders for URP. In this video, we take a look at PBR, or physically based rendering, and implement a variety of effects aiming to simulate different materials. By the end, we will support metals, glasses, glowing objects, plastics, and more!
