Learn Unity Shaders from Scratch, Unity ShaderLab is how you create custom shaders. It comes in 3 flavours, fixed function, vertex-fragment and surface shaders. We won’t be looking at the fixed function route in this course as it is effectively a legacy option and you want to learn modern best practice. The code syntax is based on the C language, but fear not, we will assume you have literally no knowledge of this language at all and we will, as the course title states, learn this from scratch. A shader uses the GPU ( the Graphics Processing Unit) to handle multiple programs at the same time, so it is unbelievably fast. We will start from really simple examples and progress slowly through each stage of developing a custom shader. You will be able to play with the shader code using Visual Studio, or another code editor if you prefer. You can experiment with different values to see the impact it has on the end result.

Unity shaders are split into vertex shaders and fragment shaders and we will focus initially on the fragment shader, working essentially in a 2d environment. With dozens of shaders in the course resources you will learn the language in gentle stages. Before moving on to use Unity’s surface shader syntax to easily include complex lighting. Once you’re comfortable with simple shaders we will cover advanced effects such as tessellation, transparency, using the stencil buffer and post-processing. Creating your own shaders means understanding the HLSL language and that is the aim of the course. You could search for a suitable shader on ShaderToy or ShaderFrog and then try to adapt the code. But without knowing the language you’re going to find that difficult to do. To really be effective you need to know about the language, shaping functions, tiling and lighting calculations. To do this you will need to follow along with the course and complete the many challenges suggested. At the end you will then be able to create any shader that you can imagine.

What you’ll learn

The mysteries of writing Unity shaders
You will be gently introduced to how to approach the problem of creating a custom shader.
You will learn the full details of the HLSL shader language.
You will learn to use the Surface Shader syntax to add custom shaders on top of Unity lighting.
You will start with simple unlit 2D shaders and work up to advanced effects such as volumetric shaders and clipping.
Learn to create shaders that work with the Universal Render Pipeline (URP)
Learn to use Shader Graph to create your shaders

Who this course is for
