Introduction & Setup2:30
An introduction to myself, why rendering, and the initial setup that you need to begin this course.
Unity Setup and how to go through this course3:59
This is how I've set up everything in Unity, remember, while I will give you all the course material, write your own shaders!
Introduction To The Shader Structure18:17
Welcome to the very first lesson of the shader course. I want to start right away by jumping into the basics of the shader. I will be going over exactly, line by line the core structure of a shader. It is unlike any other programming language, and strange to many programmers, so dive right into it.

Sampling A Texture 19:01
Here we will be doing our very first texture sample! We will be learning UVs, what they mean, and how to use them to display our very first texture.
Sampling A Texture 29:29
Once we got a handle on how UVs work, let's use them to sample textures. But more than that, we can also learn about how to transform and scale textures while we are at it.
Transparency and Blending14:47
Let's learn about transparency or ideally, blending. Blending is how all transparencies work across all games and even different game engines. So let's learn about the blend formula.

UV animations, transform, sliding17:13
In this lesson, we will be learning about how UV animations work, how they slide, and how they animate
2 Texture Samples17:29
Two texture samples? Why would we ever do that? There are many reasons why and how a 2nd texture can support the first one.
Texture Erosion13:07
Texture erosion. This is a cool-looking effect that helps make objects disappear. It's not the easiest to explain in the description, so just jump right in!
Texture Erosion Advance13:48
One of the really cool ways you can make erosion look even more awesome is by adding these searing colours.

Animating Textures along UVs, Ideal for flowing streams in 2d17:38
Here we are going to animate a specific texture along with another texture that represents a UV. If that doesn't make much sense, check out the lesson, it will be much clearer.
Animating Distortions & Warps7:55
Doing distortions and warps, concepts are similar to previous lessons, but what can we really achieve with these skills?
Mathematical UVs - Whirlpool effects19:24
Creating UVs not from texture, but from math. That way, the UVs are perfect with no pixelation, and you can still do cool effects!
Masked Distortion6:07
You don't want to have distortion everywhere, let's mask it and work with it

Diffuse 3D Shader, basic lighting12:56
In this lesson we will cover the basic's of setting up a 3D shader, involving lighting
3D Shader, that takes in light from probes9:55
Now let's also make sure we get ambient lighting, lighting from the light probes and global illumination.
Moving lighting from vertex to fragment4:24
Notice a small issue here, we should have lighting done in the fragment for that extra smooth look

Description

Write Unity CG Shaders From Scratch (2D, 3D)

Have you ever wanted to write your own CG/HLSL shader code from scratch? Do you need help with understanding the intricate details of what happens on the back end? Learn to write shaders without the help of the material editor, and rather use the material editor as a prototyping tool?

In this Unity CG course, I will be teaching you the fundamentals of shader code so that you can write, create and develop unique looks that not only look amazing but run optimally too.

These techniques can be used for personal game development, and I will also go over best practices that can be used on the job in larger game companies.

My name is Benjamin Swee, your course instructor. I have been working at various game companies and been a Lead Rendering Engineer on popular titles such as Marvel Contest of Champions, Fast and the Furious games, & a few Lineage titles.

My role was often solo, as such I would create complete in-house rendering systems.

In this course, I not only want to bring you creative thinking when it comes to rendering, but also real-world industry experience, and the best practices that are used in titles that are launched today.

Shaders are a black box to many, I aim to unbox it

Note that this course is a work in progress. I plan on continually updating it. Let me know in the course messages, what moreyou want to see!

Who this course is for:

Beginner programmers
New Game developers
Developers who think CG shading in Unity is a black box
Anyone who wants to become a rendering engineer
