You explain things very well! What most people miss out when making videos about subjects is they explain topics and then jump to another topic right after. You bring up a topic, give examples, explain it, reiterate what it is with references to real world items, THEN move on. Well done!

[@ZedaZ80]

I realized this when I was watching a (live) presentation a few months back. The presenter would start talking about a process and half way through, I'd realize "oh, this is really useful, what did she say this was called?" And then she would move on to the next thing @__@

[@qma2275]

- I don't have the words to express my gratitude for sharing such a detailed course for free. The university i'm studying to be a game developer at, which charges $1,500 a year, didn't even teach me the basics like C# interfaces and importing assets into Unity, let alone shaders. As a non-native english speaker i had no problems undertanding you, nor was i bored - I am insanely happy i've stumbled upon your channel and this video specifically. Perhaps my career will be built through you and what you do. Thank you in advance :)

[@sagitswag1785]

Sorry to say this, but if you are paying 1.5k a year and they don't even teach you how to use your engine or the language, you are wasting your money. I would look into a different university and perhaps a different major. Just getting a pure CS degree will make sure you have the fundamentals you need for gamedev. Before you learn shaders it's infinitely more important to have your fundamentals down.

[@CorporalDanLives]

This > College courses I’ve taken. Freya is awesome; also THANK YOU for editing these down from the original stream, this is utterly invaluable stuff.

[@selgesel]

As a newcomer I must admit that I was at first put off by the length of the video, and wondered why she wouldn't just cut it into parts and upload them individually. But when I did start watching, I got completely hooked. I don't know what kind of wizardry this is but the content just flows so incredibly smoothly and naturally that cutting the video into parts would ruin it. Watching great videos like this makes me want to quit my daily job to have virtually unlimited uninterrupted time so I could watch them anytime I want and focus on making a game myself.

[@nitroneonicman]

I took two semesters of computer graphics at college. While this series is nice it doesn't even cover what we went through in a single week of the course. The professor was a fluid physicist who had worked on computer graphics since the 80s. Needless to say he understood the deep inner workings of OpenGL and Vulkan. This video is alright if all you ever intend to do is write basic shaders in Unity. If you want to seriously be considered for a career in the game industry it's better you take an accredited college course. Shaders can be extremely powerful if you know what you're doing, in fact the entirety of Minecraft is generated inside a geometry shader, which I guess if you don't know what that is by watching this video then I guess that proves my point.

[@nadaelnokaly4950]

You're so skilled at distilling information on the fly, organized into a logical flow appropriate for listeners who may not be familiar with the subject, explaining jargon as you go rather than assuming everyone knows it, etc. That's an extremely valuable set of abilities! Thank you for taking the effort to create this content and share it!!

Well this is hands-down the most intuitive and in-depth content on shaders. Can't believe this is free. Freya absolutely knows what she is doing. It's like this information is rooted deep inside her skin and now she doesn't even need to think about it while teaching others. I can only wish and hope to be like her one day. Couldn't thank you enough for this.

[@xr_xharprazoraxtra5428]

⚠⚠⚠ATTENTION⚠⚠⚠ : do NOT change the input names of the vert and frag functions, let v be v, let o be o, let i be i, because in a later episode, one of the Unity Macros will rely on the single letter names, for example : [PART3] light Attenuation : Unity will expect you to have "v" as your meshdata / appdata, if you rename your mesh data as something else, Unity will say "Undeclared identifier 'v'" and because of this, I have been depressed for the last 48 hours (not exaggerated)

[@piotrek7633]

Never change the syntax even if someone who teaches you does it. why make your code harder to read when you can use the same naming everywhere? Use the standards

[@Xonatron]

Also read and learn from the error message. It’s always a hint.

Thank you so much for uploading this! I'm a web developer and have been building interactive stuff in THREE js for a few years and recently decided to delve into the world of shaders. It initially seemed like such a dense field of black magic. A lot of the content online is either super basic "hello world" projects or on the insanely esoteric end of the spectrum. Also the struggle with learning new languages is that it's difficult to know if the information you're looking at is bad practice or not. Coming from a js background, there's a lot of seemingly arbitrary functions and float values in the code on sites like shader frog that are without comments. Even thought THREE js uses GLSL, there is a lot of cross overs and this tutorial definitely cleared up a lot of my frustrations which was super helpful in wrapping my head around actual use cases of shader fundamentals. Thanks so much!

[@47Mortuus]

!!! PREMATURE !!! - People always seem to mean "optimization is the root of all evil" I'd like this to be a quote: "Writing code, particularly for real time applications, in a way that is poor in regards to performance from the ground up is the cause of a lot of unnecessary work which has to be done eventually anyways. If your entire application uses a branch to convert a boolean value to an integer, instead of dereferencing it as an unsigned char, guarded by an exception-throwing debug-only check which determines whether or not the value is outside of the interval [0, 1], you should go back to the beginning an learn how to encapsulate your high performance code in well named functions"
