I’ve been googling for weeks trying to find all this information and now I’ve learned so much in just 3 hours! I cannot express how happy I am now! Thank you Freya!

The formula you highlighted to calculate the bitangent saved me from such a headache thank you!

Seriously, discovering this and you as an instructor/youtuber/person has revitalized my game developer pursuit process. XD Coming from someone who by all popular accounts and influences should technically not be pursuing this career at this point in my life, this means more than I can express in a youtube comment. Thank you so much.

Many people said this already, but thank you. This series has so much good stuff! One of the best (if not the best) series about shaders on KZfaq. Thanks again 💖

The best video series in the internet about shader coding. You got me into this stuff and i'm will be sticking with it for a long time!

I know it has been 3 years since making of this video, but I found this now and despite the fact that I don't use Unity and rather learn OpenGL and write stuff on my own as much as my skills allow, this has helped me a freaking lot! Thank you Freya! :))

You just helped get me through comprehending an issue I was having today in a pixel shader, and I thank you sincerely for that. You clearly comprehend shader pipelines better than I ever did even back when I was interacting with them daily, and you cut right through the decade or two's cognitive oxidation that has built up since.

If you'd made this series 10 years ago I might still have my hair. This is exceptional!

This is amazing. Came here for a whole different issue, but now I have been watching for an hour....and will come back! :D

I really thank you for these explanations. Online you can find scattered information here and there, but I haven't found anyone who allowed me to join the dots one by one. These are really great lessons. I can't wait for the next one.

I wish my teachers wore cat ears

I remember self teaching this in my first year of uni. Not sure why I gave up on game dev but after 2 and a half years, I've been catching up on it. This helped me speed through.

well, these were 9 hours very well spent. tied up a lot of loose ends of information i found in bits and pieces over the years. p.ex i knew what a normal map was used for, and that it supposedly contained the 3-axis lighting information inside its rgb, but seeing it implemented in the shader made me understand what normal maps actually are. or these refracted specular highlights, such a beautifully simple implementation. from something obscure and unreachable to simple and elegant. thanks a lot freya.

This serie about shaders is amazing, just as all the other series and Freya's teaching skill. Thank you!

Amazing tutorial, thank you! I now finally _understand_ how all this works! What would be amazing would be a follow up course that shows how to do all this with Unity's built in functionality!

This tutorial series has been extremely helpful. Thank you so much for uploading these! I have been learning this stuff on my own, for over two years now, and it has been quite cumbersome. Your examples and way of explaining really help putting thing into perspective. One thing to (maybe) consider in the future: I like designing simple meshes from scratch and start from there explaining the data flow to the final pixel. I found that to be very helpful in designing effects - because it gives a whole new dimension of possibilities. One easy example could be a billboard Line-Mesh, using uv2 for vertex displacement (line-width). But anyways... Thank you

Don’t have any ambition to code shaders, but love playing around with shader graph. This series has helped me a lot to grasp some of the fundamentals a lot better.

Thanks for the awesome videos Freya Holmér. If I ever release anything I'll have to put you in my credits as a special thanks.

Great video series, I revisit these often when I get stumped on my shader coding and need to refresh myself on a concept. Thanks!

thank you :) I've basically watched all your videos and they are a grand help. You're amazing! I should do something like this one day

This tutorial series is so sweet!

Thanks Freya! You said something that was key to me fixing my bug. I didn't know that normal maps had a 'w' component for flipped UVs!

"Oh no my water, its broken" LMAOOO

Great video series! I'm really learning a lot. Thanks for putting all of these up for free!

Awesome finale of the series! Thank you for these in depth educational videos.

I cannot express enough thanks to you Freya for these series. Great material and perfect explanations.

thank you for sharing your knowledge and thanks to the students letting you upload it.

You and your content are pure GOLD. Thank you!

This was such a great explanation! Thank you for this!

EVERY TIME I HAVE TO TRANSFORM SPACES MY HEAD EXPLODES EVERY TIME OMG

You are appreciated.

Thanks for uploading a new video ... I've been waiting for so long

This is such an amazing resource, thank you!

Exactly something I was looking for great work!

In the Outro, you showed the water ripples caused by that x axis texture. My only question is, how do you position the center of the texture to the actual spot where the ship and water mesh converge? Thanks

⚠⚠⚠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 one of the Unity Macros will rely on the single letter names, for example : 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)

At 2:41:35, I didn't understand what you did exactly to hide the mip seam, could you elaborate? I'm curious because the result is very nice, and I work a lot with rendering engines, and how we usually solve this is to simply make the texture tile infinitely, so when the first row/column of pixels gets mipped, it gets mipped with the last row/column of pixels, and vice versa, for both U and V axis. So, long question short, that "a bit of a hack" you did, was that to tile the texture?

Greate tutorial series. Thank you!

Thank you for sharing your knowledge it's priceless !

Thank you, learned a lot.

Thanks a lot for all these videos!

This is my first time in this channel. I am a 3D artist and an AR filter creator and work as a freelancer. I want to learn game development and the content here looks very helpful for me. Please, can you tell me your learning path? books? online courses? documentation? or any recommendation?

Really nice explanation of normal maps. Tangent space is still a really weird thing to me. But the part where you created tangentToWorldMatrix was one of the things that were enlightening - such a good var name 🤝 . In other tutorials they called it TBN or used other fancy words and it was meaningless to me. I know i probably didn't read enough about it but cmon...

Thanks again Freya for making this available for everyone, so much value!! By any chance do you have anything related to HDRP Shader creation somewhere?

Very informative video!

You're a champion 🏆

What an incredible series, thank you so much!! Do you tend to create everything from an empty unlit shader? What if you don't want to go through the hassle of implementing all basic lighting again? Would you make a standard lit shader instead?

Idk who you are but i watched you while sleeping apparently

You are doing great job please keep it up

Is your opinion about using BRP over URP or HDRP because of the greater handwritten shader customizability still up to date in 2024 ? Awesome video series, thanks for that !

Tetrahedra can absolutely fill a 3D space. We use volume meshes made exclusively of tetrahedra for computational fluid dynamics.

Incredible, thank you a lot! 🙏

really great course! do you have plan to make a tutorial about post processing in shaders?

I wanted something good on IBL for a long time! Thanks Freya!

Great video like always! I think showing a Project or even having it on disk from a company you don't work for anymore is risky. I used shadergraph, but the shader didn't support ui masking. You can get the generated shader and I fixed it by hand in the generated shader. I saw those 8 passes. I think it is hard for them to fix this. They don't want to break all custom shaders.

Totally love watching you videos! Is there a way I could start to learn writing shaders from scratch basics and how to create light shaders for other softwares like Maya, Houdini? And would you be able to guide me as to how I can approach this?

Cute cat ears brought me here :3. Went out learning something I needed to know ;3 keep making videos 😻 they really help Nya ;3

thanks Learn a lot.

38:17 it calls preprocessor directive

Thank you!

cat girls cat girls whatcha gonna do whatcha gonna do when they teach shaders to you

Thank you! Freaking FINALLY someone explains what tangent space is. People are so bad at explaining, they either gloss over actually explaining the what it is and just says what it is used for, sometimes also skipping over the how it is used. OR you find the mathematical explanation which is as academic and unexplanatory as can be. It is so stupidly simple and now all the issues I been reading about makes sense, but this is what I needed to know first and that was what they always skip over even when they promise to explain it. Freya always delivers!

Damn this is so valuable i dont even have words! i was just wondering, where is the finishing part about receiving and casting shadows? i need it! or would you just not make an unlit shader if you want shadows + cast shadows? I want to make a toon shader in hlsl this time around because i made one using shader graph last year but heard from game devs that someone who has experience with hlsl is far more attractive than someone only experienced with shader graph. i did manage to get casting shadows to work fairly easily (but not perfectly), but now im faced with the issue of receiving shadows.. spent 4 or 5 hours messing up my code and rewriting a lot of stuff trying to mash together information from your courses and a separate source without luck. would appreciate it a lot if that would be something you could cover in the future as i havent found a video like that from you as of now. the other source i was using was made by Jasper Flick from Catlike Coding but some of the macros didnt seem to work or had been replaced :/ much love!

float3 Blinn = saturate(dot(H , N)) + _Gloss * (Lambert > 0); is it more optimize than using pow function ?

PS: 1:06:20 - sometimes "bitangent" are also known as "binormal" 2:52:34 - sad thing about IBL is that when you rotate the skybox around or you change the color of the skybox, the shader will not take account for that

Simplesmente incrível!

I wish I had the knowledge you have.

Ok I need more

Could someone please point out the math video where Freya taught about mapping direction to rectilinear which is mentioned around 2:37:40.?Thanks

Thank you!!!

Just finished the series. What would be the best next step to become a shader master like Freya?

I started support you on paternon for staff about shaders, it's so great, I have watched all your videos about it, but I want learn more, coudl you recomended antother materials about shaders, like videos or books?

How do you go about correctly increasing the intensity of a normal map past 1.0?

for the 'footsteps in snow'-example, I wonder how you would understand the position in uv-space from the intersection with the player. i had a similar question once when trying to implement a 3d painting tool. also, i assume you would have to feedback the displacement-texture with itself to be able to keep on adding footsteps, would you do this by rendering it to a rendertexture and then reading from it, or is there another way of doing this?

1:03:11 i was discussing normals and tangents with a friend, i have personally only used these when writing a ray tracer, and i don’t see why you would export the tangents along with the normals for certain occasions, UE also provides an option to parse tangents when loading a mesh, and i was thinking there must be a reason for it, would you know?

Freya i lovee you As a student

Thank you very much for your explaination , just perfect! , I try to create à bevel shader for unreal . do you have some url or information how to achieve this? Thank you

2:44:21

I could not get the point lights to work, or the normal mapping : / I wonder what I'm missing, if I find it I'll reply here

Thank you for your streams with explanations, they help a lot! Do you understand c# code? If so, could you explain how the hsv gradient fills the triangle in this code? I'm trying to do this in ue4 materials! stackoverflow - HSV triangle in C# I apologize for the off-topic question, and also for the fact that I can’t insert a link, KZfaq deletes the comment!

HELP 🔴🔴🔴: for the part "TRANSFER_VERTEXT_TO_FRAGMENT(o);" part, it keeps on saying there is a undeclared identifyier "v", what it's going on ? QAQ

What tablet are you using for drawing? Please asnwer me

How can I make an object receive shadows?

Where do I learn this stuff from 0?? x_x

hey do you think we should use urp in new projects?

You should've been working for a triple A studio

The y-coordinate on the rectilinear thing bent my brain a little thinking about the difference between a y-coordinate in a vector and its corresponding angle, and I am still wondering which of the 2 spaces the skybox image is actually encoded in. Does it look noticeably different if you take the arccosine of the y coordinate and divide that down?

Hi Freya, I followed the way on youtube to render a 2d pixel role with a 3d model like dead cell, but how can I create root bind to fixed positions on role used for fluttering scarf and fire in head?

please redo in HLSL for URP

is bitangent=binormal?

So cute ears !!!
