If this guy didn't make tutorials maaan I'd be so lost in blender

Things to never forget: 1) mitochondria is the powerhouse of the cell 2) everything has Fresnel

WHAT DO WE WANT? - SLIDERS! WHERE DO WE WANT THEM? - IN THE NODE EDITOR!

Speaking from the future, this was still useful because now I know what the iOR setting is in the Principled BSDF shader, as well as gaining a better understanding of the various settings I can use.

Rewatching this really makes me appreciate how far 2.80 has improved upon every previous version so significantly. And I'm sure some of these videos have influenced the major changes that were introduced beyond 2.79.

16:00 : Oh so I just have to add a fresnel node, great 20 min later : what the hell

I don't use Blender very often anymore (busy with work), but I still enjoy watching your videos. Thanks for making these comprehensive tutorials for all these years.

Me: *start making the node on my own as the video keeps going* Andrew at the end of the video: you can download the .blend file, so you don't have to do it on your own! Me: ... but I'm a wiser man now!

Returning to this video after what must be 5 years now. I was spoiled to be able to have such nice materials back then (even if I didn't know how to use them), and now I am looking back to see if my understanding of all this goes up with my maturity. Thank you so much for this two-part series, it has changed my perspective forever.

im going to need to watch this a few times for it to sink in

Thank you so much for all of your work and for what you bring to the whole Blender experience. Your humility and sense of humor are much appreciated. Cheers.

Clear and well explained. You increased my knowledge about blender textures by like 200% with this 1 hour.

Andrew Price is my hero! :) I am starting to produce legit animations, thanks largely to Andrew, and this is exactly the video I need to clean up my renders and give them a professional look. Keep up the good work Andrew, and have an amazing day!

"will npc in fps 4 food!!" I didn't even notice that the first time around. That's amazing XD

Thanks ! Even though I got lost halfway through, I managed to understand a little better when I got my hands on the actual PBR DIELECTRIC node, keep making these tutorials because they are really helpful !

Thanks for this Andrew, it's exactly what I needed for my current project! No more guesstimating how to use PBR maps with Cycles.

Man Andrew, greatly appreciate all your work! You are making blender easier for many artists :)

Awesome tutorial! I like your delivery style - technical without being condescending or arrogant. Excellent!

he makes mistakes and casually accept them and then corrects them... that's why he is the best guru

Dude, this tutorial opened a completely new world to me. Amazing! Thank you and keep up the great work!

Best Blender tutorials on KZfaq, period.

The most structured and detailed tutorial i ca across until now. Thank you very much!

Great job, it shows a very thorough research and a virtuous spirit for sharing it all with the community. Many thanks again, for another good lesson.

Effective, most effective. Thanks for the awesome tutorial, this spared me of an estimated 200 months of trial and error!

I knew that all of this wouldn't absorb the first watch (almost done), but I have learned so much from this and your other videos. Thank you!

Just something helpful, unwrap spheres from the top orthographic view. Then in the Add UV Sphere options, set the direction from view on equator, to view on poles. If you accidentally do it after having the image selected, then just uncheck the correct aspect box. Hope this helps. This was big help in making my OpenGL PBR node. Thanks Andrew. You've done it again

You'r a real Blender Guru, love you man!

I'm a big fan of your videos. I enjoy your all your tutorials even the incorrect ones. ;) You are a particularly good teacher and you are quite fun! Here is a small remark on this particular video: I don't understand why you chose to only raise to the power of 2 in the math nodes. I understand that it look simpler, but the correct value should have been 2.2 (as explain in your reference, RealLifePudding). Since you are not going into details of the math and just giving the answer you could as well have given the correct value... Here is the math for the viewers who cares : The variation that we want to obtain is y=x. However, Blender, by default, give a variation of y=x^(0.4545) or y=x^(1/2.2). If we raise this variation to the power of 2.2, y=(x^(1/2.2))^(2.2), it can be simplified to y=x^(2.2/2.2) or y=x^(1) or y=x. If it is raised only to the power of 2, y=(x^(1/2.2))^(2), it can be simplified to y=x^(2/2.2) or y=x^(0.9090). While this is close to a linear variation and a valid approximation to be useful in Blender, it is not perfect... Anyway, I could be wrong myself. I'm not a CG artist and I have look in the subject only briefly. On another subject, I work in nanotechnology and dielectric (or insulators) and metalic (or conductor) are therms that we use often. I must say that I find it quite amusing to ear those therms in a non scientific context. Also, the index of refraction (IOR) is a value that we use a lot. While it is true that a lot of materials have an IOR around 1.45, there are a lot of material that don't. Here are some examples of dielectric IOR that I know from the top of my head : water = 1.33, resists = between 1.5 and 1.8, silicon nitride = between 1.9 and 2.2. Needless to say that I would have liked to be able to change the IOR from the "supernode", but once again, I understand why you did not chose to bother... All that, just to say thank you for all your tutorial. They are great!

Thank you for the thorough walk through and explanations. Even better - the download. I really appreciate all you put into this.

I spent two months without blender and I missed you :))) .

This looks great! Looking forward to taking my shader skills to the next level.

Awesome tutorials! I have learned basically all I know about blender from your stuff! Thanks so much!

you're videos are so helpful, dont know what i would do without them.

It was quite difficult to follow this from around the 30 minute mark up to 42 minutes (for a relative newbie anyway) but it worked for what I needed; it just took watching that part about 4 times. But now it's done, thanks for the help.

Blender guru you are a great resource to the blender nation..

Thanks for that tutorial, this really helped me to understand the concept of PBR materials.

An hour long tutorial I didn't skim through. Nice!

Your a GOD for this. I've always supported your channel and I love your content. Your the best Blender Guru.

This is masterpiece. I don't have enough knowledge to be sure it's 100% accurate, but it seems to be, and I think it'll make my workflow way faster. Thank you sir !

I love your tuturials, you do a good job. Working on my first Decal package. Thank you.

Thank you ^^ I love your tutorials, they are complex but easy to understand and even and I never thought I'd say this about a tutorial funny, it's a pleasure to look it :D

I am new to Bender and 3D. Your videos make me excited about it. Thanks.

This is great. Andrew your hard work and perseverance is outstanding. i followed all of it although the math didn't make sense but the logic does.

A fantastic tutorial. Quite good quality instruction as well. Thank you for making it!

The best of the best. Our Guru. Thank you for all your wisdom. I love learning these things from you!

Really interested to see the Part 2! The metals are the ones that have been confusing me a bit lately. would be great to get some pro insight into that.

Love this guys tone.

Great work Andrew! Keep them coming

About half-way through I suddenly realised that what you were building later came to be in the Principled Shader, but this was like taking a peek under the hood of that shader to see how it works. And I really like your Less/More Slider. That could be a useful node.

Hi, thank you for such an educational and in-depth plus easy tutorials.

Your videos always teaches me new stuffs

On the plus side if you come to this years later you don't know what has come before :) thanks for the video :)

Thank You Andrew.....whatta legend, now off to part 2

i love you vids and i would be lost if poliigon and your channel weren't here. thanks soo much

Andrew, thank you so much for making these available to us! You're a ledge. I was wondering how one would link a Mapping node into the mix, to transform all of the Image Texture nodes simultaneously. Having to manually resize each one is becoming a real pain in the ass. Hope to hear back soon.

Thank you for your noble attitude of teaching your knowledge!

13:08 My mind is blown! Such a clear illustration! Thank you dear sir! I have one comment about this: past a certain angle, the light is *completely* reflected (Total internal reflection) - which is what fiber optics rely on :)

Wow, super useful! Thanks for the tutorial and the blender file. Great job :D

whao, that math thing at the end got me. Once this is understood it's actually quite clear :D Brilliant video, that helped a lot! Thanks for your great tutorials and additional explanations.

Awesome Andrew! You're really helping us.

Great tutorial Thank you. The node group is very helpful.. onto part 2

I realize how much work, research, understanding and knowledge have led to Blender being what it is today and what you and others like CynicatPro have contributed as pioneers. Thanks a lot for that! Beginnerquestion from 2021: If I wanted to in- or decrease the roughness in the principled bsdf shader do I still use the colorramp or Multiply/add overlay method or would a clearcoat simply fix this?

Most sincere kudos and congrats :). Very useful and well explained.

Thank you so much for creating this tutorial! Highly educational!

Nodegroups... is that another word for hell?

Fantastic! I've transposed your awesome tutorial to Poser 11's Cycles implementation and it works great. Thank you so much :-)

Much better. Thanks for putting in the effort. Still got some corrections about Fresnel, sorry. The Fresnel Reflection for tangential light (0° angle) depends on the Absorption, and the Reflection Coefficients of both materials, so the surrounding material (Air, Water, Oil...) and the material where the light is reflected. It can basically take any value, from almost 0% for water, 2-5% in commen plastics, to 100% for an ideal metal. In metals the Fresnel stays at approximately 100%. This is because in metals the electrons start to move arround in just the right fashion the compensate the external electromagnetic fields, effectively absorbing all the light. Due to the continuity relations for electric fields, this absorption leads to a high reflectivity. I hope this helps for the metals video, because, it's basically the same physics, just that the absoprtion goes waaaay up. Of course to make it more correct you would use multiple Fresnels, for the different color components, since gold doesn't absorb at all frequencies. So if you use 3 Fresnel filters for the RGB components, you should gain more control over the final fresults.

Just when I thought Blender couldn't surprise me any more, it turns out you can steal a slider from one node and use it in another node! :D

Damn, best video ever!! AND I WATCHED IT ALL! HOW??

39:12 "That is a very loud plane!" you are awesome

Soooo I've finished the whole beginner tutorial yesterday and I was like "That's cool, I gotta create my very own scene!" I was fired up and full of passion so I've quickly created some barrels, set everything up and I've decided to make those barrels metalic...I thought "Andrew will have tutorial! It shouldn't be that hard!" And here I am! At 39:00 , questioning my abilities to do anything and thinking about life and how meaningliess mine is... Alll thanks to node groups .___.

Omg, I've wanted to know how to make a PBR shader for a good while. :D

Love that you pulled an inaccurate video. Respect the professionalism.

fun to learn more about PBR texuring

I created some very cool pictures after I found this out, thank you guru!

I saw the original video. Could you name the main points were you were wrong? It would be helpful for me. Learning from mistakes is the best way to learn! Thx a lot for all your great tutorials!

thank u so much for your time the time and effort you put, is amazing overall cause you do it for free!

Half way trough the tutorial, and just had to write it down befor I forget, you are a awesome tutor, grate job on explaning, whis some of my profesosr where as good as you i think i would learn and would like to learn more about some stuff , again garet job

You are the man. Thanks for the upload!

"EVERYTHING has Fresnel" Vantablack: "Hold my beer"

This is so awesome. First I thought omg 1hour video for one material.. I'll just skip through it. But I guess i watched the hole thing about 2 times now. You explain everything so well that it is totaly worth it and I actually learned alot from it. You should definitly make more of these videos to explain nodes in action and what they actually do. Great Job!

Very nicely done! Thanks so much!

Thank you Andrew! You did a great job! :)

Thank you Andrew! Very useful

So glad we can download the file haha

46:50 It's because an unwrapped sphere is going to be 2:1 or 1:2. To cover the whole surface you must go 360 degrees around it one way (horizontally or vertically), but only 180 the other.

This Video is gold!!! Thanks Andrew!

Fantastic! I didn't realize how nodes could be mixed the way you did. I saw tutorials telling "just combine nodes of the same color and never mix them yellow with blue or gray, etc." But you are doing and is not a big deal! Why such (mistaken?) advice from other tutorials?

Awesome tutorial dude

you are the best guru ı ever see !!!

Thank you. Really top video helping me using PBR

Very nice work, will definitely check out more videos from you! :D

Great video, On to part 2!!

Top notch work.

Absolute legend. Nice one

I tried to control the fresnel with math node, I had some good results. The node script is a Time saver. Cheers

Thanks! This helps a lot it's a big tutorial but worth it.

Principled BSDF has made this obsolete

really clear, thanks very much ! it's very cool.

"And that's it fresnel!"
