 New node alert new cycles feature alert. Yes, not everything is easy these days There's a new node joining the node editor the shaded editor that will make our life so much simpler when shading hair So there is already a hair shader in blender But it takes a lot of setting up and the same concept that we had recently last year with the principal BSDF this latest this ultimate shader for PBR looking surfaces and skin and everything That same concept that was later also introduced for the principal volume shader, which makes making volume shaders easier Now it's applied to the hair So there's a principal hair BSDF that it's so much simpler and it just looks so cool So, yes, it's a new node and you will just find it like in the rest of like the the list of the notes It's called principal hair BSDF and it just looks amazing. Look, this looks like a render that will take ages but it's actually 40 seconds here and It's not only looks good, but it's also very very fast. So what are the settings? It's very simple just in the the nature of the principal It's a you have a few settings So the one that you're gonna use the most usually is one of these three models, which is the melanin concentration So you basically you basically set up a level of melanin on your hair So zero your full on albino and then you can go a little bit more and then you get this nice blonde hair The more you go it gets darker and if you go full on you get something like this I like to think that I am somewhere here instead No, so yeah, that's basically it with one slider. You can get this awesome Looking hair. Of course, you can apply more more text to it So you can make it a bit more red if you want to have it more of a Yeah, more red and you see the kid is so nice It's just naturally just looks good. And yeah, you can go not so and I remember these sliders the number that shows up Here is the safe numbers, but you can you can always just like go nuts So yeah, it's in input the number manually, but don't do it unless you want to go crazy with the colors Which you can if you want there is a tint color that will help you add a little bit of color variation on top of the melanin So you get a bit more of a yellow when people dye their hair But a bit a bit more natural looking if you want completely unnatural or just have full control over the color You can always change from melanin concentration to the direct coloring Version of the model of these principal VSCF which will override it will look completely with this color When would you use this? Well, maybe when you already have a texture that you in want to map into these node like as a color So that way it's so but he has a bit less control But it's not as natural looking as this is one actually has a lot more control Then the last one is very specific is when you want to like when you really want to have the one-on-one Like you're following a paper or something and you really want to have a more precise detail on it, but Otherwise go with the melanin concentration, which is much It's so easy to use you also have roughness so for to control how a specular your how the light distributes over your Over your strands and you also have right radial roughness which I Yeah, I would make it you can play with this to get the the shiny level of fit This is one of the few one of the great examples of How things should go you get the feature and you get awesome Documentation in the blender manual in docs.blender.org There's already documentation which you can follow just to see how each individual settings affect so it's so so nice So the other settings code you will add like a layer of like Specularity on top of it so you can have like more like a grease or gel or wet hair For example, you can control that and then the other settings like in this a refraction unless you're trying to achieve like more of a different kind of Thick hair like animal hair for example, you can change those but otherwise is the default settings are pretty okay, like the offset the offset basically I Was asking Hair scales I was asking Brecht about it because it was added like just now. So basically the offset will change the The angle of it of each scale so to speak but those settings you never change Just just go with this one's on top and then you can also add a random color This one here is pretty useful because you will add per strand an individual color difference on top of the melanin So it will make it a bit more More random, so it looks a bit more realistic And you can also change the roughness which is the same as this one, but random per strand So lots of options there But here on the top are the ones that you're gonna change the most and it's just so simple You don't have to add all the million notes that you had before so this is fantastic. It looks great it's based on a paper from from The same kind of hair that was used for Zootopia for example, so yeah You get you can get exact same thing, you know, it's Fantastic, so yes go test it. It's in blender 2.8 and it's also in blender master So the development version of 270 like the one after 2.79 that is still based on 2.7 that has That doesn't have the UI from 2.8, but still has a lot of improvements already has it So if you're working with that, you can already try it or just use 2.8. It's it's right there and Credits time. Yes, this is part of a Google summit of code It's the first project of 2018 to be merged already like summer is still going and it's already merged. So so cool Congrats Leonardo Segovia and Lucas Dogner as part of the Google summit of code. This is fantastic. So Yes, so exciting finally we have nice looking hair Nice greasy hipster hair. Ah, yeah speaking of history. Actually this this file has a few more Haircuts, so yes, thanks to Chris Chupa Chupka for this Blendfile providing this Blendfile to test so all these crazy hairdos and there is one here the first one I It's like a oops This one Nice Let me go here right there there. It looks like Our own character artist Julian. Yeah, it's awesome. Anyway Go play with this joke. You also should go play with this download blender 2.8 or the master version from today and go play with it. I Will see you again. Oh, yeah, by the way, I moved to a new office now. I'm standing actually can do exercise and stuff Okay, no off topic. I'll see you again in the next video. Ciao
