Intro To Shading Nodes in Blender 2.90!

how's it going guys so in today's tutorial i'm going to be showing you what i do in almost every single one of my node strings i'm going to give you sort of the basics of um what i what i like to do and the goal is that you can take these ideas and really expand them i get so many requests about shading and shading is a wildly complex things that something that would require like a three hour full course but what i'm going to give you guys is the bones of what i do every day that you can build off of and you can really try to learn and do some self-exploration with this but before i get into that let me shout out today's sponsor the sponsor for today's video is xyro xyro is a website builder that makes it extremely easy for anyone to create amazing websites and launch online stores that sell it really is the easiest way to create a website or an online store you don't have to learn to code to use xyro it's extremely fast to build and quick to load zyro is also the most affordable option on the market you never have to overpay for features you don't even use you can easily manage all of your businesses in one single place including selling on facebook instagram and amazon and as us 3d creatives we do like to sell a lot of assets and this is really good in the description there is a coupon code that you can use to get 30 off of your plan so you can head over to xyro and get your website going all right so i'm going to be using this fun little abstract scene i actually made a tutorial for how to make this on patreon you can go and get that in the description if you'd like but yeah we have this simple scene here and we're just going to start shading it so all of these things have the same material actually want to remove the material from the background and let's just give it a really dark color just to really separate the two and now this is of course the most basic way to shade i'm going to assume most of you know what you're looking at with this if this is your first ever video um you know about shading i would say watch a a pure intro course to explain to you what these do but i'm assuming a little bit of basic knowledge about this principled node but still this is going to be a beginner video so what i like to do is use these wonderful little tabs over here and i'm going to be using the shading tab right up here so here it is of course in terms of the models you want to use you can use any model for this we're going to be doing everything fully procedurally so everything we're doing wraps around any model so let's go and do my favorite string of notes i pretty much put a color ramp before anything now you can use math nodes but that's extremely complicated and no one really knows too much about those and i want to keep it as visual visual as i can and the color wrap is super visual now if you've never used the color out you'll go to shift a hit search and type in color and i'll have the color ramp right here now here's the color i'm going to pop it right here into the base color and um i seem to have clicked on the wrong one so what i'm going to do here i'm going to click the color hit control c or command c if you're on mac control v and then pop that into the base color here so you can see it affected this kind of made it darker and that's because there is black here but that's kind of boring let's do in my opinion the most useful node here and that's going to be the noise now what i'm about to do is show you a string of nodes that makes everything really fun to work with we have the noise texture right here plug the factor into the color ramp now the factor and color are fairly simple to understand factors pure black and white color gives you color so if you plug that into the color if i plug this straight into the base color you'll see the noise texture has some color to it if we just use factor you'll just get black and white so that's useful in some cases now i'm going to use the color ramp here because this gives me some flexibility so if i pull that in it makes things stronger almost adds contrast and makes it really really strong and then i can go ahead and make it lighter too so this is how i can use this which i'll show you with roughness how really nice this ability to do that is and you can change color as well so i'm just going to keep this at white bring it all the way to black now one super important add-on you should always have on so i'm going to edit preferences head on to the add-ons and type in nodewrangler so have this on and why that's important is because you're going to do this every single time ctrl t puts a mapping and a texture coordinate node and this object coordinate is the most important thing you can see how the noise texture is wrapped around it it's just trying to figure out how to map it and it's using pretty much like generated coordinates which is this right here what we want to do is use the object coordinate and what that's going to do is see the data in the object and treat it like an even so now this is actually how the noise texture is supposed to look not that weird circular pattern so now we can do things like this bring up the detail you can bring up the roughness like this so this is rust obviously which is super fun again the noise texture to me is the most useful node i it's super flexible you can use it to control a lot of cool things i'm gonna bring the roughness back and i'm gonna show you one more really interesting thing before we get into other things now this we're going into a little bit more of a complicated um string of things but this is what i do all the time when i'm really trying to do crazy stuff shift a go to search and i'm going to get in a voronoi this is my favorite node it's not the most useful node as this would be like my second favorite this one visually is my favorite because i like sci-fi and organic things and very um straight edge cut things so the voronoi node is great for that now you pop it right here to the texture coordinate and you could see how it sort of took over everything i don't want it to do that the goal of placing my node in between these two things right here which is called the vector line is to distort this guy but okay it's you know it's it's destroying it basically and now it's only a voronoi node going into a noise texture how do we tell it only i only want to affect it a little bit we're going to get another node called a mix rgb now this mix rgb is how you can get two different nodes to speak to each other so sometimes you'd have like a noise texture plugged into here enough and a must grave texture plugged in here you can play with the factor i know that doesn't really describe it but um hopefully that helps you a little bit and i'll show you how this works so i'll plug the mix texture i mean the the mix node here next rgb and then again still nothing happening is just sort of dancing around up to gray the reason why i bring my factor over here and it becomes gray and that's because there's nothing in the socket so it's going to be gray so you can mix these two a little bit um so you can actually kind of make this voronoi node come a little bit like that but that's not the goal of what this next string of nodes i'm adding does what we can do is bring this object coordinate into the color 2 and i'll bring this up so you can kind of see what's going on now these two guys are mixing what's happening here is if i bring the factor all the way to here it's almost as if your own the the object coordinate is strong right strike a little bit i can't speak today it's almost as though this object coordinate is strung straight into the mapping and these don't even exist but if i bring it over here it's as if we had just put that voronoi texture right here on the object coordinate line so what's great about that is you can bring your factor in and do really interesting node combinations that wouldn't otherwise exist doing that and so say i can change this here on the distance we can change it to distance and what that does is if we're just using color it's going to be flat you can see how these are just flat voronoi shapes here so i'll bring the factor over here if you use distance what dis distance does is shows some type of gradient situation so you can see how i mean it's a little bit weirder if i just bring the distance straight to the color ramp here now we're only looking at it you can see how it's kind of um it has some depth to it that's what distance is so let me put this noise texture back here on the color ramp so now we can use distance and go to say like manhattan these are different patterns that we like to use so i'm going to bring that factor in and now we have a very unique noise texture basically so what this whole string of nodes the reason why i did it is now you could kind of use this as a template and you can drop in different textures so say i don't want the i don't want to use the noise texture i want to use magic so i'll get the magic texture plug the vector into the vector and the color into the color and now we have this different kind of look and then i can play with my distortion here and then i can bring the scale down and really do some crazy stuff and now we have a really weird and wild texture going on and you can play with um how everything looks like this is just the magic texture by itself it's a really really cool node and then we bring the factor in and kind of distort it a little bit now we have this really crazy cool texture all right so let's get into other things that i do every time i'm playing with nodes one thing i like to do really love metallic so i'm going to make this a metallic texture we need to pump pop in the bump node so i'll put the bump node right here and we'll put the magic texture straight into the height you have to use height don't use anything else because it won't work and you could play with the strength to do something like that and then say i'm going to make it a little more subtle something like this just kind of a subtle look and then let's play with um texture now sorry roughness so i'm gonna give myself a little bit of space and what i'm gonna do is i'm gonna gonna hit shift and get another color ramp so color ramp and we're going to plug the noise texture into here and we're going to plug the color into the roughness you can have tons of fun with roughness here in blender so if i bring this all the way in it's like a mirror you can see how it's perfectly reflective and then right here you can see it's um not reflecting anything that would be this white portion right here so i can bring this back and we have some reflecting some not so say if i want to make this a little more clear because the black is really strong i can just bring this up like this and you can see a little bit more clearly now how they're interacting and that would that's because all of these things coming through input a black and white image and that's what this color ramp makes sure that it's black and white so anything that's mapped onto here that's the white portion of the color ramp is going to be non-reflective it's going to be rough and then anything black is going to be perfectly reflective and so it's like hey i don't like how it's perfectly reflective it doesn't work for my design doesn't work for my idea so i can take the black portion and bring it up some and now it's still more reflective than this but it's not that perfect mirror and that's really great and it's super useful for metallic textures and things like that when you want to play with roughness and you want to make it look really cool and really nice for example i'll get the musgrave node so musgrave texture i'll plug in the mapping node here to the vector just to keep it even and we'll plug in the musgrave texture to the color ramp so sometimes i'll do this let me pop this down to black sometimes i'll do this is have this have one texture going and then use a different texture for the roughness so they can interact with each other so what i'm going to do is make a really quick roughness i mean a really quick kind of rust i use this in so many tutorials if you follow my tutorials you've probably seen me do this a thousand times dimension down to zero detail all the way up to 16. and now we have this really kind of specky speckled looking thing and then again like i said playing with that roughness gives you a really nice metallic texture so i'll hit the black portion bring it up like this and say bring this down just a little bit because i don't want to be all that now we have a really nice metallic texture so i'll bring this down a little bit more and now we have this really cool metallic texture kind of rusty sometimes i'll bring the scale like 0.5 and play with that and now we have a very unique really cool looking texture that you can use for all kinds of things i'll bring up the depth here on the magic here let me bring it to like five and we have something really cool to play with may bring that strength up on the bump or not but again now we have something super unique you can add to your scenes and whatever you want and everything you saw me do the reason i did the things was for a specific reason and that is again you can almost use this like a template you can apply this basic structure to each material i mean each model and you can just switch out things and play with it and get a billion different variations so there you go that's my sort of mid-tier introduction i know a lot of you been asking me to make a specific video in shading and actually enjoyed making this so thank you guys for watching and i hope you learned something
