All right now that we've taken a look at the basics of Blender and we've created our first animation
Let's go a.
Let's go to level two.
Let's take a look at some more complex things and what we're going to start with is the node Ed..
So what is the node editor and how do we use it and what does it do.
Well first of all let's go ahead and make sure that we're in cycles render.
And now we're going to delete our default cube and hitting T on the keyboard to close our tool shelf.
Let's go ahead and split the screens by going here the bottom left splitting the screen and changing
this one from the 3D view to the node editor and hitting and on our keyboard to close that.
So right here you see that nothing is displayed because we don't have an object or a material assigned
to any object.
So what is the node Ed..
Well I'm going to show you exactly what it is and what it does.
If we hit shift day at Ammash and add a plane let's go ahead and scale this up and bring it up above
the floor.
And this is going to be our second project so make sure that you save as we go because we're going to
be using this scene from one Tauriel to the next and building upon it and learning some pretty cool
things.
Now go into the material tab over here.
Let's go ahead and click new and you will see right away in a note editor what happens.
So you can see that it's added what are called nodes.
Right here we have the diffuse node which is the same as what we have right here.
And we have the material output node.
So let's rename this material very fast to would underscore floor.
And now the node Ed. is basically a way to manipulate and add more interesting details and things to
our materials we could add glares we could add contrast brightness.
We could composite it's basically a compositor that will add or change the effect of a lot of your scenes.
It's a really awesome tool and thing to be using.
It might look overwhelming at first but trust me it is very very useful.
Now again the compositor right here.
Let's go over a little bit of the different buttons and things that we have in this composite scene
so you can see that right now we are on the object tab and the material hence the object that we have
selected and the material so we're on the material nodes or composite or of the object.
Now as you can see right here it's basically displaying exactly what we have here.
As I said a diffuse node which is right here to move any node.
All you have to do is hit G on the keyboard to move it and you could right click to select the same
thing as an object mode.
You can hit the x key to delete a node and control Z to undo that.
Now again nodes are really cool because way allows for you to do of course if we were to just set up
a simple scene with just a plain and a diffused material we wouldn't need to use the notes editor to
do that.
Now as you can see if I delete this diffuse node by selecting it and heading X we now don't have a diffused
node to our material now we could go here and select the fuse or we could hit shift day and add in a
shader and it's like diffuse and then connected by left click and dragging it to the surface output
right here are the surface input and you could see that it reflects that change over here.
So again if you were to use just a simple plane with the diffused or with a diffuse shader you would
not need the note editor to go in here and do that.
You could just add it through here.
But when you start to add a lot of things such as secularity and a glare and some contrast and some
color saturation and all this other foot you know all these other editing or extra compositing on top
you would definitely need a note editor because it will be displayed here and you could sometimes they
get you have over 50 or 100 nodes here you can have just for one single thing and having that here would
be way overwhelming so the note editor is awesome for that.
Let's take a look at a couple other things.
So again shift a gives you a menu to add different things you can see that all the shaders that we had
over there to the right on here as well we could add like that converters we could add all kinds of
things colors you know wheels brightness contrast and all kinds of different things to change the way
our material looks and add more realism and more detail to it.
Let's actually go ahead and do something right now to show you exactly what I mean.
Let's go ahead and add that texture that we had and for our offense.
But on this floor right here as we are going to be needing a wood floor for our next project anyways.
Now I could go here like I did before and go to image texture and select it from there.
But let's do it from the note editor.
So go ahead and hit shift day.
Or you also have the menu down here.
But let's go ahead and hit shift day add shader or actually add input and we're going to add a nodes
under color texture.
There we go.
I came and find the menu myself under texture we had image texture.
Now collect connect the color of the image texture to the color of the diffuse.
Now you can see that added it here as well.
All we have to do now is go to open and find our image texture.
And open that image texture and now you can see that we have it loaded here and that is awesome.
If we go over here to the rendered viewport mode you can see that nothing's happening because we haven't
unwrapped our plane yet.
So if I go hit 7 to go into top view go down here and go to Edit mode.
And let me actually go to solid hit you and unwrap this.
And if we go to the U-V image editor just to show you what just happened you can see that unwrapped
right here as well and just go down here and select your image texture that we have here so you can
see exactly how it looks.
Now going back to object mode and two rendered mode you can see that our texture is on our plane and
if we go to the node editor you can see that it's here as well and it's displayed here as well.
Just like it would if we had selected it from here.
Now that is awesome because now what we're going to do with the node out there.
Let's get a little fancier because with our fence we had added just a plain image texture and that's
great.
But let's do something really cool with the note editor and adding more detail and that's going to be
called a bump map.
So wait until you see what a bump map does.
I think you're going to be super excited when you realize how much detail you can get with just adding
a couple of tweaks in the node Ed..
All right I'll see you in the next tutorial.
Take care.
See you then.
All right here's our little quote for the end of this tutorial.
Don't be so scared of making a mistake that you make the mistake of not living at all.
One shouldn't see mistakes as a step backwards but rather as a stepping stone to your fullest potential.
So take a step forward and let those mistakes propel you to greater heights.
Previously not imagined.
All right.
Don't be afraid of mistakes.
Go for it.
You guys see in the next tutorial.
