 So now that we've had a quick look at what the material editor does in the previous step Now it will do we start using this to actually make our material so you can see here in the middle of our graph We've got our main material node And what I'm going to do is just left click and drag to move that over to the right-hand side And the reason I'm doing it is because all the nodes that will connect will go in here So they never really go off to the right-hand side of it. It all goes to the left So I'm moving that there just to keep things organized and what we're going to use first of all to add color to this material It's called a constant three vector node and what that is is basically it constant means that what the value we give It's going to stay the same three means that there's going to be three values three vectors and Each one of those numbers Represents a color so red green and blue so what we're going to do to add this node is we're going to go in the search Panel of the palette and we're just going to start typing constant And if I have a spot that right put a three in that'll filter out all the others and it'll say constant three vector And you'll see as well It also tells you on the right-hand side that there's a keyboard shortcut for that which will touch on in later steps But for now what I want to do is just drag this from here Into the graph. Oh, there it is Okay, so you'll see that it's zero zero zero that's the three numbers that represent our color and you should also see That the details panel is now updated You can see this is highlighted by the yellow Border and in the details panel we can now see the properties for this and here's the constant this black area here This black rectangle is the swatch for this. So we're going to left-click on that And you get the color picker and what we need to do now is just choose a color So I'm going to choose green so we're going to go for a really sort of simplified grass So we're just going to go over here somewhere And you'll see that even though I've pulled this over into the green The color here that it's going to be still black and the reason for that is this second slide here So this one's gone to green but this one's down here in black, which is really unhelpful So we're going to drag that slider up into green and it'll show you the new color that you're going to have right here So once you're happy with your shade of green Click on okay, and you should notice that this swatch here on your constant three vector node updates and becomes green Okay, so that's good. We've now got this node in here, but it's currently not connected to anything and we need to choose one of these inputs here To connect it to so you can see here. This has an output. That's what this here. It's called an output pin If we left click and drag you can see a wire comes off of it and then it wants us to plop it into one of these But before we do that I just quickly want to talk about what these represent So base color Represents what color you're going to use you've also got a metallic which is when you plug things into that you're telling Unreal whether or not this is a metallic material or not You've also got things like roughness which tells it kind of how rough a surface is and this is part of a PBR Rendering workflow PBR standing for physically based rendering and I will link to a video explaining what PBR is what it means It'll either be one that I found or one of my own. So that'll be up in the top corner Can I point yeah, I'll be in the top corner over there And it'll be down in the description below. So I do recommend checking that out right, so once you've got an understanding of what that's all about what we're going to do is Left click on the output of this and we're going to drop it into the base color and then let go There we go. Right now On yours you should See this turn green But what I've done is I've purposely made it so that mine doesn't just in case yours doesn't as well So, you know what's gone wrong? So what I turned off before I start this video is this button up here in the toolbar called live preview and What that will do is we'll update whenever you make a change You see I've just made a change here, but this didn't update because this is turned off So we'll turn live preview on You can see now this is refreshing and when it's done refreshing it goes green So hopefully yours went green in the first place, but if it ever doesn't make sure you've got live preview turned on and that will update Okay, so that's as far as I want to go with the material so far Don't worry in future steps. This is going to get more complex But just for now what I want to do is save it so you can see just up here But a little asterisk at the end of our material name and that's telling us that this has not yet been saved So we're gonna save it so up here in the toolbar click on save click Okay, it should there we go. It brings up this thing here to tell us what's happening Can take quite a while to save materials. I'm not really sure why There we go. That's now saved so we're done Okay, so the next step will cover how we assign this material to our landscape So I'll see you there for that.
