 In this step, we're going to look at how you add a normal map to a material So before we get started, I'll give you a really simple explanation of what a normal map is What a normal map is used for is when it's on when that material that contains a normal map is on a mesh It controls what will happen when light hits a particular pixel and they can be used to make surfaces look bumpy Or smooth depending on what your desired outcome is In our case, we want this grass to look rougher. So we're going to use the normal map to achieve that So we're going to go back into the material editor here we are and Basically, we're going to use another texture sample node, but this time we're going to put it into the normal input So I'm going to show you a different way to include a texture sample node This is the way that I usually use it's a lot quicker So to do that hold the T key down like so and then left-click somewhere in the material graph There we go, and it just creates one like that So there are a lot of little keyboard shortcuts like that in here and again because I had This texture selected in the level editor. It's made the assumption that I want this one, but I don't so I'll swap it in a minute So I'm just going to ping that into normal First of all and then I'm going to go over here and you can see if you choose the wrong one It makes it look all kinds of wrong. So let's choose the proper one So it's going to be grass underscore n and you see if you're downloading my textures There are two different grasses in there and that's so that you can add some variation But we're just sticking to grass without the number two on it for now. So grass underscore n normal maps generally look purple So keep that in mind and now you can see that this has been updated and it looks nice and rough And that's the result we're going for. So again, we're going to save the material click on the save button And when it's done saving we'll have a look at the effect that that's had and now The grass looks a lot better. It looks a lot more textured. There's there's more to it. So I hope we can zoom in on it a little bit as well as long as you don't get too close It looks pretty cool. So there you go. That's our grass now. So that's really coming along now The big problem with this is that it looks really Tiled you can see this a tile texture and for this practice material that we're making We're not actually going to fix that we'll fix that when we do the proper landscape material a little bit later But for now, I'm pretty happy with this what I'm not happy with though I'm not yet is the organization of this now even though it's a simple material and believe me This is dead simple the one that we've made here. It's a really good habit to get into naming and commenting on everything in here So that's what we're going to cover in the next step how to use comments in the material editor So I'll see you in the next step for that Thanks for watching If you really want to take your learning further than I can cover in this series Then I highly recommend checking out plural site They have loads of really detailed video courses covering game art and game development using Unreal Engine 4 When I learned how to use unreal a couple of years ago This is where I went and I look in regularly to take a new course and improve my skills I recommend checking out the introduction to Unreal Engine 4 course by Joshua Kinney This is really good and offers a good overview of what you can do in unreal You can get a free 10-day trial by using my link in the video description And you get full access to all of their courses for that time at the end of your 10 days You can either subscribe for more or cancel totally up to you.
