 In this step, we're going to improve the look of the material that we've created by manipulating the roughness value So as I said in the previous video The problem with the material as it stands is that it's too shiny And so what we're gonna do is we're gonna dial up the roughness And that's gonna make this look better. So in order to do that We need to move back into our practice material. So here's mine here So I'm just gonna double-click to make sure it's open And I don't think I showed you this in the previous step But I like to do especially when I'm working between the material editor and the level editor is you can grab any one of these tabs up Here and you can tear it away and then you can dock it again. So that will dock it next to The the level editor which can make it a little bit easier to work with so we're going to go back into the material editor And we're going to add a roughness value to this material. So you can see There is a roughness input just here, but we've got nothing going in there at the moment Before we put something in there I'm just going to give you a quick explanation of how roughness works in on-mail engine So it works on a scale from zero to one with zero being very shiny and One being really rough. So What we need to do is get a number and plug it into that So this time what we'll do is we're going to right click somewhere in the graph here I'm going to start typing const and we want the one we're looking for is called constant So I'll give that a little clickety-click There it is and then I think I'll just place that here. I'm going to plug that straight into The roughness so that's already connected up now, but we need to give it a value so as it stands it's set to zero which means that the Material will be exactly the same as what was before we did this So over here in the details panel we need to put a value in so we need to state what this number is going to be and The number can be anything if I wanted to set it to 17 I code, but That wouldn't have much of an effect because roughness only goes up to one So I know that I do want it to be much rougher You can see up here this little highlight there showing that it's quite shiny So I'm going to set it to about 0.75 so about 75% off would be a way of looking at that. I'll press enter You'll see now that this should update and now that highlights gone It's a much rougher material. So to see the effect that this has on the landscape. We need to save it And I'm just wait for that to happen. Oh There we go Come on Yeah, there we go, right and then we'll go back into The level and you can see it just updated there as I flicked over and now this looks much better So these highlights there's still a little bit of shininess to it as there should be actually if you look at Um a hillside with grass on it and grass is actually quite a shiny thing to look at So this there should be something there But not to the degree that we had it previously Right, so that wraps up this step. We've managed to get some roughness into the material and it's starting to look better But it still looks flat green Which if you're going for that style would be okay, but we want it to look a little bit more realistic So in the next step we're going to start looking at digital textures So like a digital image and bring that in instead of the flat color that we've got and that will make it start Looking much nicer.
