 Hello, hello, welcome to a new video. So as you may be able to see we are back with the cabin project I said I would be back with some bonus steps, and I am going to deliver So we're just going to just jump straight into it. I think let's not mess about what we're going for is this so Hopefully you can see but there is a nice subtle little flickering effect going on with that window if we're just moving a little bit closer You should be able to see that that's happening so you can see that it's just looking like there's a light behind that That's flickering and it looks beautiful even if I say so myself So in this first part of the bonus steps, we're going to get this working So you can see I've already made like an example What I'll do is I'll go back to the original shader So I'll just swap that one back in and that's what we had originally So we need to get that flickering effect going on so let's just close that one We need to open the window material So this is what we left off with when we made the window material originally And what we're going to do now is just take these two nodes out here because these are the ones going into the emissive color We're going to bring them out because we're going to do a little bit more playing with them So there it is So at the moment I'm fairly happy with this part here This is doing what I need it to do we have an emissive color and it's being multiplied But what we want to do is get something to change How strong that's happening how strong the multiplication of that value is and so to do that we're going to bring in a Normal map actually and we're going to pan that and you'll see how it always very clever. So first thing I'm going to do I stick in a multiplier node here There it is lovely lovely and we're going to ping this into a And well, we'll connect it all up at the end Into be we need to do some Cleverness so we'll get from be and we're going to do a texture sample Where is it? There it is and what I want is a normal map So if we go into here, and I'm going to go for burnt wood just because when I tried it I liked that one the best so this is what it gives us we can see the normal map there And what I want to do is get that moving so that we can have the values changing that makes them to the minute So into the UV's we're going to place a panor and the job of this node is to just move Textures in kind of the X axis or the the Y axis So I'll just pull that out and What we'll do just to get this moving we're going to just if we do one By one just so you can see how that works and That will pan this but at the moment We're not going to see anything because I don't have live nodes and live updates turned on so we'll turn that on Well, both of those on and then as this updates you will see That this moves there it goes so you can see that that is now panning that texture across the the texture space But this won't work at the moment because it's just not strong enough So what we're going to do is make that look a little bit bigger so into this panor we're going to add a Texture Coordinate node if I can spell it right texture Coordinate lovely and Then we're going to zoom right in on this texture And the value we're going to use or the values we're going to use on the tiling are 0.0001 so we're making it very small which makes it really zoom in and the same money of the ones so 0.0001 and when I press enter you'll see just here when this updates That what it instead of you seeing the whole texture panning across It's just gonna look like the blue values are going up and down which is exactly what we want It's a lot like okay, so there it is and you can see that that is now going kind of crazy Which might be what you're going for but I want it to be a little bit more subtle than that So in order to change that we're going to go into our panor and instead of having a speed of one Which is far too much. We're going to have 0.001 I believe 0.001 and Then we'll let that update and was should see a more gradual changing of the blue values Okay, so that's now updating and I can see that the blue values are changing But I don't think they're really changing quickly enough for me So I'm going to experiment with the numbers until I find something I like Okay, so with a bit of experimentation I've put in values of 0.007 into the speed x and the speed y and I'm happier with the way that these values are changing. I think that's going to look quite good when we put it all together Okay, so I want to do now we can see that this is all going into here And I want to see how that's going to look and I'll give you a hint It's gonna look wrong, but I'll explain why so what I'm going to do is go to this multiply node and I'm going to start previewing that node which should Put that value up here and you can see what's happening is that instead of just raising or lowering The intensity of that emissive value. It's just mixing the colors. So we're getting reds blues greens It doesn't look very good. I don't like it So the reason for that is because we're mixing all three channels and all we want is are the values from the blue channel So instead of going from this value here this output We're going to go to the blue one and put that in B instead and then when that updates and we see up here What you should see is that we just starting to get that flickering effect So the strength of it may not be right yet But the effect is actually happening. So what we'll do now is just stop previewing this and We're going to put this now into the emissive color to replace what we had connected before and This will then show us What it's going to look like as a finished material Okay, so we can now see that that's happening But we need to go into the level and see how well that's happening if it's something that we want or if we need to tweak it a Little bit So let's save that and then we'll go out into the level and see what it looks like Okay, so I'm just gonna dock this window up here Zoom out a little bit to see if this effect is strong enough It's actually not bad. I might want to just dial it up a little bit, but overall I'm quite happy That's not a bad a bad outcome really is it so I think what I'm going to do Is this multiply here? I'm actually going to tone this down Because I don't want it to be really bright all the time. So I'm gonna bring this down to about five and That means that now this emissive effects not gonna be very strong at all But we're going to supercharge this side of the equation here So I'm gonna put in a new multiply multiply and So the result of that's going to go into B and Our blue value is going to go into a of this new multiply and then what we're going to do is Multiply this by about 12 and I might come back and change this value. We'll go with 12 for now And then we'll see how that comes out Okay, so it's definitely doing something. Let's go save it back out to the level and see if we prefer this outcome to the previous one I Do so I think what it's done now is it's made it brighter overall and that means up here We can see that that value is dropping up and down which gives the effect Hopefully that there's some kind of fire burning in there and that will work with that the smoke coming out of the chimney So that brings us to the end of this first step. It's very exciting getting back into this project So there are Two maybe three more of these steps that we'll do and then I'm going to leave this Cabin project alone and we'll move on to something completely different which will be exciting So thanks for sticking with me for this one and I will see you very soon for another one Bizes 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. It's got to be worth a free trial though, right? I'd like to say a massive.
