So here we've made a, kind of plasticky, shiny surface. I'm in Chapter 8_02.c4d if you want to follow along you can open up that as well. Here you can see the material that I've created. What we want to do now is try and make it look more metallic, so I'm going to double-click it to open it up in the material editor. And in here the first thing I am going to do is go back into the, my specular settings just to point out how important the mode is. And its if I go from plastic to metal even with the same shape of specular highlight it gives me a very different result and you'll notice I can still adjust the width and the height and its still has the change an effect on my object.
But it's looking a lot more metallic, you just increase the area of preview here. Also the falloff will effect it as well. Increasing falloff will give us a kind of brighter result. But it tends to clip the values a little bit too much. So, just have a little play with those and come up with what you think is the right setting for your metallic material. Some gotta go for yup, we have got 40 and then may be 80 for the height.
So I just change that to 80 and then with your fall off of 10 and an inner width of 20 so. So it's looking fairly metallic, but a bit too clean. So how can we make it look a little bit more interesting? Well you can add diffusion, so you can adjust the diffusion, if you want to make it darker or lighter, and you can choose whether that effects the specular highlight, or not. We'll come back to diffusion, Let's switch off for now and have a look at some other things.
Luminance we really don't want to add because that illuminates the object. That would be good if you were doing neon lights or something. Transparency we don't really want to add, we don't really want our robot to be transparent. Reflection is something that we probably do want to add because we want metal to be reflective. Now the default value is probably a little bit too much so I'm going to bring it down a little bit so it's less reflective and at the moment it's just reflecting whatever is in the environment with it.
I actually want it to reflect the video layer. Though I'm using an After Effects. Now I already save a J-peg from one of the frames of that. And it's in the text folder which is in the project 8 folder. And it's this one here. Instrumental video 91280 by 720. So I'm going to open that and it loads it as a texture. To reflect onto my object. Now generally I want to increase the blurriness so let's just give it a little bit of bluriness.
We don't want it to be too perfect. In fact we're going to go up to a value of 20 there. And I'm also going to boost the reflective here a little bit higher. So we start to see the metallic surface reflecting this image as well as the other objects in the scene. At any time you can go back to the color and make adjustments to that as well. So if I want to lighten it up a little bit, I can just adjust the color, and that just lightens up the color of the object. Now there's all sorts of other elements that you can add to this.
You could have, add a glow to make it look like a, kind of sci-fi, glowing robot. Which is fantastic. I really like being able to add a glow. And you can choose a color if you deselect used material color. You could choose maybe a kind of sci fi bluey purpley color. Maybe not quite as deep as that. Something like that maybe. Gives them a kind of purple glow and you can adjust the slider. To decide how much of a glow you want to give them. Okay I quite like that.
I quite like having glow to my robots. But we're not going to do that because we're going to add a glow in After Effects. So let's switch that off just now. But what I what you to do is play around with the settings. The ones that you've already applied. So including color diffusion, reflection, and specular So I want you to press pause and go and play with those a little bit, and then come back and press play once you've had a play with the controls. I just want you to experiment, and see what you can come up with, and then I'll show you my settings.
Okay. So I'm presuming you've had a little bit of time to experiment to see what all these things do. Basically, my color settings are 203, 203, 203. I've taken off diffusion. I don't think I need diffusion here. My specular settings, I've adjusted. So I have a metal preset, and then I've adjusted it to a width of 40. Height of 82, no falloff and in a width of 16 and that gives me a nice effect and then just to top it off, I just want to show you what each of these adds.
You'll see that that's what specular adds, it adds that kind of gradation between highlights and shadows if you like. And then I've added on top of that That a reflection, and the reflection, you'll see, just gives us a little bit more definition as well. What I've done with the texture is rather than just applying it using the normal compositing mode, is by applying it using the Add mode, we get a little bit more contrast and a bit more definition. It starts to look more metallic. And I've given that a mix strength of 70.
A brightness of 90, and I've left minimum and maximum samples, and accuracy, at their default settings. Now you'll notice, there is a little bit of greeness in here, but we'll talk about how we can get rid of that, a little bit later. But that gives you a little idea about how you can make a material look more metallic by using reflection and specular. Specular makes it look more shiny Reflection makes it look more reflective. So lets close that and rename it. We can double click the name here and just call it metal ball one.
Okay and that's updated so our main robot has a metallic texture.
