If we come down to roughness, I need to also load up a roughness map, so I will do so right now. So, this is what we need to just go ahead and work with texture maps. Octane is going to be able to take care of this for us. We don't have to gamma-correct this since this is an SRGB image. So your corresponding image format can be used for transparency. The alpha type is used when you have RGB and an alpha channel included. Just because we want to use gray scale values, we don't really care about RGB as much, we just want use those black and white values and work on the float. Float is going to be for like our roughness maybe our specular and our bump maps are going to be float. Normal type is going to be RGB, so we're going to load up any RGB maps with this Normal type. So, down here, just for the type, we're going to have it set to Normal. We have dirt, wear, things like that that are going to help it make it look a lot better. As just a general note, adding variation to your texture maps inside of your diffuse, is going to give you a little bit more realism just because surfaces in the real world are not perfect and we don't have the same color going across an object. Okay, so, what I have here is just kind of my base color in the diffuse and this is going to be the overall color and we also have some variation across the surface, so that we have some different details in other places. It would just take a little bit too long to do that in all one series. Unfortunately, we won't be going into Substance Designer in this course. So as an overview, I just would like to talk about what makes this texture map so important to this chair asset. And all theses textures that I'm going to be loading up have been created inside a Substance Designer. So I'm going to go to C4D Octane, and image texture, and I'm going to navigate to that texture. So, what I'm going to do is I have a texture map that I'm going to load in. And that's going to allow us to have a nice, shiny reflection if we need to or you can increase the roughness to make it irregular. Glossy is going to be the one that we're going to focus on. So, this is something like a clay vase maybe, or sand, something that's incredibly diffuse. Just as an overview, diffuse is something that has incredible irregularities on the surface, and we don't really see the reflection so much on the surface. And the material type that we're going to be using from these different models is the glossy type. Okay, so let's go ahead and create a shader, octane material. And the great thing about PBR Rendering is that if it looks really good in this scene, it's going to look great with our other objects in our other scene. So, this allows me to just focus on one material type, and make that look as good as possible. And I have a camera in here as well, which is set up almost the exact same way as the last scene.
We're just going to focus on the chair and making this look as good as possible. And if we come into this other scene that I have, we can see that we just have the actual mesh inside of a room, and this is basically the same lighting setup. So, that's what we're going to focus on, is this blue chair. Dielectrics are essentially anything that is not a conductor, anything that exhibits some traits like may be the bricks on a fireplace, we have the shiny hardwood floors and then we also have this kind of faux leather that's going to be on this chair right here.
OCTANE RENDER MATERIAL HOW TO
In these next two videos, we're going to be talking about how to create dielectrics and conductors inside of Cinema 4D in Octane So, in this first video, we're just going to be talking about dielectrics.
