In this lesson, I'm gonna show you the basics of material and texturing using Arnold in Maya 2022. Okay, we'll start with a new file. Oh, okay. First thing I wanna do is just add a plane and let's just increase that. Okay, I'm just going to turn off my grid here and then I'm just going to add some primitive shapes. So I'm gonna add this and I'll duplicate that. So add a couple of these. Control + D to duplicate and just putting some around here, maybe add a Torus. Okay, maybe a couple of those. Control duplicate. Now if you're gonna add a box you're gonna wanna make sure that you have locking loops. So if you just create this here don't just leave it like this because you won't get good reflections on the corners. So you'll want to make sure that you add your loops. So remember three on either side. So there's one there, there's one there there's one there, there's one there, and there's there. Oops, there. And I think that's it, one more here, like that. And right click and press three. Okay, that looks good. Gonna make this a little bit larger, and I'll add a few. Add another one Control + D to duplicate and just arrange them. Okay, so if we go into our renderer and go into Arnold it's gonna be, if I hit play it's gonna be completely black because we don't have any lights in here yet. So let's go back out here, go back to the Viewport. And anywhere on whichever modeling rigging you always have Arnold over here. So we're gonna go to Arnold, Lights and we'll add a Skydome light. Now what we wanna do is we wanna add a HCRI lighting. Now a HCRI lighting will help you get more realistic reflections, and we're gonna add one here. So when you click on here, go to your AI dome light here. And above intensity is a color. There's a little map right here. Click on that and then we're gonna click on File. Then you're gonna go to your image and you're gonna browse. And I provided this file and it's here, this one here and you can see what this is. So this is how our scene is gonna be lit and the reflections will be the reflections off of this room. And this reflection is pretty much black and white so I'm getting more neutral colors here. So if it was an outside, it would be a lot of blue. And you can really change the HCRI file will drastically change the reflections, click open. And it's in this room. Now you can take this here and rotate it around to get different reflections. Now when we go to Render, Arnold now we're getting this here. Now this room, doesn't have a lot of strong, like a real direct light source. So the reflections are kind of soft here and I kind of picked that for a reason just so we're not getting these really hard shadows. All right, the next thing we're gonna do is, we're gonna select each object here and we're gonna assign a new material. So I'm not gonna, okay I'll just do this a couple times here. What you'll do is you'll click on here down at the bottom right clicking, I'm right clicking going down to assign new material. Then with this, I'm gonna go to Arnold Shader and I'm gonna go to AI Standard. I'm gonna do this for each one of these objects. So assign new material, shader, okay? AI standard surface. Okay, so I added the AI standard surface to all the objects in the scene. And the first thing I wanna show you is you can actually do the presets. So if you click on here, and first of all, on this one here I have a lot of information. I'm gonna go to edit, delete by type history, okay? And then there's the standard shader. We have presets right here. So if we wanted to see, let's do clay, and we'll do replace. The replace is if you wanted it to add like if I wanted do half of something. So if I wanted to have half of that, and then go to another preset, and let's do half, so it's clay but also a preset, and let's give it a little chrome and then let's blend it maybe at 25%, something like that. So it kind of goes in be, you can mix and match between presets and we'll click on another one here. Standard surface presets. Let's do chrome. Replace nice chrome. Another one that's kind of cool is gold. So here, presets, gold. And you can see if I rotate this skydome it really kind of changes the render and how the reflections work because the reflections are working off the environment or the HCRI file. Okay, so let's manually build some of these. All right, so first of all when you click on here, go to surface shader here. First one obviously is the color. So if you can just, if you wanna change the base color here you can do that here. And just doing that alone it gives you kind of a good shader here. But if we wanna have more reflectivity, like a car paint you can do that here, let's click back on here go to surface and come down here to coat. And the weight is the amount. So if you come in here and bring that all the way up you can see that it's rarely getting a lot more reflections once it renders. Now, if you want to turn the skydome off what you do is select on it, go to the attribute editor and under the light shape, turn your camera to zero, okay? Nothing happens yet. And then come down here to the Viewport and turn your sky radius to zero and that will get rid of that. If you don't want that, if you wanna do glass what you'll do is select the shader and turn the base color, make it black. All the way black. Then under transmission, turn that to 100% like this. And now we have a glass reflection. You can also change the the ICR. So glass is about 150, water is about 135 and that just changes the reflection properties. Also with glass, when you click on it you want to make sure the roughness turn, the roughness and speculator, turn that all the way off. For metallic, that's another simple one to do. All you have to do is in the base, the metalness bring that all the way up like that. Then if you want it, super, let's give that a color, a base color change it to sort of a chrome color and let's take the roughness all the way out too and now look at that. It's almost like a chrome here. So the roughness, if you bring that up a little bit, it kind of changes, so it's not quite so reflective. The last one I'm gonna show you is illumination. So if you wanna have a glow effect, for this let's select the skydome and come up here in the sky dome shape. And let's bring the intensity down. Let's bring it down to about one. So that's kind of turning off the lights here. Then we'll select this here go to the standard surface shader and let's go down here to admission. I'm gonna give it a color, maybe a warm color. Let's do, let's try blue. A cool color. Let's try something like this. Okay, nothing's happened yet, but as soon as we bump this up to maybe two, you can see here what it's doing. It's actually throwing light on other surfaces. In the next video, I'm gonna show you Maya's hyper shade. Thanks for watching.
