Join Andy Needham for an in-depth discussion in this video Manipulate materials on objects, part of Cinema 4D R20 Essential Training: Motion Graphics.
- [Instructor] Taking the scene where we created the transparent materials. We did that in a previous movie. We're going to apply a label material to the label geometry. So what we need to do is we have a label material already set up and you can come in and take a look at this in your own time. We apply it to our label geometry and nothing happens if we show our interactive render region ALT R. Yes, we can see it in the renderer, but it's a bit confusing not being able to see it in the viewport, so why is that? If you come over to the basic tab, it's because we are using a color, and it's overriding the material. So, if we just turn that to off, now we'll be able to see our material and we can start to work with it here. Now, it's not facing us which is a problem. A couple of ways of solving this would be to first, maybe rotate the object, so if we rotate that around about 90 degrees, that solves the issue. But what if you can't rotate? Well, we can change the projection to something a bit more meaningful to this type of object, something like cylindrical, but that stretches our material and it doesn't solve the problem that we have. So for that we need to change the offset values and so we can start to manipulate this and adjust it to where we feel it's starting to fit. And then of course changing the length, something like 64 seems to work, and then of course, we're still not facing us, so we need to come in and change the heading rotation, something like 89, 90 is just about fine. And now when we render, that's looking good. Now, it might be less intuitive to manipulate the numbers here, and so we can use another mode for that. In this example, we want to put some foam on the top of this coffee cup. And we're just adding a bit more to this. It looks a little bit flat at the moment. So, we crop our foam texture and we'll drop it on top of the coffee, and it's not mapping correctly. So, I want to use a different projection mode for this. I'll try cubic and although that is looking better, I feel like the scale of this isn't quite right. So this is where the texture mode comes into play. So I'll click on that and if I go into on my orthographic views, I can see a box around my object. Now this is the cubic projection. You can see it is in fact a cube, if we look in the perspective view. But it's easy to manipulate it in this view, 'cause I know I want to encompass the top of the coffee cup. So if I press two on the keyboard, I can start to scale this as if it were an object, and so I can scale this down, like so, and if I just come back to the view that I had before. For me that's looking a lot better and I can, of course, come into the coordinates and refine it further. If I want it to be slightly smaller, I can dial in that as I please. So that was a look at how we manipulate materials and objects. Remember you can change the projection from UVW to another mode which suits the object you're working on, and then by modifying the UV properties and coordinates of the material tag, you can achieve a better looking result.
