Architecture, design, and media professionals all over the world are using Google SketchUp to create detailed 3D models efficiently and quickly. In Google SketchUp 6 Essential Training, design expert George Maestri teaches the foundations of SketchUp's drawing, design, and rendering tools. He covers the fundamentals of the application, the interface, and the Sandbox extension, which is used to create realistic organic shapes and terrain. George also discusses how to model and texture objects from existing photographs and export models to Google Earth to visualize how buildings fit in a real landscape. Exercise files accompany the course.
Now, that we know how to apply materials, let's look at how we can edit those materials to make them more suitable to your scene. So I have got this town house and if we look at it, we will say, Wow! The bricks are little too fine grained. I think those bricks are actually a little small compared to the scale of the house. And we can also tweak other things like color and that sort of thing, and let me show you how to do all of that. We are going to go into Window > Materials and this is essentially the same window we had before. Now, if you notice at the very top of this pull-down, we have an option called In Model and what that is is all the textures that are used in this particular model. Now, let's go ahead and select the brick texture. So I am just going to highlight that and go over to Edit.
Once I do that, I can start changing whatever I want on it. Now, the first tab here is called Color, and what that does is it allows us to tint the texture. So I have a color wheel and a value option here. So I could actually just use this color wheel or this value to brighten and change the hue of the object. If I don't like it, I can always hit this button here, which undoes the color changes and reverses it back to normal. Now, next to this I have two additional buttons. One says match the color of an object in the model. So all I have to do is click on that and I can eyedropper any color I want. So if I wanted to kind of match the stone texture, I could do that, and the other one is called match color on screen. So this will pick up any other color. So for example, if I wanted it to be like the red of this pencil tool here, I can do that and again, this one undoes it.
This next section is called Texture, and this is where it gets the brick texture that it uses. You can see here that it uses a file called Brick_Antique.jpeg to get that brick picture, and if we zoomed in a little bit here, you can see that it's really just an image file. And you can see what that image file looks like in this representation of the texture. Now, this button here says whether or not to use the texture image. Be careful not to click this off. If you click it off, it basically just wipes this box clean, and you would have to use the browser to go ahead and find that file. I don't really want to do that at this point. So don't click that off or else you are going to lose this texture.
Now down here, you have got X and Y dimensions for the texture. Now, what that does is it tells us exactly what size this image file is. So they are telling SketchUp that this particular image file is 4 feet 10 inches this way and 3 feet 1 inches top to bottom. Now, if I wanted to make those bricks bigger, I will have to make that whole picture bigger. So what I can do is just type in some new number, say if I wanted to make it 10 feet, you can see how the bricks instantly pop up to a much bigger size.
Now here, we have a Lock button here which actually locks it to the same proportions as the image file. So for example, if I made that 8 feet, this would go down to 51/4 feet or so, five and one of the quarter. So if I unlock that then I can just make that whatever I want and again what that will do is that will stretch the texture abnormally so it's not exactly as the same aspect ratio as the file. So for example, if I made it 1 foot, it would squish it vertically or if I made it 100 feet, you could see how it stretches it horizontally. So I am going to put that back to 5 feet. Now, we have got some other options here, one is called Colorize and the other option down here is called Opacity. What opacity does is it essentially makes it opaque. So it's a kind of a transparency option here.
Now, one thing you will notice is that when I do transparency on this one that the actual back facing faces have a different material applied. So one of the things you have to realize in SketchUp is that the front and the back of a face can be textured differently, and that's why when I do this as opaque or completely transparent, that is not transparent on the other side because I have another material on the back of these to give it that kind of dark inside texture.
