Blender is a powerful open-source tool for 2D and 3D graphics, full-on animation, compositing, and post-production. It is used to create movies and special effects, even in HD. In Blender Essential Training, Roger Wickes offers new Blender users a thorough explanation of its interface, tools, and features. He also demonstrates practical techniques and shows how to access the online and openndash;content resources of this amazing tool. Specific 3D techniques covered include navigating in 3D space, using cameras and lights, and rendering. Roger demonstrates how to rig, animate, and composite a character over live action. Exercise files accompany the course.
The first step to a convincing surface is a base color and some kind of material that gives it a feeling of depth and substance. The purpose of this video is to go over all of the basic material settings and the basic options that you have. First of all, we've Captain Knowledge and he is one mesh but he has many different colors assigned to him. So that's the first thing you need to know is that each mesh can have many different materials. To see what those materials are, we come over here to the Link and Materials settings under the Editing Context and over here we see the different materials that make up and are used to color Captain Knowledge.
If we tab into Edit Mode and we select the face, we can see that Blender shows us the material that is assigned to that particular face. So we've his face here and we've that his lips are assigned to the wrong color. So if we go ahead and Shift+Select those three faces that have the wrong color and then Shift+Select one that does have the right color and then come over here and click Assign. We have now changed the assignment of those faces to be this flesh color. So now his lips are split and thinner on top.
But what defines this flesh color? Well, that's under here under Shading and Material buttons. We've a whole bunch of different panels that have a ton of different options for setting up the basic materials. Here in the Material panel, we've a couple of different options. One is to mark a material Shadeless or what's called Self Illuminating inside Max and we often do that when we're using a picture of a real world place. The No Mist setting here excludes this material from that mist that we've talked about in the world settings.
And here is where you set the basic base color of the mesh. So when we click on Color here, now these sliders are updated to reflect the RGB values of this actual color over here. A very important but often overlooked slider down here is A, simply marked A which is the Alpha Channel of any color and you use this to make an object semitransparent or completely transparent or when it's at 1, completely opaque. Now there are three colors that we set here, the base color.
The specular color is when you look at something and it has a shine to it. What color is that shine? That's called the specular color. And then if it reflects something back at you when you look like in a mirror, you usually reflect back the perfect light to reflect the perfect color. But you can have colored mirrors as well. These little balls that are in the yard sometimes that you see in Arizona and like that. They are often colored blue or green or something like that and you can set the mirror color here as well. Now any of these colors, the color, the base color, which is called the diffuse color and the specular color, they don't have to be a single color.
You can use the Color Ramps here and expand this panel to show you that if you enable color bands for the diffuse color, now instead of just being this one color, the diffuse color will be a range of colors and this range is based on some input. You could use the amount of Energy that the material is getting based on the light source. And then mix that according to some factor into the base color to provide a better range of colors. So that's the basic diffuse setting and the basic material options that you have for setting up the basic color inside Blender.
