Subtitles of the Movie (Electric Image Animation System 7 / Texturing / Luminance Channel)
Let's skip over to the Luminance Glow tab. Unlike the Ambient Channel, the Luminance Channel enables you to increase the exposure of the material while maintaining the shading of your material and is not dependent on having an ambient light. Sliding the percentage Slider for Luminance Color brightens the object until it appears luminous. With the Shade button clicked, the luminosity amplifies the diffuse color. With the Color button clicked, you can base the luminosity on another color that's added to the Diffuse color. Now, let's turn on our Grid Texture to the Luminance Maps List and render a Snapshot. You can see the luminance only appears where the white grid exists. Now, I'll turn that off and take our Luminance Slider back to zero and let's talk about Glows. Glows are similar to luminosity in that they take the surface and overexpose it to make it bright and luminous. But a Glow can extend past the surface of the model and create a Glow effect, similar to a light's Glow effect but without illuminating anything else. There are two types of Glow effects and as we see by their Ratio buttons here, you can choose Glow or Glare. Glow can be any arbitrary color while Glare is based on a bright feature of the material, such as a Specular hot spot or a reflection. Setting up a model to glow takes a few steps. First, it's a good idea to set the Amount Slider to 0.5, or half way. This is because you may want to dial the Glow or Glare up or down. Setting the Slider half way allows you to do both. Second, you need to make a Selection Set. As before, go to the Menu Bar, Selection, By Set, Edit Set, and Add a New Set. Call it Glow Ball. Add your model, or sphere in this case, to the set. Third. You need to go to the World Info Window and create a Glow Layer. In the Project Window, double-click the World Object and its Info Window will open. In the Glow tab on the far right Add a Glow Layer, then to its members add the Glow Ball Set. Now you see the two fields at the bottom? Radius is the distance or thickness of the Glow in World Units. And intensity is obvious. Here's a tip: the larger the Radius the dimmer the effect, so if you have a big Glow Radius, you'll probably need to increase the Intensity a bit. Let's set 50 and 2, and render. Now we have a Glare effect which is based around the brightly shaded part of the orange, around the Specular hot spot. Now, let's change it to a Glow effect. We can make the Glow any color. Click on the Swatch and we'll pick blue, and render, and the result is a blue Glow all around the object based on the object's shape instead of its hot spots. Let's turn on the Glow Color Map we have and reset our Glow Color to white, and render. And now our Glow has picked up the colors of our stained glass Color Map. It took a few steps, but what a nice result we have with our Glow.
