The great thing about 3D is how we can mimic reality and then some. But we are not constrained by natural laws of light and physics. An amazing feature in Electric Image is the ability to be selective about which models our lights illuminate. In this scene we have our two Spheres, both gray now, and the Floor, and the Rim and Fill lights. Well, how do we tell Electric Image what light works in one part of the scene or not. Let's pick the Rim Light. In the Properties tab we see at the bottom Illumination List. This list contains what models we want the light to illuminate or not. With Exclude radio button clicked on anything contained in the list will not be lit by this light. If the Include radio button was clicked on, anything in this list will be lit by the light but nothing else will. Making an illumination list is easy but you can't just add models to it, you have to make a Selection Set. Go up to the Menu Bar and click Select, By Set, Edit Set. A new Window appears. We have two lists. The left side shows our sets of objects. The right side shows the objects within a selected set. Click Add in the Selection Set list and type in a name in the dialog. Let's make it Near Set. Now we have a set but its empty. Go to the Project Window and select the Near Sphere. Back to the Selection Set Window and under the Members List, click Add. Back in the Rim's Light's Properties I'll Add in the Illumination List and choose my Near Set and render a Snapshot. Now the Floor and the far Sphere are lit by the Rim but not the Near Sphere. That's because the Rim's illumination is set to Exclude this set, which contains the Near Sphere. There is also the Fill Light. Let's look at that, and the Fill Light has no Illumination Sets so it continues to light everything. Back to the Rim Light, and let's crank up the Intensity to make this more obvious and render. Now let's change it to Include this set and render. Now only the Near Sphere has this hot rim effect and the rest of the scene goes dark. Let's delete the set from the Illumination List. This does not delete the Selection Set from the scene, however. We can apply this set later. Let's add another light Ð a Spotlight Ð and we'll point it at the Near Sphere. Now let's give it a Gel. This one again, and let's render. We see the Gel hit the Near Sphere and also the Far Sphere in the Floor. Let's say we only want the Gel to appear on the Near Sphere. Click Include. In its Illumination List I'll choose the Near Set and render. And now we see that the Gel only hits the Near Sphere. Of course, you can't achieve this in real life In real life you would add barn doors or flags, or some other global objects to cut off the light from hitting undesired objects. But that basically entails casting shadows everywhere. With an Illumination List EI can restrict what objects the lights interact with. This is a great feature and one I'm sure you'll use over and over.
