Now that we have an overview of how SpotLight works, let’s use it to paint a model.

Follow these steps to add some color texture using SpotLight:

1. Load the DemoHead ZTool. Draw the tool on the canvas and enter Edit mode.
   Change to the Basic Material. Center the head on the screen and add a few subdivision
   levels to support the polypaint detail you are about to apply.


2. From DVD folder \sourceImages_forSpotLightload, load one of the reference photos.
   Click the Add To SpotLight button. Select the photo again, then load the remaining
   photos into SpotLight. With the first photo selected, the whole series will load into the
   SpotLight tool. Click the Tile Unified button to tile the images together on the side of
   the screen.


3. Select the front view image and place it over the head. I use the corner of the eye as a
   guide to line up and scale the image until it is close to the correct size. Place the orange
   circle over the corner of the eye and line the photo up to the model. Scale from this point
   (Figure 5.58). Remember you can use the opacity slider to make it easier to see the model
   through the texture image.


4. Turn Opacity down so the image is barely visible. Dial up the Fade control so the SpotLight
   will feather when you enter Projection mode. With the opacity down you can see the effect
   this will have. This control will project a “spotlight” of texture with your brush as you
   paint. This is how SpotLight got its name (Figure 5.59).


5. You are now ready to enter Projection mode. Press the Z hotkey and you will see your
   brush now projects a circle of texture based on the image you just placed (Figure 5.60).
   Select the Standard brush and make sure that only RGB is activated on the brush—ZAdd
   and M should be off. Select the DragRect stroke. Click and drag from the center of the
   head and you will see the texture reference apply as polypaint data.


6. This applies an overall texture to the face. We will now zoom in for more detail. Center
   the eye on screen and press Z to exit SpotLight. Using the same techniques as before, scale
   the eye texture source to line up with the eye of the model. Press Z to enter Projection
   mode. Change the stroke to Freehand and brush around the eye area. Repeat this process
   for the mouth.
