20. Now all you need to do is hook the Image node into the destination node to apply
it to the PlanterMask. Drag the Color output of the Image node to the Color
input of the destination node, as shown in Figure 16.14.
Figure 16.14 The Image node is hooked into the Color input of the destination node.
In most cases, you??™ll need to adjust the Luminosity and Diffuse values for the
front projection??“mapped surface. Because of the lighting in the scene, you need
to carefully balance these two values so that the polygons that make up the mask
perfectly blend and match the background image. In this particular tutorial, the
mask is small, so making it blend is not too difficult.
Note
21. To make the mask blend a bit better, close the Node Editor. Then, back in the
Surface Editor, set Luminosity to 40% and Diffuse to 70%. Render a frame again
(press F9), and you??™ll see that the front projection mask is easier to see, but the
lighting needs to change.
Remember to move, rotate, size, and stretch the mask object. Render a frame. It will
always show a portion of the image, no matter where you place it or what its angle is.
