Note that a bit of sizing might be
needed to properly place the mask. You can press Shift+h for Size. Press t for Move.
13. When the object is in place, create a keyframe at frame 0 to lock it down. Figure
16.10 shows the mask in place. You might find that a Wireframe view of the scene
helps with aligning the mask.
Figure 16.10 A little bit of positioning in Layout puts the mask object in place.
14. Be sure to save the scene at this point. Don??™t forget that pressing Shift+s saves
incremental versions.
15. Press the F9 key to see how the scene looks. You should see something like Figure
16.11. The mask you made for the planter does indeed block the vase behind it,
but the object is just gray.
Figure 16.11 Rendering a frame shows the mask in place blocking the vase but not really
looking like part of the scene.
Note
16. Open the Surface Editor and select the PlanterMask surface. Then, open the Node
Editor. You??™re going to apply an image map to the mask.
17. Choose 2D Texture and then Image from the Node Editors Add Node drop-down.
This creates an Image node (Figure 16.12).
If your render doesn??™t show any object mask, the polygons might be flipped.
