Lesson 15 Review for Motion 4 Book
Show Answers:

  1. 1. How can you automatically switch all groups in your project to 3D?
    By adding a camera.
  2. 2. Name three locations in which you can change the position and rotation of a layer or group in 3D space.
    In the Inspector, the HUD, or the Canvas.
  3. 3. What's the difference between layers in a 2D group and in a 3D group?
    Layers in 2D groups are not affected by the camera, and are composited based on stacking order in the Layers tab.
  4. 4. Do the 3D View tools always control the camera?
    No. The 3D View tools control the camera only when the window is set to a Camera view.
  5. 5. Which tool is used to make 3D transformations directly in the Canvas, and which keyboard shortcut selects it?
    The Adjust 3D Transform tool allows you to transform the position and rotation of layers and groups in both the HUD and the Canvas. Press Q to select the Adjust 3D Transform tool.
  6. 6. How can you quickly move a camera to look at and frame a specific layer in 3D space?
    Select the layer, and from the Camera menu, choose Frame Object, or press Command-F.
  7. 7. In the HUD, how would you set the Adjust Around pop up menu if you wanted the z-axis of a layer to always point straight at you, no matter how the layer or the camera was oriented?
    Set the Adjust Around pop-up menu to View Axis mode to orient the axes so that they reflect the orientation of your computer screen.
  8. 8. You have two layers in different locations and rotations in 3D space. You add an image mask to each layer, and you apply the same source layer to both image masks. One layer is masked and one is not. How can you make it mask both layers?
    The image mask uses the location and rotation of the source layer to mask the target layer. So you need separate copies of each image mask source, each aligned to the layer you are masking.
