Introduction

This tutorial guides you through the process of navigating the interface and manipulating views in the Viewer window.



The major steps of this tutorial are as follows:

Preparing the Scene

Selecting Views

Manipulating the Cameras

Splitting the Viewer Window



Note:

This tutorial does not explain how to perform basic functions such as opening scenes, saving scenes, and playing takes.

Step 1: Preparing the Scene

In this step, you will add a favorite path for the tutorial folder in the Asset browser window. As a result, you will be able to access the tutorial files directly from the interface.



1. From the menu bar, select File>New, then select Layout>Editing.



MotionBuilder displays a new scene using the Editing layout. This layout displays all the windows you need for your work in this tutorial.



2. Right-click in the Asset browser and select Add favorite path from the contextual menu (fig 4-1).

3. In the Open directory dialog box that appears, choose the Viewer folder (created when unzipping the T04_Viewer.zip file) and click OK.



The Viewer folder is added as a favorite path in the Asset browser (fig 4-2, A).

4. In the Asset browser, drag the Kicks_fbx.zip file from the Viewer folder in the Asset browser into the Viewer window.



5. Select FBX Open>Kicks (fig 4-3, B).

A Character named Surfer appears in the Viewer window (fig 4-4).

Step 2: Selecting Views

In this step, you will change how you view the elements in your scene.



1. Click the First Frame button (fig 4-5, A), or press Ctrl-Home to go to the first frame of the take.

2. Click Play in the Transport Controls to play the take (fig 4-5, B).



3. In the top left corner of the Viewer window, click Display (fig 4-6, B).

4. The Display menu appears. Select Normal (fig 4-7).

The models and all other elements in your scene become visible, except for elements that are inside the models (fig 4-8, A). For example, in fig 4-8, A, joints and bones that extend outside the model are visible on the Character s hands and head.



5. In the Display menu, select X-Ray.



In X-Ray mode, elements are visible, whether they are inside or outside the model (fig 4-8, B).



Note:

When in X-Ray viewing mode, you cannot select models.



6. In the Display menu, select Models Only.



Only the models are now visible in the scene. All other elements such as nulls, markers, and skeletons are hidden (fig 4-8, C).

Note:

You can also use the keyboard shortcut Ctrl-A to switch between the three display modes.

Step 3: Manipulating the Cameras

In this step, you will manipulate the cameras in your scene and try out the shortcuts for various camera movements.



1. In the top left corner of the Viewer window, click View. The View menu displays (fig 4-9).

2. Select Perspective>Producer Perspective.



The Producer Perspective camera displays the scene with the XZ plane defining the horizon. The Z-axis faces the camera and continues toward the horizon, the X-axis is left and right, and the Y-axis is up and down.



You can translate or move an object on all three planes with this camera view. This view also lets you zoom, pan, and orbit the camera.



3. Click in the Viewer window, and try out each of the following manipulations:



Dolly (Ctrl-Drag): Moves the camera towards or away from the Camera Interest.



Follow (Ctrl-Right--Drag): Moves both the camera and Camera Interest along the plane viewed by the camera



.Orbit (Shift-Ctrl-Drag): Moves the camera around the Camera Interest. This changes the location of the camera in the scene. This option is only available with the Producer Perspective camera.



p>Pan/Tilt (Shift-Ctrl-Right-Drag): Moves the Camera Interest around the camera. This changes the rotation of the camera and the position of the Camera Interest. This option is only available with the Producer Perspective camera.

Slide (Shift-Right-Drag): Moves the camera following an ellipse. The Camera Interest is the summit of the ellipse.



Track (Shift-Drag): Moves the camera and its interest left and right or up and down. This changes the location of the camera and the Camera Interest in the scene.



Track (Shift-Drag): Moves the camera and its interest left and right or up and down. This changes the location of the camera and the Camera Interest in the scene.



Zoom (Z-Drag): This changes the camera's angle of view. The aperture is shown in the bottom left corner of the Viewer window. This option is only available with the Producer Perspective and Producer Top camera views.



Note:

Make sure your mouse pointer is in the Viewer window when using the shortcut.



You can also change the size of the Viewer window by dragging the edges of the pane.

Step 4: Splitting the Viewer Window

In this step, you will investigate the different views and cameras available in MotionBuilder while working in the Viewer window.



1. In the top left corner of the Viewer window, select View>Panes.



The Panes menu appears (fig 4-10) with four options for dividing the Viewer window into multiple views. These smaller views make it possible to view a scene using several cameras simultaneously.

2. Select the 3 option. MotionBuilder divides the Viewer window into three views (fig 4-11).



You can also press Ctrl-2, Ctrl-3, or Ctrl-4 to obtain two, three, or four different views. Ctrl-1 returns you to a single view.

3. Click inside each of the new views.



A white outline surrounds each view you click, indicating that it is now the active view. Selecting an element in a view also automatically changes that view to the current view.



Note:

You must activate a view before you can perform an action in it.



4. Activate the top right view in the Viewer window, then select Orthographic from the View menu.



The Orthographic menu appears (fig 4-12), displaying options for viewing your scene from various perspectives.

5. Select Producer Top.



The view switches to the Producer Top perspective (fig 4-13, B). The scene displays with the XZ plane defining the grid. The X-axis is left and right, and the Z-axis is up and down. The Y-axis points towards the camera. This view lets you translate an object along the X and Z planes. You can zoom and pan the camera, but not orbit.



6. Activate the bottom pane of the Viewer window, then press Ctrl-W to switch to Schematic view.



The Schematic view displays the scene as a hierarchy (fig 4-13, C). This perspective is helpful when you want to select specific objects or reference points in your scene.



If the Schematic view seems empty when you open it, press A to Frame everything in the view.



Note:

In the Schematic pane, you can also Z-drag to zoom in on a specific area, Ctrl-drag up and down to zoom in and out, and Shift-drag to pan.



After you have opened these views and camera angles, the interface should look similar to fig 4-13.

7. Using the View menu and the shortcuts described in the Interface guide, try out the other view options available.

Conclusion

During this tutorial, you manipulated the views of models and elements in your scene. You switched to different Viewer panes and made use of several camera views.



Once you know how to navigate the interface and change the views, you can manipulate objects in your scene.
