Modify a 3D object’s inherent size and orientation in Motion

Although you can’t edit 3D objects in Motion, you can use controls in the 3D Object Inspector to change an object’s inherent size and X, Y, or Z orientation. It’s a good practice to adjust these parameters before you animate a 3D object or when:

  • You import a 3D object that’s not modeled to scale, or you need to adjust an object’s inherent size to better suit your project

  • You import a 3D object saved from a 3D modeling app that doesn’t share Motion’s 3D coordinate system, resulting in the object being rotated in the wrong direction

  • You import multiple 3D objects (especially from different sources) with varying scales or orientations

Adjust the unit size of a 3D object

3D modeling applications use real-world units of measure, such as inches, meters, feet, and so on. When a 3D object is added to a project, Motion normalizes the size of the object so that it properly scales within the pixel-based units of a Motion project.

  1. In Motion, select a 3D object in the Layers list, Timeline, or canvas.

  2. In the Inspector, click 3D Object (if it’s not already selected).

  3. Choose one of the following from the Unit Size pop-up menu:

    • Automatic: Sets the units of the 3D object to the equivalent of approximately 500 pixels in the Motion project.

    • Original: Sets a 1:1 translation of units to pixels. This may result in an object so small that it’s not visible in the project canvas, or so large it extends well beyond the edge of the canvas.

    • Custom: Lets you manually set the size of the 3D object by dragging a slider (or entering a specific amount in a value field).

      Although Custom is disabled when you select Automatic or Original, its value updates to display the current Unit Size value of the 3D object.

      Changing the Unit Size value does not affect the 3D object’s Scale parameter value in the Property Inspector.

      Note: When you resize a 3D object, there’s no computational advantage to using the Custom Unit Size parameter over an object’s Scale parameter in the Properties Inspector. Once you’ve defined values in the 3D Object Inspector, you’ll generally use parameters in the Properties Inspector for transforming or animating your objects.

Change the orientation of a 3D object

  1. In Motion, select a 3D object in the Layers list, Timeline, or canvas.

  2. In the Inspector, click 3D Object (if it’s not already selected).

  3. Click the disclosure triangle to reveal separate dials for rotating around the X, Y, and Z axes, then adjust the dials (or enter specific amounts in the value fields).

    Changing the X, Y, and Z Orientation values does not affect the 3D object’s Rotation parameter values in the Property Inspector.

You can also lower the amount of light reflected in the surface of all 3D objects in the project to create more dramatic and realistic shading, especially if you plan to add lights to your project. See Adjust the 3D object environment lighting in the Inspector.
