Assigning a Focus Point to a Lighting Instrument Assigning a Focus Point to a Lighting Instrument One or more instruments and/or multi-circuit instruments can be focused on a focus point. The focus point is used to draw light beam representations (see Drawing Light Beam Representations), calculate photometric values (see Obtaining Photometric Data), and for rendering gobo projections (see Gobo Projection Requirements). In 3D views, the instrument rotates to point automatically at the focus point.
With the Focus Instruments at Next Click context menu command, selected lighting instruments can quickly focus on an existing focus point, or create one using the current focus point properties. Alternatively, use the Focus Instruments command to select an existing focus point, or create one and set its properties at that time.
To focus the lighting instrument at the next click with the context menu command:
Select the instrument.
Right-click (Windows) or Ctrl-click (Mac) in an open area of the drawing, and select Focus Instruments at Next Click from the context menu.
To create a new focus point for the instrument, click in the drawing. The current focus point properties are used, and a unique name is automatically assigned to the new focus point; see Creating a Focus Point Object. Alternatively, click an existing focus point or locus.
The instrument to assigned to the new or existing focus point.
If you place a new focus point on an existing 3D object while in a 3D view, the focus point automatically adopts the Z value of the click.
To focus the lighting instrument with the menu command:
Select the instrument.
Select Spotlight > Focus Instruments.
Alternatively Right-click (Windows) or Ctrl-click (Mac) on the selected instrument, and select Focus Instruments from the context menu.
The Focus Instruments dialog box opens. Select an existing focus point, or select Next Click to create a new focus point with the next mouse click and click OK.
If Next Click is selected, the New Focus Point dialog box opens. Specify the name and height of the focus point.
To change the focus point of a single instrument, enter the name of the new focus point in the Focus field of the Object Info palette (see Lighting Device Properties).
