3 Drag the light and drop it into the palette (right pane of the Lighting
tab). This will automatically be added to the scene.
NOTE If you drag a light studio into the palette, this will replace any existing
lights with those that make up the light studio.
As a general guide, the more lights there are in a scene, the longer it will
take to render it photorealistically. For external rendered scenes, you
may consider using the Standard Light Studio from the
Recommended archive as a starting point, then strategically add a
couple of Point and Spot lights around the scene. Point lights are
good to light up a dark area of the scene, while Spot lights can add an
element of drama and enhance realism.
To position or reposition lights in the model
1 Open the Presenter window, and click the Lighting tab.
2 In the palette (right pane of the Lighting tab), right-click the light you
want to reposition, and click Edit on the shortcut menu.
3 Use the Light Editor to position the light as needed.
Point, Distant, Spot and Projector lights have a Location parameter.
Distant and Spot lights additionally have a To parameter. You can
type in X-, Y-, and Z- coordinates for these, or alternatively use the Pick
button to interactively pick a point in the scene where the light and/or
target is located. The light is represented by a 3D wireframe sun icon in
the scene and the target by a wireframe sphere. The currently selected
light is drawn in the selection color (see Selection Page (page 709) for
more information).
NOTE Autodesk Navisworks does not allow you to pick a point in empty
space so you must pick a point on the model.
4 Lights can be positioned interactively. The 3D wireframe sun icon,
representing the light, has six bars extending out along the X- axis, Y-
axis and Z- axis. Hover the mouse pointer over one of the bars. The
mouse pointer will change to a hand and the bars will extend further
along that axis. Hold the left mouse button down to hold on to the light
and move it in either direction, along the extended bar. Release the left
mouse button to release the light in its new position. This can be
performed for all three axis.
5 Lights can also be positioned in the current location of the camera, which
can be anywhere in the scene. Navigate to the location where you want
the light to be positioned. Right-click the light in the palette (right pane
