It allows you to add and position any light source in the 3D scene.
How to use
1. Click the Light tool icon or choose the Tools > Cam/Light > Light command from the menu.
2. The program console prompts Local axes origin.
3. Locate the curve axes origin following one of the two methods:
a) Click and drag in any view and release the mouse button to confirm placement.
b) Type its XYZ coordinates in the console (values must be separated by a comma, i.e. 1,2,3) and press Enter to confirm. If you press Enter without typing any value in the console, the axes origin of the curve will be placed in correspondence with the XYZ origin.
At this point you have positioned a light source in the 3D scene but no lighting characteristic has been defined yet. Now, any light shader can be assigned.
To successively select a light, you can simply click it in any view or choose it using the Hierarchy Browser, which lists all the lights in the 3D scene twice. The first time, under World, they are displayed in order of insertion in the scene; the second time, under Lights, they are displayed together so that you can have a quick feedback on which lights are in the scene.
Options
Position
To modify XYZ coordinates of the light position.
Views. Choose the Edit mode. Pick the Position hotSpot and drag it. Release the mouse button when you have reached the desired location.
Modeling Tool panel. Type the coordinates values in the XYZ data fields and confirm them by pressing Enter.
Target
To modify XYZ coordinates of the light target.
Views. Choose the Edit mode. Pick the Target hotSpot and drag it. Release the mouse button when you have reached the desired location.
Modeling Tool panel. Type the coordinates values in the XYZ data fields and confirm them by pressing Enter.
Aperture
To adjust the angle of distribution of the light.
Modeling Tool panel. Set the degrees value either by moving the slider or by typing it in the data field and pressing Enter.
Note: Depending on the light shader you assign to the Light tool, the above mentioned options may be accessible or not. Specific light parameters are available as arguments of each light shader and listed in the Shading panel.
