Cone Angle
The Cone Angle manipulator is a cone whose base you can adjust. By wiring its Angle value to a parameter of another object,
you can create a custom control, with visual feedback, within a scene.
Cone angle manipulators are used by a spotlight's Hotspot and Falloff controls.
Procedures
To create a cone angle manipulator:
- On the
Create panel, activate
(Helpers) and choose Manipulators from the drop-down list.
- Click to turn on Cone Angle.
- Drag in a viewport, and then release the mouse.
The cone angle manipulator is created along the negative Z axis of the viewport in which you drag. In other words, its initial
position points away from you.
To change the angle of a cone angle manipulator:
- Turn on
(Select And Manipulate).
TipIf you are still in the Create panel, turn on
![](../images/GUID-103C0FB3-CA74-4C80-9CAF-FA8E106752EF-low.png)
(Select Object) before using the manipulator. Otherwise, it is too easy to create a new one.
- In a viewport, move the mouse over the manipulator.
The manipulator turns red when the mouse is over it and it is available to be manipulated. Also, a tooltip appears, showing
the name of the manipulator and its current value.
- Drag the base of the cone angle manipulator's cone.
The Angle value changes as you drag the manipulator. This value can range between 0.0 and 180.0.
To select a cone angle manipulator:
- Turn on
(Select Object).
You can also use
(Select And Move),
(Select And Rotate), and
the scale options on a cone angle manipulator.
- Turn off
(Select And Manipulate).
If you don't turn off Select And Manipulate, you adjust the manipulator's Angle value without affecting its properties.
- Adjust the properties of the selected manipulator.
To connect a cone angle manipulator so it controls another object:
-
Select the cone angle manipulator.

- Close the Parameter Wiring dialog.
Now when you turn on
(Select And Manipulate) and use the manipulator, the object updates under the manipulator's control.
