FCRVSELECT

Light

 

The FcrvSelect->Light command in the Motion module displays the function curves for the animated parameters of the selected light in the Fcurve window. See the Light->Define command for information about light parameters.

For more information on all tasks related to editing function curves, see the Editing Function Curves section of the Animating User's Guide.

 

Procedure

  1. Select a light. You can use the Multi menu cell to select multiple lights.
  2. Choose the FcrvSelect->Light command.

The Fcurve window and the appropriate function curve(s) appear.

 

All

Displays all function curves available for the selected light.

Position

Translation

Displays the light position function curve on a path. The values on the vertical axis of the Fcurve window range from 0 to 1, and represent percentages of the length of the path. This function curve acts like an object's translation function curve.

Explicit Translation

Displays all explicit translation function curves of the light.

Explicit Translation X/Y/Z

There are three function curves, one for each axis. The values on the vertical axis of the Fcurve window are global coordinates.

Interest

Translation

For spotlight only. Displays the function curve for the interest of a spotlight on a path. There is only one function curve. The values on the vertical axis of the Fcurve window range from 0 to 100, and represent percentages of the length of the path. This function curve acts like an object's translation function curve.

Explicit Translation

Displays all function curves for explicit translation of the spotlight's interest. There are three function curves, one for each axis. The values on the vertical axis of the Fcurve window are global coordinates.

Explicit Translation X/Y/Z

There are three function curves, one for each axis. The values on the vertical axis of the Fcurve window are global coordinates.

Cone Angle

For the spotlight type only. Displays the function curve for the cone of the selected spotlight. The values on the vertical axis of the Fcurve window are in degrees, and range from 0 to 180.

Spread Angle

For spotlight type only. Displays the function curve for the spread angle of the selected spotlight cone. There is only one function curve. The values on the vertical axis of the Fcurve window are in degrees.

Colour

Displays the function curves of the colour of the selected light. There are three function curves representing the RGB values. The values on the vertical axis of the Fcurve window represent the intensity of the colour component and normally range from 0 to 1. They can be higher for special purposes.

Falloff Start

Displays the function curve of the falloff starting point of a selected light. The values on the vertical axis of the Fcurve window represent the distance from the light to the falloff starting point.

Falloff End

Displays the function curve of the falloff ending point of a selected light. The values on the vertical axis of the Fcurve window represent the distance from the light to the falloff ending point.

Umbra

Displays the function curve for the umbra colour of the selected light. The values on the vertical axis of the Fcurve window represent the umbra colour, and range from 0 to 1.

Visibility

Displays the function curve of the selected light when hidden. This is a linear curve with two values: 0 represents visible and 1 represents hidden states.

Area Geometry Rotation

Displays the function curve for the xyz rotation of the mental ray area light's geometry (in degrees) around the light's origin. For spotlights, the origin is the spot itself.

Area Geometry Scaling

Displays function curve for the xy scaling factor of the mental ray area light's geometry. For the Sphere and Disk geometry areas, it represents the radius of the light. For the Rectangle geometry area, it represents the scaling of the width (x) and the height (y) of the rectangle before rotations are applied (if any).
