A gradient is a smooth linear transition from one color or brightness to
another, as shown below. Lens Effects use gradients to control aspects of the
lens flares, such as colors and transparency. Lens Effects use several
gradient
types
on page 6704 .
Lens Effects Gradients are always interpreted from left to right.
Gradient Flags
Gradients use Flags to indicate points along the gradient bar where you want
different colors or brightness values to be. The colors between the flags are
interpolated automatically by Lens Effects. Each Gradient inside Lens Effects
can contain up to 100 flags. The current flag is highlighted and green. The
position number above the gradient bar indicates the position of the current
flag, in relation to the overall length of the gradient.
A gradient always has non-moveable start and end flags. You can add up to
98 intermediate flags to alter the overall appearance of your gradients. You
can also change the color or brightness of the end flags to suit your needs.
When you place two gradient flags on top of one another, you create a sharp
break in the gradient. When a third flag is placed on top of the second flag,
a sharp edge appears in the gradient.
WARNING When you animate Lens Effects parameters, this creates pointers into
the actual scene, so Lens Effects animation is lost if you save the Video Post queue
in a VPX file on page 7967 . To preserve the animation, save the Video Post data,
including Lens Effects animation, in the MAX file.
Procedures
To add an intermediate flag:
■ Click the gradient bar where you want to place the new flag.
The flag uses the color of the gradient at the point where you placed it. To
adjust the color, double-click to display the
Color Selector on page 117 .
