Note
If you change the Input Parameter after you have already created keys, the existing keys remain in the same positions on the gradient bar.
However, their values may change as they will be adjusted relatively using the Start and End values for the new Input Parameter. For
example, if you had a key at frame 15 using Frame as your Input Parameter and Start and End values at 0 and 30, changing the Input
Parameter to Time would change that key to .5 (sec.). This is halfway between the default Start and End values of 0 and 1.
The Filter modulates the selected Input Parameter and allows you to have it applied at a rate other than linearly, the default. For
example, a linear curve is straight starting at the bottom left corner of the graph and ending at the top right. The input parameter is
applied evenly over the gradient bar. If you used a setting that bowed the curve up, the input parameter would change faster at the
steeper areas and slower where it is less inclined. If you were using Time as the Input Parameter, you would be scaling time to be
faster at the beginning and slower at the end of the gradient. If your curve slopes downward, the input parameter would be reversed
along this part of the curve.
Note
Since the Filter is only modifying the input, it has no (visual) effect on the gradient bar.
Adjusting Gain will make the curve(s) more or less pronounced S-shaped—the slope of the curve(s) is adjusted at the beginning and
end in opposite ways. Bias bows the curve(s). These settings can be used together and negative values are allowed.
The various Filter options (Linear, HiClip, LowClip, Sine1, etc.) provide different basic curve shapes. LoClip clips off low values
and stretches the high values. HiClip clips off high values and stretches the low values. The Sine options create oscillating or
undulating values.

The Gradient Bar graphically displays the key values set by the user. If the parameter is a color, the bar will be color and you will see
color transitions from one key to the next. If the parameter relates to numeric values, the bar will appear in grayscale. The lowest set
key value will be black and the highest will be white. The gradient colors will automatically adjust if you add or change a key value
that exceeds the previous minimum or maximum.
The Start and End fields set the beginning and end of the visible area of the gradient. There can still be keys set outside this range,
however. The Filter is applied to this range.
The Mouse buttons determine what happens then you click on the gradient bar. If Add is active, a key will be created at the point to
click. If Edit is active, you can grab an existing key and drag it left or right, but not past any other existing key. If Delete is active, a
key will be deleted when clicked on. Use the S
The current key is shown in the gradient bar in orange. Its value will be shown in the Key Value field, which can be edited. If the
parameter is a color, this will be a color selector button instead. The Key Parameter field indicates the numerical position of the
current key. Note that this value is not limited to integers.
Note
You can use the left and right arrow keys to select the preceding or next key as the current key. (Make sure that you do not also have an input
field active.) You may also select the current key by clicking while in the Edit mode.
