Sets a key on the parameter function curve if the parameter is
single-linked (l_fcv) or sets a set of relative values in the
Interpolator object if the parameter is multiple-linked (l_interp)
or object's orientation linked (l_interpOri).
An Interpolator object is created when linking a parameter with
multiple driving parameters or with an object's orientation. It is
used to access and store sets of relative values.
If A is single-linked with B, then there is a link function curve
that animates the value of A as the value of B changes. On this
function curve, the Y axis represents values of A, and the X axis
represents values of B. SetRelativeValues "A" sets a key on this
function curve using the current values of A and B.
SetRelativeValues( [InputObj] ); |
| Parameter | Type | Description |
|---|---|---|
| InputObj | String | Parameter that is
linked with (controlled by) another parameter.
Default Value: Currently selected and marked parameters |
