Anim. Curve
Enter the name of an existing animation curve. Its vertical direction maps into
the modification factor. The distance maps to the anim curve time axis (in
seconds).
You can use the drop-down list to the right of the box to list and select all the
anim curves with names starting with
propModAnimCurve
. You can also
create one of those by choosing Create New from the same drop-down list.
Scale U, Scale V
For Parametric (NURBS) Modification type only.
Distance Based On
The distance from the manipulator handle to the object directly influences the
modification factor. The distance is computed along the selected axes only.
Modification Falloff: NURBS Curve
For World Modification type only. This option uses a NURBS curve to create the
falloff. A NURBS curve profile can be used to produce a modification factor.
Enter the name of an existing NURBS curve. Its vertical direction maps into the
modification factor. The distance maps to the NURBS curve.
You can use the drop-down list to the right of the box to list and select from all
the NURBS curves.
Using the PropMod script
The PropMod script is similar to the Move script except that it has additional
settings for the move distance. Using the Script option, you can compute each
object’s factor individually.
The user-defined script command considers both the position of the manipulator
and the object. The value returned by the script is used as a multiplying factor for
a specific object.
Example
Create myPropMove.mel file as:
global proc float myPropMove
(float $mx, float $my, float $mz,
float $px, float $py, float $pz)
{
float $value = rand (1.0);
return $value;
}
...which produces a random value between 0 and 1.
If you select myPropMove as the script name, you get a random modification
factor for all selected points.
