Distance from Object

The Distance from Object modifier alters the base property with a new one from a given range using the distance to the active camera or to a given object as the parameter.

Target(ターゲット)

The object to measure distance from.

Range Min, Max

The limits of the mapping from "distance to camera" to "property in mapping". If the current point of the stroke is at Range Min or less from the active camera or the object, it will take the start value. And conversely, if it is at Max or more from the camera/object, it will take the end value. These values are in the current scene's units, not in pixels!

Fill Range by Selection

Set the min/max range values from the distances between the current selected mesh vertices and the camera or the target.
