Properties
<Affect_Region>.falloff Float default: 20.0 -- animatable
Distance in current units from the center to the edge of a sphere defining the affected region. Use higher falloff settings to achieve more gradual slopes, depending on the scale of your geometry.
<Affect_Region>.Pinch Float default: 0.0 -- animatable
Raises and lowers the top point of the curve along the vertical axis. Sets the relative "pointedness" of the region. When negative, a crater is produced instead of a point. At a setting of 0, Pinch produces a smooth transition across this axis.
<Affect_Region>.Bubble Float default: 0.0 -- animatable
Expands and contracts the curve along the vertical axis. Sets the relative "fullness" of the region. Limited by Pinch, which sets a fixed starting point for Bubble. A setting of 0 for Pinch and 1.0 for Bubble produces a maximum smooth bulge. Negative values for Bubble move the bottom of the curve below the surface, creating a "valley" around the base of the region.
<Affect_Region>.ignoreBackfacing Boolean default: off
When on, affects only those vertices whose face normals are in the same general direction as the gizmo arrow. When turned off, all vertices in the Falloff group are affected.
<Affect_Region>.start_point Point3 default: [0,0,0] -- animatable
The starting point for the application of the affect region.
<Affect_Region>.end_point Point3 default: [0,0,25] û animatable
The end point for application of the affect region.
Methods
AffectRegionVal <distance> <falloff> <pinch> <bubble>
The standard affect region function, based on a distance and the three affect region parameters (same as the editable mesh). This function is a cubic curve which returns 1 at distance 0, 0 if distance is greater than falloff, and other values for distance between 0 and falloff.
Notes
The Ignore Back Facing property is not accessible to MAXScript in 3ds max 4.
