Affect Region

Follow this tutorial on how to use the affect region modifier in 3ds Max!

Affect Region

The Affect Region modifier lets you form a bulge or indentation in the surface of an object, using a sherical fall-off region that influences nearby vertices. It works similarly to Soft Selection, giving you gradual deformation rather than a hard edge.

Parameters of the Affect Region

Sets the radius of affected vertices, in units, from the base of the gizmo arrow.

When on, affects only those vertices whose face normals are in the same general direction as the gizmo arrow. When off, all vertices within the Falloff range are affected.

You can change the following parameters to edit your model: Falloff Ignore Back Facing Pinch Bubble

Affects the tangency of the curve where it meets the gizmo arrow tip. Positive values produce a pointed tip while negative values produce a dimple.

Changes the curvature of the affected vertices. A value of 1.0 produces a half-dome. As you reduce this value, the sides of the dome slope more steeply. Negative values lower the base of the curve below the base of the arrow gizmo.
