Creating and Using Falloff Zones
Falloff Zones are Poser’s fundamental method of creating smooth bending figures by blending between two bones or body parts. You can use falloff zones on any type of rotation (such as Bend, Side-Side, Front-Back, or Up-Down). A Falloff Zone section appears in the Joint Editor where it is appropriate to use falloff zones on a joint. When a joint property can utilize Falloff Zones, the Joint Editor displays a Falloff Zones area that appears as shown in the following figure.

There are three types of falloff zones: Spherical, Capsule, and Weight Map (the latter being editable only in Poser Pro 2012 and later), described in the sections that follow. Multiple Falloff Zones can be combined, regardless of type. You can blend multiple falloff zones together in a single joint. The type of blending can be set as Multiply, Add, or Replace in the Joint Editor. You can learn more about blending in Blending_Multiple_Falloff_Zones.
