Envelope Tool
The Envelope tool is a tool for editing an Envelope, which is an encapsulated volume that assigns weights to vertices. Each bone has an envelope, and any vertices that are within or affected by the envelope are assigned a weight.
Using the Envelope tool can make using Rigging Mode a little easier, as it allows you to assign weights more comfortably than manually selecting vertices to assign weights.
How to Use
Select the desired bones in the Scene or Bone Tree area, Bind Bone List.
