The script is used to limit the amount of vertex groups that affect a particular vertex / vertices. This is useful for rigging and animation for real-time applications, such as games, where a vertex can usually be affected by a maximum of 4 different vertex groups. The script provides two operators for this task.

Select Vertices With Num Vg - selects vertices of a mesh, depending on how many vertex groups they have assigned. Options are:
- n (amount of vertex groups)
- Equal or Greater Than n
- Equal n
- Equal or Less Than n

Remove Excess Vertex Groups From Verts - it does just that, it removes excess vertex groups above a user specified number. It removes the weaker groups i.e. the groups that affect a vertex less than other groups.
