Vertex Paint is a Modeler
plug-in that lets you interactively "paint" a
vertex color map on objects and weight maps
on skelegons.

A vertex color map is
a LightWave® feature that lets you assign
colors to an object's vertices (i.e., points).
Vertex color maps are a basic LightWave® feature
so you can render their effect without using
surface shader plug-ins. Although similar
to Modeler'sAir Brush tool, Vertex Paint
has its own independent interface for painting.

LightWave® skelegons
let you define bones in Modeler. Weight maps
can provide additional deformation information.
Vertex Paint provides a variety of features
for you to set weights for skelegons. You
can see how the weight will deform the object
in real-time while painting.

The Vertex Loader plug-in
can be used to load the bone information
modified in Layout and use it to edit weights.
