Pincel

Painting needs paint brushes and Blender provides a Brush panel within the Toolbar when in Weight Paint Mode.

Pincel

In the Data-Block menu you find predefined Brush presets. And you can create your own custom presets as needed.

Radio

The radius defines the area of influence of the brush.

Intensidad

This is the amount of paint to be applied per brush stroke.

Usar decaimiento

When enabled, use Strength falloff for the brush. Brush Strength decays with the distance from the center of the brush.
