Options

Paint options.

The Weight Paint Options modify the overall brush behavior:

Restrict

This option limits the influence of painting to vertices (even with weight 0) belonging to the selected vertex group.

X Mirror

Use the X Mirror option for mirrored painting on groups that have symmetrical names, like with extension «.R»/ «.L» or «_R» / «_L». If a group has no mirrored counterpart, it will paint symmetrically on the active group itself. You can read more about the naming convention in Editing Armatures: Naming conventions. The convention for armatures/bones apply here as well.

Topology Mirror

Use topology-based mirroring, for when both sides of a mesh have matching mirrored topology. See here for more information.

Show Zero Weights

To display unreferenced and zero weighted areas in black (by default). This helps to identify areas with very low weights that have been painted onto.

None

Deactivated.

Active

Only the active group.

All

All groups.

Unified Settings

The Size, Strength and Weight of the brush can be set to be shared across different brushes, as opposed to per brush.
