Position

This defines the relative location of the Outline

• Inside means the Outline starts at the shape's border and grows toward the inside
• Center means it grows in and out from the shape's border
• Outside outlines start at the shapes border and makes the shape bigger.

Layer

When set to Simple the outline is rendered in the same polygon than the face color

If set to Back, then a new geometry is created for the outline. This solves the issue when big outlines overlap and hide the next/previous character.

Width

This is how wide the outline is.

Color

The Outline's base color.

Softness

Defines how blurred is the line between the Face and the Outline. Higher values will make the face seems to fade into the outline.
