### Overview
|

|
|
|
|
|
|
|
|
Surfaces rendered with the polygonOffset keyword are rendered slightly
|
|
|
|
|
off the polygon's surface. This is typically used for wall markings and
|
|
|
|
|
"decals." The distance between the offset and the polygon is variable.
|
|
|
|
|
If no value is supplied a distance of 1 is assumed, however this is
|
|
|
|
|
meant for backwards compatibility. Being explicit will help grepping
|
|
|
|
|
values later in case you need to find all surfaces with just a
|
|
|
|
|
polygonOffset of 1.
