Parameters:

-----------

Outline Weight = Adjusts darkness of the outlines.
|
|
|
|
At lower internal resolutions, smaller values work better to
|
|
reduce the appearance of lines around individual areas of some
|
|
textures. At higher internal resolutions, setting both a higher
|
|
outline weight value plus increased blur factors will work
|
|
together to thicken the appearance of the lines.
