Note - Tileset brushes are stored inside their respective tileset assets.
Layout (autotile only) : Indicates whether autotile atlas was generated from a basic or extended layout.
Inner Joins (autotile only) : Indicates whether autotile atlas includes the artwork for inner join tiles.
Type : Indicates whether tileset brushes are procedural or non-procedural by default. This option can be overridden by individual tileset brushes.
Width, Height : Size of atlas texture in pixels. The reflected size may differ from the actual size of the texture image according to the way its import settings are specified within Unity.
Rows, Columns : Maximum number of rows and columns of tiles within atlas.
Size of single tile in pixels excluding any additional border size.
Border : Border size in pixels that surrounds each tile. The offset between tiles can be calculated as:
Horizontal Offset = Tile Width + ( Border Size × 2 )
Vertical Offset = Tile Height + ( Border Size × 2 )
Delta : UV coordinates can be inset by a small amount to avoid visual artifacts when viewed. The UV delta specifies the percentage of a pixel to indent by.
