Default Brush properties
The following properties are visible by default when you select the Default Brush. Some properties are common to all brush types.
| Property | Description |
|---|---|

You can use or create your own Scriptable Brushes, which then become available from the dropdown menu. The Script property updates to reflect the current active brush. |
| Flood Fill Contiguous Only | Enable this property to have the Flood Fill tool only affect tiles on a tilemap which are both the same as the targeted tile and are contiguous to each other from the targeted position. When disabled, Flood Fill will change all tiles which are the same as the targeted tile on a tilemap regardless of their position. This only affects the Default Brush. |
| Lock Z Position | Enable this property to change the z-position of the active brush. Disable to prevent any changes to the current z-position of the active brush. |
| Z Position | Only available when Lock Z Position is disabled. Enter the desired z-axis value (only whole numbers) for this brush when painting tiles, which also adjusts the relative heights of tiles on a Z as Y Isometric Tilemap . Refer to Adjusting the Tile height in the Palette for more information. |
| Reset | Select to reset the z-position value back to zero. |
