Show Flood Fill Preview | Enable this setting to display a preview when you use the Flood Fill tool and hover over the Active Target in the Scene view. If the preview displays many Tiles at once, performance can be negatively affected. You can disable this setting to improve performance. |
Flood Fill Preview Fill Extents | This setting is only available if you enabled Show Flood Fill Preview. Set the limit of the extent from the current cursor position that the Flood Fill preview displays. This value is the number of tiles extended from the current cursor position along the x and y-axis that the Flood Fill preview displays. Important: Setting this value to 0 causes the Flood Fill preview to have an unlimited extent, which can cause performance issues as the preview includes more tiles. You can improve performance by setting a lower value to limit the number of tiles included in the preview. |
Flood Fill Preview Erase Extents | This setting is only available if you enabled Show Flood Fill Preview. Set the limit of the extent from the current cursor position that the Flood Fill preview displays, when the Flood Fill tool erases tiles. This value is the number of tiles extended from the current cursor position along the x and y-axis that the Flood Fill preview displays. Important: Setting this value to 0 causes the Flood Fill preview to have an unlimited extent, which can cause performance issues as the preview includes more tiles. You can improve performance by setting a lower value to limit the number of tiles included in the preview. |
