Effect of Mouse Grid Position At Z

The following examples display the differences between not enabling the setting (the default option) and enabling it. When the setting isn’t enabled, Unity displays the Brush marquee at the default z = 0 position. To draw the following tiles, you position the mouse cursor within the area marked by the white marquee as shown below.

Enable Mouse Grid Position At Z to display the Brush marquee at the current z position. To draw tiles in the same position shown in Example 1, position your mouse cursor within the blue marquee area instead.
