Grid and contours

The map can show a grid and a contour overlay. Their buttons sit next to the opacity row in the left panel of background edit mode. Each button opens a settings popup, and the settings are saved per map and travel with the project file.

Grid

Draws a grid over the whole map. Useful for judging distances or for cell-based movement in TTRPGs.

Element	What it does
Show	Turns the grid on and off.
Shape	Choose a square or hex grid.
Size	The cell size. With Auto on, it follows the map size.
Anchor	Where the grid starts. Press Pick on map, then click the map to set it; Reset restores the default.

Contours

Draws contour lines that follow the heights of generated terrain. The lines stay hairline-thin at any zoom, and where a steep slope packs them tightly they read as a subtle shading.

Element	What it does
Show	Turns contours on and off.
Interval	The height between contour lines. Smaller values draw denser lines.
Smoothing	How much small wiggles are ironed out. Even at maximum, a small summit keeps its closed ring.
Color	The line color.
Opacity	The line strength.
Index lines	Emphasizes every 5th line to make heights easier to read.

Heights come from the terrain generator. A map painted only with the brush has flat heights and shows no contour lines. Painting water over generated terrain lowers that spot to sea level, which erases its contours as well.
