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.

Elevation color

Turning on Elevation color in the contour popup tints the land by height, the way an atlas separates lowland from high mountains. It works on its own, with or without the contour lines.

Control	What it does
Elevation color	Turns height tinting on and off.
Gradient	Previews the color ramp. Click the ramp to open its editor.
Color strength	How strongly the tint sits over the terrain.

Clicking the ramp opens an editor where you set the colors yourself. Click an empty spot on the ramp to add a color stop at that height, then drag stops around or change their color and position. Two stops is the minimum.

Stepped in the same editor divides the colors into bands at the contour interval, so every color boundary lands exactly on a contour line. With it off, the colors blend smoothly by height.

Editing heights

Start editing in the contour popup’s Edit heights row lets you raise and lower the land directly. Heights are only visible as contour lines and elevation color, so the button works only while contours are shown.

Control	What it does
Raise / Lower	Whether the brush raises or lowers the height.
Size	The brush size.
Strength	How much the height changes per stroke.
Done	Ends height editing and returns to the tool you were using.

Only the height changes; the terrain color stays as it is. Water is left alone, and lowering never pushes land below sea level. One stroke is one undo step.
