The Sandbox

The Sandbox is Menyr's terrain creation tool. You drop shapes, Menyr computes relief with erosion, water flow and vegetation.

It only applies to Open World boards: a Dungeon board has no terrain.

Opening the tool

Click the castle icon in the toolbar on the left side of the screen.

The panel opens on four collapsible sections.

Section	What it does
Topography	Place the shapes of the relief, then run the computation
Biome	Repaint vegetation by hand
Sculpt	Reshape the terrain manually
Road	Place landmarks and connect them

Topography: shaping the relief

Drag and drop a shape from the panel onto the ground, then adjust it with the gizmo.

Step by step:

1. Expand the Topography section
2. Drag and drop a shape onto the ground
3. Move it with the gizmo, press R to switch to rotation or scaling
4. Repeat until you get the silhouette you want
5. Click Generate Biome to run the computation

The Clear and generate landforms button starts over from a random generation: handy when you have no starting idea, or to wipe everything.

Generate Biome

This is the button that turns your shapes into detailed terrain, with its relief, water flow and vegetation.

Expect 2 to 3 minutes depending on your processor.

Biome: repainting vegetation

Once the terrain is computed, the Biome section lets you paint over what the generation produced: turn a patch of forest into a clearing, lay cobblestone along a path, clear ground for a village.

Five brushes are available: grass, conifers, broadleaf, cobblestone and sand. Pick one, then set the size with the Brush Size slider.

See Biomes and vegetation.

Sculpt: reshaping by hand

The Sculpt section is for finishing touches: digging a cave entrance, rounding an edge, flattening a build site.

Three tools are available, with a brush size setting.

Sculpting makes your saves heavier

It is CPU-hungry and noticeably increases the size of your save files. For a major relief change, go back to your shapes in Topography and run Generate Biome again: it is faster and much lighter.

Road: tracing roads

The Road section places landmarks and connects them. Menyr computes the path from one point to the other.

The path is saved. To recompute it, move one of the two points.

Generation sizes

Size	Area	Available
S	1 km²	coming
M	25 km²	coming
L	100 km²	yes

Today, only the 100 km² size is available.
