    Face Edit Mode

Height mode is designed to allow quick and easy creation of mountains and valleys.
There are 3 height mode types, accessible using the number keys (1-3)

1 = Standard height mode
In this mode, left click and drag to raise areas of the map.
Hold down the shift key while left clicking and dragging to lower the map

2 = Vertical drag
In this mode, left click and drag up or down to raise or lower only the selected area

3 = Horizontal drag
In this mode, left click and drag to horizontally adjust the terrain.  Useful for smoothing shore edges (ensure static water is disabled)


Advanced height mode options

    Water settings

When editing the height of the map it may be useful to only effect land, only effect water, or to effect both.  To toggle these modes, use the F3 key.  These modes currently only have an effect while in height mode, and in smooth mode.

    Level Caps

It is often useful to be able to limit the effect of height modifications. Press the F5 to cycle cap modes.
There are 4 cap modes: Upper Cap, Lower Cap, set to height, and no cap.  To adjust the value of these caps, use the F6 and F7 keys.  These modes currently only have an effect while in height mode, and in smooth mode.

    Brush Size

To change the size of the area being adjusted, use the + and – keys to adjust the brush size, or drag the slider at the bottom of the screen.
This option has effect in Height Mode, Terrain Mode, and Smooth Mode.

    Brush Sensitivity

It is often useful to be able to make only very slight changes to height, or to make very extreme ones.  To change brush sensitivity press + or – while holding the Shift key, or drag the slider at the bottom of the screen.  This option has effect in both height, and smooth mode.

Terrain Mode is used for paining textures onto the terrain.  The terrain type may be selected using the number keys (1-7), or by selecting a terrain type from the popup list.

1 = Ocean
2 = Mountain
3 = Desert / Steppe
4 = Plain
5 = Snow
6 = River
7 = Forest
8 = Steppe Forest
9 = Snow Forest

Click and drag to paint with the selected texture.  
Notes:
Forest tiles, have one tree per tile.  
The M&B engine can only handle around 5000 forest tiles on the map before it crashes.
The only difference between ocean tiles, and river tiles is the direction of flow.  There are currently only 2 directions rivers may flow, so it is advised to try and keep all rives roughly aligned with this 1 axis.

Select the terrain type, as with Terrain Mode, and click to fill all tiles of the selected type that are connected to the selected terrain type, with the chosen new texture.  Note that there is a limit to the amount of tiles that will be filled in 1 fill, however it is a simple matter of filling a number of times to fill large areas.

This mode is for editing towns and spawns.  To move a town or spawn point, click it, and drag it until it is in the desired position.  Note that spawns, or towns that spawn parties may not be placed on or near impassible tiles, or they will cause a crash while in game when a party spawns from them.  Keep in mind that parties may spawn within a radius of a town (depending on your scripts), so even if it is just on valid terrain, it may still cause a crash.

You can also drag the map camera borders (the red planes that stop the camera leaving the main play area) to allow the player to explore more of your map.

To change town names, select the town and press enter.  Backspace the old name, and type in the desired name.

Press TAB to de-select selected town or spawn.

To change a town icon, select the town and press the + or – keys.

Vertex mode is for adding miner detail than in height mode.  Use the number keys (1-4) to select the axis to effect when dragging vertices.

To select multiple vertices, click an empty location, and drag the mouse, or hold shift and select each vertex individually.  To move the vertices, click and drag one of those selected.

Press TAB to de-select all selected vertices.

To weld a vertex to another vertex, hold the control key, and drag a vertex (or number of vertices) onto another vertex.  The selected vertices will be removed, and faces adjusted to connect to the new vertex.  Faces that result in two corners sharing a vertex (ie that would be invisible) are deleted. NOTE: DO NOT WELD SO THAT ONE EDGE HAS MORE THAN 2 FACES, IT WILL CAUSE A CRASH IN GAME.  You may also weld vertices that are (very) close together, by selecting them, and pressing Ctrl-V.

Vertex mode also allows scaling of vertices.  Scaling has 2 modes: relative, and absolute scaling.  To change scale mode, press F8 while in vertex mode.  In relative scale mode, vertices are scaled relative to the centre of all vertices selected, and in absolute mode, vertices are scaled relative to the origin of the map.  All scaling is performed on only the selected axis, as with movement.

Smooth mode is for removing any extreme bumps in the terrain.  Click and hold to adjust the height of nearby tiles toward the average height of all tiles in the area.  It is best to have a reasonably large brush size for quick smoothing.

This mode is for similar use as the vertex mode, however also allows face cloning and deletion.

To select faces to operate on, click to select a single face, or hold shift to drag select many, in a similar way as with vertex mode.  You can also double click a face, to "fill select" all faces of the same texture type.  For example clicking a plane tile, will select all adjoining plane tiles.

Faces may be moved in a similar way to vertices.

To delete selected faces, press delete.

To clone the selected faces, hold control, and click and drag as with moving.
