Terrain
Terrain mode has 3 submodes: Heightmap, Lakes and Flags.
Terrain is built from a heightmap. This editor mode allows you to edit the heightmap and see the effects on terrain immediately.
You use brush to paint on terrain - whether it's height paint, texture paint, or anything else.
Radius of the brush. The larger the size, the bigger the area affected by brush.
Currently, brush supports 3 shapes: Square, Circle, Diamond. Circle is the default shape, and is usually enough for most cases.
Depends on draw mode (see below)
There are 4 interpolation modes for painting brush, all of which affect relative strength of the brush in the painting area: Constant, Linear, Square, Sinusoidal.
Heightmap editor has 5 sculpt modes available to shape the terrain.
Add mode simply adds height to existing terrain. Subtract mode takes that height away. Strength denotes the height displacement at the center of brush on a single stroke.
Set mode sets height at a desired value. Interpolation mode does not apply. Value denotes the height the terrain will be set to.
Smooth mode smooths out/roughs up terrain, diminishing/attenuating irregularities. Value denotes how much the terrain will be smoothed out/roughed up in a single stroke, and should be a value between 0 and 100.
This mode does not have an inspector.
You can use Left Mouse Button or Right Mouse Button to modify terrain.
- Add mode: LMB to add terrain, RMB to subtract terrain
- Set mode: LMB to set terrain, RMB to probe terrain (get height value)
- Smooth mode: LMB to smooth out terrain, RMB to rough it up
Terrain height can't be lower than 0 or higher than 65535. Terrain with height 0 denotes area submerged in ocean and is impassable.
You can't modify terrain under a lake.
This mode is very simple. It allows you to add and remove lakes, and to change lake types.
You can change appearance of selected lake by changing its type. Available types: Water, Swamp, Lava, Ice.
Read-only. Depth of selected lake at its deepest point.
Use LMB on a terrain which is not submerged in lake to create a new lake. The lake will flood all neighbouring terrain below the terrain at 3D cursor position. If the terrain is flat as a pancake, the water will have nowhere to go, and the lake will not be created. Therefore, you should click on sloped terrain for desired results. Any existing lakes which make contact with the new lake are assimilated into the latter.
Use LMB on a terrain submerged in lake to select that lake.
Use RMB on a terrain submerged in lake to remove that lake.
Use RMB anywhere else to deselect any selected lake.
While terrain tiles (see Textures mode) can have optionally set movement and visibility flags, you can set custom flags in this editor mode. This is sometimes a necessity - many objects in game don't have built-in collision mesh and units would simply pass through these objects, were it not for the custom flags.
You use brush to paint on terrain - whether it's height paint, texture paint, or anything else.
Radius of the brush. The larger the size, the bigger the area affected by brush.
Currently, brush supports 3 shapes: Square, Circle, Diamond. Circle is the default shape, and is usually enough for most cases.
There are two modes: Movement and Visibility. You can set custom flags depending on which flag mode you are in.
Tile movement flags are maroon. Custom movement flags are bright red. Custom visibility flags are bright yellow. If a tile is affected by both visibility and movement flag, it turns orange. As for now, there are no tile visibility flags - it appeared that not a single official map uses those.
This mode does not have an inspector.
Use LMB to set custom flags on terrain according to flag mode. Use RMB to remove custom flags from terrain according to flag mode.
