  • This wiki entry explains the terrain editing with QSF.
    In order to get a functional terrain in the editor without any failures, you'll have to create all three terrain bases: The height map, the blend map and the color map. All of these three maps are necessary to create the terrain in a proper way, otherwise the terrain won't be as it should be.

    Terrain modeling

    Basics

    With the terrain modeling you can create the height map. You can open the tool with the option Tool --> Terrain Modeling. All control options will be explained below:



    Brush Type: The brush type defines the type of "pencil" used by the modeling tool. If you choose 'Dome' for example, the tool is shaped as circle and the outlines are very soft and steady.

    Brush Size: The brush size defines the working area of your brush tool. It's important to know, that the working area isn't only affected by the brush size, also the intensity can affect it.

    Brush Intensity: If the intensity is higher, the adaption of the terrain will be more effective. If you choose lower values you can work more accurate.

    Randomness: If you want more randomness and inconsistence in the editing, you should rise this value.

    Import height map: Imports any existing height map. The file has to be .tif or .tiff.

    Export height map: The height map of the running map will be saved.

    Usage

    There are three different options for terrain modeling: You can raise or lower the terrain, smooth it or set a certain height for an area. Below you can find explanations for each option:

    Raise/Lower: If you press the left mousebutton, you can raise the terrain. If you press Shift + left mouse button, you can lower the terrain. (Shift needs to be pressed the whole time)

    Smooth: With this option you can smooth irregularities of the surface.

    Set/Pick: Just use the 'Height' field to set a certain height. If you press Shift + left mouse button, you can pick the terrain height of certain areas.


    With this three tools you can achieve completely different results. For normal usage, the tools 'Set / Pick' and 'Smooth' are sufficient.

    Terrain texturing

    Basics

    With the texturing tool you can create the blend map. The blend map defines the textures on the floor. You can open the tool with Tool --> Terrain Texturing. It offers the following control options:



    Brush Type: The brush type defines the type of "pencil" used by the texturing tool. If you choose 'Dome' for example, the tool is shaped as circle and the outlines are very soft and steady.

    Brush Size: The brush size defines the working area of your brush tool. It's important to know, that the working area isn't only affected by the brush size, also the intensity can affect it.

    Brush Intensity: If the intensity is higher, the adaption of the textures will be more effective. If you choose lower values you can work more accurate.

    Randomness: If you want more randomness and inconsistence in the editing, you should rise this value.

    Import blend map: Imports any existing blend map. The file has to be .tif or .tiff.

    Export blend map: The blend map of the running map will be saved.


    Usage

    The usage of the texturing tool is very similar to the terrain editing tool. With the left mouse button you can set the textures of the terrain, with Shift + left mouse button you can delete the texture from the terrain. It's important to know, that different textures have various 'resistances', so some materials are harder to edit.

    The whole map is separated in small chunks. You can recognize the different chunks by the white lines. Each chunk can only contain four layers of textur at the same time.

    Texture painting

    Basics

    The terrain painting creates the color map. The color map is responsible for discolorations of the terrain. You can change the visual setting of certain areas without editing the completely texture. This function can be used, to give landscapes a more realistic look. You can open the tool with Tool --> Terrain Painting. Afterwards, you'll find the following options for editing:



    At first you should choose a color. Click on the button Color, choose a certain color and press 'OK'. If you want to save the color, you'll have to press on the + in the upper left corner of the window. Now you can click on the first one of the two paint buckets below and start painting the terrain. If you choose the second paint bucket, you can edit the alpha channel of the terrain textures and hide certain areas of the terrain. If you want to redo this, you'll have to press Shift + left mouse button.

    Import Palette: Imports an existing palette which is already filled with colors.

    Export Palette: Exports a .pal file with choosen colors of the current map.

    Import Color-Map: Imports an existing color map. The file has to be .tif or .tiff.

    Export Color-Map: The color map of the running map will be saved.

    Usage

    The painting tool isn't very different from the other ones. If you want to redo a painting, you'll have to use the color with the code #7f7f7f.

    After the usage of all three tools fir the first time, you should save the work. Afterwards the map will be loaded correctly by the next start of the editor and you can go on with the work without any annoying preparations.
