Creating Mini Maps

After completing this tutorial, you will be able to create minimaps using the Sandbox Editor and Photoshop.

Creating a Minimap

To start off, you will have to edit the MapScreenshotSettings.xml with a text editor, the .xml file is located in the \Editor folder.

A lot of these settings can be tweaked to create the most desirable results, but make sure to create a backup copy of the original MapscreenshotSettings.xml.

<r_HDRRendering value="0">
<r_PostProcessEffects value="0">
<e_ScreenShotQuality value="0">
<e_ViewDistRatio value="10000">
<e_VegetationSpritesDistanceRatio value="20">
<e_ViewDistRatioVegetation value="100">
<e_Lods value="0">
<e_TerrainLodRatio value="0">
<e_Vegetation value="0">

Step 1

First, open the desired level in the Sandbox Editor for which you want create a minimap.

Step 2

Next, open the minimap function located on the RollupBar, on the Terrain pane.

Now when pressing the minimap button, a green bounding box, and a smaller blue "selection" box will appear on the terrain, this is sometimes at the 0,0,0 map coordinates.

To move the minimap bounding box, click and hold the right mouse button and move the blue "selection" box to the spot where you want to create your minimap.

Step 3

After you have moved the box, press the Use New Mini Map Area button to update the minimap bounding box to its new location.

The green bounding box shows the area that will be made into a minimap image, adjusting the camera height will therefore change the size of it.

To change the Camera Height, put the preferred height into the input box and press Use New Mini Map Area.

Adjusting the Resolution in the minimap properties will increase the size of the minimap image that the Editor generates. For example, choosing a resolution of 2048 will give you a minimap image of 2048x2048 pixels.

Step 4

Before going to step.5, make sure that the minimap bounding box is actually bigger than the actual play area of your map. Failing to do so can lead to anomalies if the player stands on the border of your map.

This is an important step and rule to keep in mind when creating minimaps, in order to prevent having to redo your minimap.

Step 5

Now, when you're all set and have selected your Camera Height, Resolution and area, be sure that you've selected hexadecimal or even numbers for the Camera Height if you know that you will add more detail to the minimap later on, i.e 256, 512, 1024, 2048 etc.

You can now go ahead and press the Generate MiniMap button.

A quick succession of images will flash in the upper left corner of the Editor, showing that your minimap is being created; this can take a few minutes depending on the Camera Height, Resolution and MapScreenshotSettings.xml.

Note: You should only choose to use very large resolutions (8192 or 16384) if you are running the editor on a very high spec system with a minimum of 8 GB of ram.

After the editor has finished, your minimap will be placed in \Game\ScreenShots\Map along with an .xml file.

The .xml file provides the CryENGINE with the map coordinates so that the player position is correctly displayed on the minimap.

Preparing the Minimap

Step 1

In Photoshop, open up the minimap image file that was just created.

To make sure that your minimap will display correctly in the game, you will need to desaturate the image and tweak its levels.

Step 2

To desaturate your minimap image, go to Image>Adjustments>Desaturate, this will essentially make your minimap black & white.

Step 3

Now, adjust the levels as a color overlay will be applied on top of the final image, you will need to have some outstanding black and white and clear grey tones, the better the levels are adjusted the more details players will be able to recognize.

Try to avoid creating completely black areas.

To start off, go to Image>Adjustments>Levels, this will open up the "levels" output box.

By adjusting the input levels you can create a well contrasted image.

Step 4

Now Go to File>Save As, this will open up the save as window, under formats choose the crytifplugin.

Go press save now as this will start the crytifplugin, which has a wide range of settings and options. For creating MiniMaps you will only need to use a few.

Step 5

First, change the Preset option from its default (diffuse_highQ) to Minimap.

Step 6

Next go to the Advanced pane and check to make sure that "Auto Optimize file" is deselected.

You can now press OK, and crytifplugin will now create a .TIF file – don't worry about the end file size.
The Resource Compiler will automatically create a .dds file for the target platform, specified in its settings.

IMPORTANT: You do not need the CryTifPugin for Photoshop to create a minimap. You can also use the .dds plugin from Nvidia to export the minimaps as DXT1.

Step 7

The minimap is now ready to be used, select the .TIF file and the .xml file that was created when you made your minimap and copy both files to your map folder.

If you already have an .xml file located in your map folder, you can merely open it with a text editor.

Inside the .xml file you will need to edit the numbers in the first line that shows the startX, startY, endX, and endY. Exchange the numbers here with the numbers located in your minimap .xml file.

Make sure that the MiniMap Filename points to the filename of your new minimap .dds image file.

Instead of putting in .TIF as the file definition you will need to put in .dds instead (the one the Resource Compiler will create from the .TIF, or you manually created via the NVIDIA plugin).

Note: If there are no numbers located in the .xml file, just copy the whole line from your minimap .xml file.

The minimap is now visible in the map.

Adding Detail to the Minimap

This process will require you to create several smaller pieces of your minimap and then later put them together using Photoshop.

This is generally only a process you will have to do if your PC is not able to handle the creation of high resolution minimaps.

Before starting, make sure that you have the NVIDIA Texture Tools installed in Photoshop. (

Step 1

Now, using Photoshop open your minimap .DDS file. The NVIDIA tools will recognize it and open up this property window, here you can just press OK .

With the minimap opened you can see here on this example below that the quality at 100% is not the best.

Step 2

Go back to the Editor, and select the minimap function.

For higher quality it's enough to change Camera Height and keep the resolution to the original minimap, this is important otherwise you will run into issues with image sizes not matching.

You will also need to change the lines listed below, in the MapScreenshotSettings.xml. These settings will raise the quality and the amount of objects visible.

<E_LOD_RATIO value="0"></E_LOD_RATIO>

After you've edited the MapScreenshotSettings.xml, you can press Generate MiniMap. This will again create a minimap image file and an .xml file, the .xml file you can safely delete as there's no need for it.

Step 3

Now go back to Photoshop and open up the minimap file the editor just created. Select the whole image by going to Select>All and select copy under Edit>Copy.

Go to your minimap that you want to add detail to under Edit>Paste, and place in the copied image.

Step 4

After you've done all that, it's time to resize the image you just pasted onto the minimap.

This is where the calculator will come in handy for you. If your minimap was created with a Camera Height of 512 for example, you should preferably generate the smaller minimaps in increments such as 256 or 128 etc.

If, for example, you generated smaller minimaps with 128, that will need to be divided by 512 to calculate the scaling percentage (128/512 = 0.25, which equals to 25% scaling.)

Step 5

When you've successfully scaled your minimap piece to its correct size, you'll need to move it to its correct position on the original minimap. emember to double check if it really fits correctly.

Repeat steps 2 to 5 as many times as you want to ensure that your minimap has a high level of quality. With a little bit of extra work you will have a very high quality minimap.
