Creating the Mini-Map

To create a map overview, follow these steps:

Sample Map Overview from dod_flash.
  1. Start the game using 1280x1024 Video settings on Normal
  2. Make sure the "Far Z Clip Plane" is disabled in the env_fog_controller
  3. Load your map with sv_cheats 1
  4. Join a team
  5. Disable any fog with fog_override 1
  6. Switch to the overhead view with cl_leveloverview X, where X is the scale factor you wish to use
  7. Turn on the 1024 marker by using cl_leveloverviewmarker 1024, to place a red marker on the right.
  8. Walk around (use noclip or change the scale factor if needs be) until the entire map is on the screen and left of the red marker
  9. Hide the game interface with cl_drawhud 0
  10. Take your screenshot, ideally in TGA format
  11. Note down the most recent position information displayed in the console
  12. Resize your screenshot from 1280x1024 to 1024x1024 using a photo editor of your choice.
  13. Create a VTF from your screenshot (see Creating a Material)
    • Due to the way in which mini-maps are displayed, transparency is generally something to avoid.
    • You can find a generic background image for your mini-map on the Day of Defeat forums. [1]
  14. Create a VMT for your new texture (see below for code)
    • Do not include the .bsp extension in $basetexture when creating the VMT
    • Ensure both files have the same name as your map, again without the .bsp extension
  15. Place both the VTF and VMT in the dod/materials/overviews/ folder
  16. Create an overview file in dod/resource/overviews (see below for code)
    • The file should be called mapname.txt
  17. Load the map and ensure that the overview is working

You may wish to use BSPZIP to embed the files you created in your BSP.

VMT code

"UnlitGeneric"
{
	"$basetexture" "overviews/mapname"
	"$vertexcolor" "1"
	"$vertexalpha" "1"
	"$no_fullbright" "1"
	"$ignorez" "1"
}

Do not include the .bsp extension in $basetexture!

Overview definition code

"mapname"
{
	"material" "overviews/mapname"
	"pos_x" "Your position data"
	"pos_y" "Your position data"
	"scale" "Your scale"
	"rotate" "0"
	"zoom" "1"
}
  • Do not include the .bsp extension for mapname!
  • Fill in pos_x, pos_y, and scale from the console message you noted down.

My overview is missing bits of my map!

The overview tool attempts to intelligently remove portions of the map that are not wanted on an overview: roofs, inaccessible areas, and so on. However, it is not perfect.

Required: how to get round these issues

Sometimes it also depends on what roof is your character on, before cl_leveloverview X command. Try to do various screens, by moving the character on different roofs before using cl_leveloverview X, then patch them all for better result.
