Make your way to your game folder and locate your maps "MIS" file. Open the MIS file in Notepad. It will look like the image below.
Change the value for the "Terrain_Color", Then open the file tab and click save. Close Notepad.
Open your map with the Mission Editor (MED) and save your map. Thats it!!!

If your map is a jungle terrain you don't have to do anything, the default camo is jungle.

For Jungle Camo the Terrain Color is set to 0 (Zero)

For Desert Camo the Terrain Color is set to 1 (One)

For Snow Camo the Terrain Color is set to 2 (Two)





We removed our Camo Mission Editor, that is why we are changing Camo manually.

Just a little added clarity for those who are editing .mis files: After you are done editing the .mis file you need to click "save as" instead of "save" in the file tab and put .mis after your file name. For example, say you have edited a .mis file named "92 Where Am I", your "save as" file name would be "92 Where Am I.mis". Otherwise you would just be creating a standard text document. Also, if you edit the .mis file with your actual map opened in the editor no changes will be saved, close the editor first then make changes. Hope this helps.
