If you want the right material sound for the map DogWar (as i reccomend) copy everything below and paste it in your materials.txt document at the bottom of all the other info that is already there. If unsure of what you do, make a backup of the original file and keep it somewhere safe, like under you mattress ;) The materials.txt document is found in your dod/sound folder. spine //------------------------------------------------------------ // dod_dogwar.wad //------------------------------------------------------------ W floor3 W planks1 W planks2 W wood1 W wood2 D rubble1 D rubble2 D rubble3 L road1 L gravel T floor1 T floor2 B cobble1 B road2 B road3
