I just extracted a workshop addon for the N7 Dropship from ME3. I edited the textures then imported them into VTFedit and saved them over the original files. But when I spawn the ship in game, it uses the old texture. I'm a noob, so I'm guessing I missed a step here.
Here is the addon I ripped: http://steamcommunity.com/sharedfiles/f ... =107414835
Changed red textures to yellow and altered the lettering on the ship. Still shows up red
