As far as the map... in the resource.assets file you will find two map entries. One is the game map. With the plug-in button pressed at the bottom. click on the map name and you should see the map image in the right hand side. if it isn't the map your looking for click on the other map entry. Right click on the name to export or import the map into dds format. Then save as after importing. Keep the original map.dds file. you may need to re-import the original if something goes wrong. when you are viewing the map, not the info above the image in the info bar. it will tell you the format of the image and if mipmaps are used.
