RFA extractor -do not use this for textures...use gmakerfa for textures... gmakerfa is on the easy texturing page..
open the rfa extractor and choose file and open then the path should be c:/program files/ea games/battlefield1942/mods/bf1942/archives/bf1942/levels now select the map you want to extract( the ones with NO numbers berlin.rfa now select the map and hit open now all the files will be listed in the extractor now select extract and then choose all files then local disc (c:) then hit ok now it will make its own folder in the c:/ c:/bf1942 when using the map editor this is where you will look for the heightmap now go edit your map
RFA Maker to use your own map name go to changing map name to get it correct or it will crash..
ok now your ready to pack it up and try it out ..so lets pack it up and see what happens- hit enter after each step any spaces in map name use _ for spaces now open the RFA maker enter the root directory to compress: c:/bf1942 enter the base .rfa path: bf1942 would you like to see a list of the .rfa directories that will be created y/n n enter the name of the new .rfa my_new_map.rfa use your map name here.. (dont forget to put .rfa after the name of the map or it won't work.) would you like to compress the .rfa? (very slow)y/n n map created with ??? entries now the new my_new_map.rfa file you just made will be in the folder that the rfamaker program is in now go find it and copy and paste it into your levels folder if you don't change the map name you have to delete the existing map and paste in the new one if so make a copy of the regular one and save it somewhere to use later its easy and the best if you change the map name first then all you need to do is paste it in the levels folder and go in and select your new map and play it..
