Ok to be able to mod battlefield 1942 demo you have to create another copy of the map as you can not change the origional file, You name it this : Real level hellendorn modded level hellendoorn_001. You can now mod that. I have a problem, i use RFA explorer and this is the problems i came across, i made a video:
http://www.youtube.com/watch?v=pZPMiDd2m6wI got past the error problem by deleting the lightmaps then that worked, then a different error came with the textures so i deleted that. Then it worked there, then it said file access denied. I am stuck now, what do i do. Is there a different approach? I am a beginner to no detailed answeres please. Any videos would be great but i dont mind.
Thanks a lot
