    could someone help me out on this? ive been a modder for various games for YEARS but i have predominantly done graphics work. so i missed out on learning all these tricks. if someone could point me in the right direction of learning the basics of using a hex editor to work fallout 3(which i believe is the only option for things like adjusting weapon damage) i would be most apreciative.

    I second this request. I'd like to make some modifications to Fallout 3, but I'm not very familiar with hex. I think know what to do in order to change a weapons's name... but that's about it.

    Any help would be appreciated. Like maybe a tutorial in layman's terms on what the different values are, etc.

    First off, you need a tool. The best one around so far is Timeslip's FOMM. I won't go into how to create a new plugin and cut straight to the chase. The entries you're looking for are DATA and DNAM.

    DATA looks like this:
    F4 01 00 00 90 01 00 00 00 E0 40 0B 00 18
    The numbers you're interested in are the 90 (weapon health), 0B (damage), and 18 (magazine capacity.

    These numbers are in hex. If you don't know hex, don't sweat it. Just open up your Windows calculator, punch in the number you want and click the 'hex' button and it will show you what that number is in hex.

    Mucking about with the DNAM is more tricky, but this is where you can tweak real-time accuracy, rate of fire, zoom, and a whole host of other fun stuff. I would have to write a proper tutorial to explain what was what in there and most of us are still figuring it out.

    Hope this helps a little bit.

    Yeah, that helps alot. Those are the main values I was looking to change. I do have FOMM and I'm not new to game modding, just new to FO3 modding. :)

    I somehow missed this thread while looking through the forums. Thanks!

    This is a good thread. I was asking for some advice/help in my own thread about some of those things. I guess I’ll just have to do everything myself. So thx for the info.

    Still. Does anyone know a way to change models? I have seen this mod that changes the looks of BOS Power Armors to the T-51b with a different skin.

    But I only want to give the T-51b model to a few selected high ranked NPC’s.

    Can anyone help me with this?

    Oh ye I also wanted to change some item descriptions. I have never ever created a Fallout mod… actually I have never created a mod at all. But I’m very determined to make a mod/mod pack that would make Fallout 3 more Falloutish. I wanna start with a lot of small stuff like adding a lot of different textures and changes in item statistics and when I’m done with all that I’d love to implement my idea of a universal “Super Repair Kit” (kinda reminds you of that Super Tool Box doesn’t it?) that would fix up one of your items.
