Fallout 4

  • For new ammo types to work with the True Damage system, all you need to do is add damage to the Ammo record.
  • Before making a new patch, check there isn't one already in the True Damage Patch Repository. If there isn't a patch, you can request one on the posts tab.
  • If you'd rather make a patch yourself, read on.

Important
  • You should only patch ammo types that use bullets. You should not normally need to patch grenades, rockets or energy weapon ammo types.
  • In some cases, it may be necessary to completely exclude a weapon from TD. See Force Excluding Or Including Individual Weapons

The Math
  • The formula for how damage is calculated is as follows:
  • (Weapon damage + ammo damage) / 10 * WeaponType buff.
  • For example, if your weapon does 50 damage and its ammo does 400 damage, the base figure will be (50 + 400) / 10 = 45.
  • This number is then multiplied by any appropriate WeaponType damage buffs.
  • It is therefore necessary to multiply your desired in-game ammo damage by 10 when entering it onto the ammo form.

Instructions
  • 1. Open the mod that needs patching in FO4Edit.
  • 2. Expand the Ammunition tab and select the ammo you want to patch.
  • 3. Right click and choose Copy as override into...
  • 4. Select <newfile>.esp with the ESL flag only. Name your patch starting with "TD - " then the mod name. E.g. "TD - 9x39 Project"
  • 5. Double click your new patch in the left hand pane and find the copied ammunition record.
  • 6. Scroll down to DNAM - DNAM and find Damage. It will normally be 0.
  • 7. Double click the value and enter what you want the damage to be in game, multiplied by 10.
  • E.g. if you want the ammo to do 35 damage in game, enter 350.
  • When deciding damage values, choose something comparable to the values already used in True Damage to maintain balance.
  • 8. Close FO4Edit and save the patch. If you're using MO2, the patch will be located in your Overwrite folder at the very bottom of your mod list (left pane).

    Trying to patch a SKS type 56 mod, but it doesn't have a tab in FO4 edit for the ammunition, any tips?

      Are you sure it doesn’t use a vanilla ammo type?

    I'm trying to patch weapons, but I'd like to understand how to accurately calculate their dmg. Weapon damage okay, but what about ammo damage? Where can I find it?

      Probably easiest to look at the values on the vanilla ammos and decide based on that
