This is a script for FNVEdit that allows to create a patch plugin and modify weight of all playable ammunition in hardcore mode (and optionally grenades weight). Patch is dynamic, it is created for the current load order and supports absolutely any plugins.

Installation

1. Get the latest FNVEdit
2. Unpack script into "Edit Scripts" folder of FNVEdit
3. Start FNVEdit and load all plugins, make sure to start it from within MO if you use it
4. Select plugins to patch in the left pane using Shift or Ctrl click, Ctrl+A to select all when focus is there
5. Right click on selection, then "Apply Script" in popup menu
6. Select script "FNV - Hardcode weightless ammo patch" from dropdown menu and click OK
7. Give new name for a patch plugin when asked and confirm adding required master files
8. Close FNVEdit and save newly created plugin when finished
9. Keep it at the end of load order after all patched files and activate in mod manager

Remember that you need to delete patch and recreate it any time you modify your load order, especially when adding/removing/reordering plugins that change ammunition properties. Failing to do so will probably result in crash to desktop when starting game if patch plugin depends on master file that has been removed from load order.

Ammunition weight is controlled by fAmmoWeight variable at the top of the script, default value is 0.001 (tweaked for my taste). You can set it to 0 for truly weightless ammunition if needed.

Grenades weight is controlled by fGrenadeWeight variable at the top of the script, default value is 0.1, set to any negative value to skip patching grenades.

Wrye Bash/Flash users: WB marks this patch as mergeable and asks to deactivate when building bashed patch, but for me it doesn't merge it at all. So don't deactivate it or load after the bashed patch.


Uninstallation

Just delete patch plugin, it doesn't use any game scripting and safe to remove any moment during gameplay.
