Shotgun Spread Fix addon

So, does this actually work with vanilla Doom 3 BFG? I've tried putting the def file where I think it should go and adding the line to the launch options on Steam, but it doesn't seem to do anything.

i downloaded this and all the screens ingame that are supposed to play videos are blank.

EDIT: also this doesnt work.

I'm not even going to look at this mod because
1) butt-ton of other mods also include fixes for the shotgun spread
ii) it's really a matter of preference (default spread is "22" but some like a value around 10-12 for half as much spread while others prefer lower numbers like 6 or 2 for distance and laser-focus though they tend to make the shotgun very OP) Plus default projectiles is in the teens I think but standard buckshot only has 9 balls per round, so both the number of projectiles and spread greatly affect the effective distance and also effective damage of the weapon, before even changing the damage value itself.
C) this mod most probably breaks other mods, or at the very least undoes any other customization to the shotgun that a mod may use.

Just edit the "spread" value in weapon_shotgun.def (you can also edit the number of projectiles and damage values in the same file). Player.def and ammo.def also contain useful things to change but you don't want to overwrite the whole file because it will most likely break something else.

This mod is kinda... redundant at best
