Edit fov weapon far cry 4 plz

First of all, convert patch_unpack\generated\worlds\fcc_main\entitylibrary.fcb, then search for WeaponProperties where you will find all the weapon properties for all the weapons along with their ark files.

Now, for example, if you want edit STG-90, here is the section you need to go for:

<object name="Archetype">
<field hash="1BA57278" type="UInt64">7598204997445</field>
<field hash="B435B769" type="String">entityarchetypeslibrary\7598204997445.ark.fcb</field>
<field hash="2D90D933" type="Hash64">B520B6EC10617C70</field>
<field name="Name" type="String">weaponproperties:fc3/stg-90</field>
<field hash="15193718" type="String">WeaponProperties</field>
</object>
It tells you what ark file you should look at. In this case, 7598204997445.ark.fcb, which can be located after you unpack fcc_main.fat/dat.

The next step is you usual routine for FC3, you should know what to do.
