So I found an interesting mod called PIP Optic Overhaul, it was originally for A18, then updated to A19 by another, and I'm attempting to update it to A20 for my own personal use.
The mod adds Picture in Picture optics for the 2x, 4x and 8x scopes.
Now a days, weapons are modelled with attachments, and the XML would set visible attachments when required. This system seems to conflict with me trying to add custom attachments to existing weapons and offsetting the scope offset. the exception to this is the Tactical Assault Rifle, which does not have an internal attachment for the 2x Scope.
So far, I have the new 2x Scope prefab loading into the game just fine. For the Tactical Assault Rifle, I am able to use the "ScopeOffset" override property for it just fine. It moves the scope around as expected. All the other guns I've tried to use the "ScopeOffset" property with seem to completely ignore it, some weapons having the scope model float, or staying at a default position of 0,0,0.
Note: I do not intend to publish this mod, however, any help I get, I'll pass on to the original mod authors.
