Alright so I have no idea when or how, but it seems like I've borked the meshes for the FO3 weapons - when I first installed TTW they had their sighting nodes so I could actually use the sights, but somewhere along the way while installing various mods it appears that they've gone missing...as a result they're now using the meshes inside the bsas which didn't include sighting nodes since they were FO3 weapons.
I've also tried snooping around in the TTW installer but can't seem to find the sighted meshes either...thanks in advance!
Using 2.9.4b although I doubt that'll be useful for this kind of problem
EDIT: Well it seems like the patched Fallout3 - meshes.bsa actually has sighting nodes on all the guns...now to find a way to make the files in that bsa the winrar on the bsa load list aww yiss, forced fallout3 - meshes.bsa to load 2nd last by editing Fallout.ini and FalloutPrefs.ini and it works! It frigging works! Last bsa was my merged patch where I consolidated a whole bunch of mods into one plugin, as well as any loose textures and meshes to cut down on the total number of loose files.
