Does anyone know where I could get the texture for the aa12 combat shotgun that comes with Fook2 (I think). There are only two times in the game so far where it appears (a slaver and dashwood) but that big red ! is annoying.

The weapon mod kits mod has an optional AA12 combat shotgun replacer. I don't use FOOK2, so this is just an educate guess.

Okay, I'm a little farther into the game and now I'm missing the texture for the p94 winchester plasma rifle. The funny thing is, if my character is holding it it shows up, but when someone else is holding it I get the ! Can I copy the texture from somewhere to somewhere else to fix this?

The big red exclamation mark indicates a missing mesh, rather than a missing texture.

If you've installed the WMK AA-12 Combat Shotgun replacer (FOOK2 version) esp that comes with the WMK-FOOK2 http://www.fallout3nexus.com/downloads/file.php?id=4968 patch, make sure you've also installed the meshes and textures for it; available in the original WMK AA-12 Combat Shotgun replacer file on the http://www.fallout3nexus.com/downloads/file.php?id=3388.

The P94 is a known FOOK issue - check the http://www.fookunity.com/forum/showthread.php?t=2576. That being said, all of those fixes are in FOOK2 1.1 Open Beta, which comes out in the next 24 hours!
