Assuming they're MP9&10 weapons, you need to copy the textures from the FPS Creator gamecore\guns\$ area of the gun you want and copy them into the directory in the built game's. Errant has mentioned this in the text files but it took me a while to find out too

1.IMPORTANT NOTICE ABOUT MULTIPLE TEXTURES!
After building your game, you MUST manually copy the following textures to the
files\gamecore\guns\model pack 9\1911
directory of your BUILT game or else the weapon will not display properly!
1911Rvweap_D.dds
ammo_D.dds
Hand_D.jpg
If you fail to do this, some parts of the weapon and the hands will not render. Also, enemy weapons will appear white."

Sorry all for my furious departure a while ago (well, almost 8 months xD) after deep thought I have decided to return.
I apologise to those I offended.
