Hi, I recently used the Fallout 3 Archive Tool to unpack the .bsa files for New Vegas. I haven't modded anything but now I'm seeing the characters heads/faces clipping through their hair (I did not have this problem until I unpacked the files). Anyone have an idea on how to fix this?

Yeah... don't unpack them directly into your Data folder, but into an external directory. Only override meshes/textures/what have you should be in the Data folder outside the BSAs.

Well, lesson learned. Thanks for the advice.

Wow, I dodged the bullet on this one. I didn't know this would be a problem but I extracted 'em to an external folder anyway (C:\Games\Game Resources\Fallout New Vegas)
