Anyone that may be experiencing bad textures can report them here. Please try to find the offending texture by getting it's filename or by taking a screenshot.
Also, open the console (~) and then click on the offending item. A FormID should pop up, so write that down. If the first two numbers are not 00, then also let us know the plugin that is in that load order spot.
This is mostly going to apply to users who have gone through the texture optimization process. It is still new to FNV and there are going to bad textures found, so report them and we can add those textures the ddsopt.ini and tell you how to fix it in game.
