I've run into a problem with the preview window for the Creation Kit. Recently, everything started showing up with nothing but dim orange and blue lights illuminating it.
I don't know what caused this, and I've been stumped for a solution. As far as I can tell, these are the "warm" and "cold" lights in the preview window, but modifying them doesn't restore the brightness of the default lighting. Deleting the INI files - for anything and everything related to Fallout 4 - has not resolved the issue. I know I've had this issue in the past, and I still don't know what solved it. This makes it very difficult to assess the details of a mesh, so I'd really like to find a reliable solution for this.
