I know this has been addressed a thousand times, but whenever I try to make a new hat, it ends up sideways. I'm not using a new mesh, but one in the game, I just want to put a new texture on it. When I do though, and I hit "update facegen model availability", all the hats in the game end up sideways. I have no idea what to do at this point (I have no experience adding new models, but am fairly familiar with GECK/TES Construction Set). Any help would be appreciated.

I have had this issue too. No idea what could be causing it. All I did was create a duplicate of a hat just to add some new stats and it pulled this on me.
