>>4919325Yup. Only vanilla. Technically, you can just add all meshes and textures needed to add any armor you want your character to wear, add the .esp into the creation kit without making it the active file and put it on your character, then make the .esp with your character and the armor. I'm fairly certain that should work, but I'm not experienced with the CK at all.
>>4919386No clue about any wall, sorry. But to place your follower in the Bannered Mare (which basically is the unofficial place, so that Guardly can pick them up for pictures.) is to go to the Cell list, pick WhiterunTheBanneredMare (Just go Whiterun and you'll see it fairly high up) and drop your NPC on the floor.
Just remember to put it at the edge of something, otherwise it'll spawn mid-air. I usually use the edge of a rug or a chair. If my jargled up words confuse you, have a video.
