Sorry, but that is simply not true. I wouldn't have written that and taken the pictures to clarify the situation, if I hadn't tried it before. It's exactly like stated in the pictures. Perhaps the creator of the Monli Race simply overlooked the 1st person skeleton (and that it's used by all races) or he didn't intend to change the 1st person height or he simply didn't bother or ...
I can answer that, the skeleton in Monli folder defines amongst other things the height of your 1st person view (not 3rd person as you write).
With my question in one of the pictures, I just wanted to know, what's the difference between the skeleton files from the Monli Pack and Kashim's skeleton files, which he put up in his first post. He already answered it and said, that his skeleton also changes the size of weapons, so that the weapons aren't huge, when used with Monli characters.
I understand that perfectly fine, but it doesn't change the fact, that the skeleton files in the Monli folder only influence the 3rd person and the visible weapon size (as also stated by Kashim) of the Monli race and not the 1st person view. Maybe there are other (3rd person) things, too, which are affected. I don't know about such things. But the 1st person view is definitely not concerned by these skeleton files.
By having it in seperate Monli folder you can have normal skeleton for all other races, meaning you can have for example a Lydia with huge "tracks of land" (unless a UNP armor mod redefines them as the armor mods overwrite the default skeleton with what the armor was made for) and at the same time a slim and small avatar. When Monli is correctly installed there is no use for setscale command as the character automatically starts smaller.
Never had a problem with the height. The Monli Race has always been as small as it's supposed to be.
If your Monli character has the size of a Nord something is fishy in the state of Denmark. Hope this helps.
