This plugin assigns varying heights to most of the NPCs by altering the scale of their in game reference markers. It was done manually, so in general men are taller than women, and I tried to fit the height to the character, so when Ymir says, "You're so... small" it actually makes some sense.

Assuming that the base scale of 1 corresponds to the real world average male height of 5'10", Jotun is now about 6'8", and Ymir is about 6'3". Carolina Red is 5'1" (this plugin does not otherwise change any character's appearance, so the screenshot isn't 100% accurate). Bittercup and Charon were left at their original scales, but other than that, just about every named character I could think of (and find) has been changed.


Installation:

To install, just unzip the .esp to your Data directory, and add it to your list of plugins.


Issues:
___________________________________________________________________
* Changing the scale creates some clipping problems, particularly with sitting NPCs, but I still think it's preferable to a totally uniform height.

* I'm pretty sure run speed and melee attack range both scale with, um, scale, so gameplay may be effected slightly.

* Some of the characters have multiple reference markers. I found two for Colonel Autumn, but any others were missed. Off the top of my head, Moira, as a ghoul, is probably half a foot taller than Moira as a human, but that should be changed in the next release.
