I was looking for a plugin that makes all characters the same height but couldn't find one so I (tried) to do it myself. This was a very quick adjustment I just changed the height values of all vanilla races, vampire races included, that I could find in CK to 1.0000. I haven't touched CK in years and I forgot how to check for conflicts but its just height adjustment it doesn't even have prerequisites, just skyrim, it shouldn't be a problem hopefully.

New version includes changes to snow elf race. Requires all 3 DLCs, at this point who plays Skyrim without those anyway.

I did not test this extensively, I just walked up my imperial to an altmer to check and called it a day, by default altmers are much taller than most races.

I found an Astridrace and changed that too, Astrid is nord but almost as tall as altmer, but I haven't checked in-game if the change took effect (Edit: that was actually her burnt character model). Something I missed is Cicero I forgot that he has always been shorter but I think his character scale is somewhere else because I'm sure I did not find a specific race like Astrid's.

Hopefully it doesn't break anything, if it does I apologize. Also if anyone with more experience would care to look into this see if anything is off, that'd be great. Would be even greater if they made a better version of this that wasn't pieced together by an amateur who struggled to remember how CK works. So far it works fine in my game though.

You can do whatever you want with this file it took me 10mins to make it.
