Does such a thing exist? I'm tired off seeing my character speed walk in the air like i've just typed in TCL in the console menu.

Any help would be greatly appreciated!

Well.. that's disappointing.

How hard would it be do make something like this? I have little to no animation experience. I have quite a bit of 3d/nif handling experience, though.

It's hard-coded into the game engine. Maybe OpenMW will allow a change; if it ever exists.
