[LE] Female Head NIF Issue?

[Gorgopis]

The vanilla female head nif has a left eye-opening bigger than the right eye-opening.

 

We would like to "adjust" the vanilla nif to have the eye-openings match in size.

 

This would be our first time modifying nif's, likely with a 3D graphics app?

 

But maybe there's a simpler way editing the nif directly?

 

Any tips?

 

Thanks.
