How to flip a mesh?

[John Jr.]

Hi, guys. I need some help.
There's any way to flip horizontally a mesh piece? I just want to invert the hair part on some VX wigs, but I have no idea how I can do this. May anyone help?
Thanks in advance.

f you're still trying to figure this out, in Blender there is a "mirror" to flip a mesh in any of the 3 axis that would probably do whst you want

Yes, you can do it with nifskope. Select the piece, transform/edit and you will be able to rotate the piece.
