Fastest way to create nwn 2 portrait with Tchos' HD UI

So i have noticed that nearly the correct size are the huge portraits from nwn 1.
For my rpg’s i have been using .
Fast way to create portraits, unfortunately when it comes to nwn 2 it creates portrait for nwn 2 in a size of 128x128 which is a lame resolution. A proper size is 256x400.
Thanks for the help,
