Every face mod that relies on NL Facial Animation has to have support added by hand. It is very tedious and time consuming. I've already got two on the to do list with no time frame, so your best bet is to do it yourself.

Look in the ModSupport folder for the structure that needs to be followed. You basically just need to pick the male or female graphic you want non-binary to use and copy it into a folder called Enby. If there's a face you want to use that is exclusive to male or female, you'll have to make your own def with 3 as the gender. Then add the folder to LoadFolders.xml.

after some trial and error i believe i've gotten it to work!
thank you so much for your help, now my pawns are perfect
