Problem with saddle

Hello,

I want to made a saddle for a dino that dont have one. i have an own mash but i cant use it because i dont know how.
I copyed the Ankylo Saddle but i dont find i way to add my mash … if i use it the dino uses the Ankylo saddle instat of my new one …

Anyone can help me ?

The relevant setting in the PrimalItemArmor file are here under “Actor Attachment Attachment Infos”:

Thanks so much !
What kind of sorcery ist this i only find the mash if i use “Actor Attachment Attachment Infos” … was searching for hours…

Is there any option that shows you every hidden tab in a pluprint like this one too ?
