Can anyone point me in the right direction in the PZ code on where to find the stat values for patch types. I am able to create a new fabric type and have it show in the UI, but I am struggling to find where the scratch, bite and bullet values for the original 3 patch types are (when added as padding to clothing), and where I can add values for a new patch type so that they are added to the clothing item when the new patch type is applied via padding.
