Replace Ped To Addon

Hi there,
I am trying to take a replace ped and turn it into an addon ped, I have the meta file already, and all the files in my stream folder, however, I still seem to crash when I go to spawn the ped in-game. The ped originally replaced a_c_deer, I wound up naming the ped a_c_bear and renamed all the files accordingly and created my peds.meta file correctly but I still crashed. I attempted to create an a_c_bear.ymt.pso.xml and then import it via CodeWalker and tried to use the resulting a_c_bear.ymt file but still no cigar.

I’ve scoured the internet and found some broken ymt editors so they were no help.

Any ideas?
