this skin is compatible with the addonpeds mod,make sure to check the “is streamed” box during the config
if you don’t use the addonpeds mod you can replace any character located in
x64e.rpf/models/cdimages/streamed peds ig.rpf
just rename both christie files (the .ymt and the .yft) and the folder to the character you want to replace.
