the game has tools to allow you to do it yourself, I think?
the game has skin options for anthro models ONLY like changing color or add extra hair/ fur
as for MAKING the skin trust me i tried too complicated and annoying like downloading unity & belnder BUT to use unity tool and make a skin you gotta have a human model to work as skin but all skins in blenderkit ether with money or colorless grey not to mention set scale right
BUT if you think you can make a skin model, feel free to share it here
