I had a really frustrating problem when I was just starting out at learning how to add pets. And what some forgot to mention in the guides, created an error when trying to view the pet in pet bag, evolve oven and composing.
So I'll clear it up for everyone. When your entering data into 3DSimpleRole.ini you need to put it in order for it to work. So that means if your pet's ID is 1071250 and its SimpleRole being 'Pet1250' then you must put the entry in after 'Pet1240'.
I'm not sure if this solution was posted or anything, I've just heard of a few people having the problem recently and you would do well to remember this in future. Good luck!
