Wish there was another way around this, but CloudFish is right. You have to have the same codings in order for other people to see the correct markings. Since I have multiple markings packs, I store the files that each different one contains, then if I go into an rp with that specific markings pack, I just replace the files. It's a hassle and I wish FH wouldn't be so 'bothersome' in this sort of thing. I don't know if it is possible for FeralHeart to make a coding system work to where you can have as many markings packs as you want and still see the accurate markings on other people, but if they can, they SHOULD XD
