I'll move this over to the "Game Opinions & Ideas" board for you, as I believe the subject of your topic is regarding your own feedback/opinion of Feral Heart.^^
I'm glad to hear that you've generally enjoyed the game, based on your experience thus far. The situation with viewing others' markings is a bit of a tricky one, as there are different marking packs that people use. Because of this, you need to download the specific marking pack to see the kind of markings you want to view. As the users above mentioned, you can download the most popular markings pack to get rid of those white, textureless blobs.
Thank you for your feedback!
