After you give enogh meat and talk enough with Camille, you get new quest for Camille. She is say you this: Come back evening, i wating for you. You talk with her evening and Camille say you: My sister Velvet eat all time bullshits, here this package, give her pls.
to do that event you have to leave the camp at 3:00 pm (teleport xd) then nyotalia mission will appear on its own
So, in the previous version patches for 0.8.4, there was a quest added for Camilla where you have to deliver something to Velvet. (Can't remember what it was). Once complete, between 17:00 and 19:00, Velvet will shower at an outcropped edge near the waterfall (the area at the beginning where you got the horse). If you approach the area from the pathway, a cutscene will trigger. You then have the option of watching her shower or revealing yourself for a set of two h-scenes.
