Hello. I've been trying to create a scene where some meatballs float inside a soup. Looking around I saw some examples where raising the feedback scale on the flip solver makes the fluid and the rbd interact naturally, BUT. The results I get are weird at least. Raising the feedback scale appears to create some kind of force on the fluid surface but after a while the rbds drop to the bottom where they seem to be moved around by the fluid but their weight is unaffected -as displayed in the extreme example I upload-. I am obviously missing something but cannot figure it out. Any help would be greatly appreciated.

Figured it out. The problem was with the packed primitives. Thank you.
