Hi, I'm simulating a glass with red wine shattering on the ground. The first question is that when I pre fracture the glass with voronoi it only keeps the liquid inside if I use rbd glue object in dopnetwork however if i use rbdfractured the liquid starts to penetrate the glass as well as breaking apart when falling. The effect of the pieces breaking works better with the rbdfractured. Is there a simple way of keeping these pieces glue and able to contain the fluid inside until it shatters on the ground? I'm also wondering if i could render the glass separate from the liquid and what would be the set up for the mantra ? or do I need to have them both ready to render together in order to get all the reflections from each other?
