Masoud Posted September 12, 2022 Share Posted September 12, 2022 (edited) Hi guys, I have two RBD objects, floating on FLIP-fluid. I set the Density (mass) to 400 (lower than the fluid mass). When two objects are of the same amount of mass, they have to react in the same way, right? I mean in this case, they have to stay on the surface. The problem is the bigger object stays on the surface, but the smaller one sinks into the fluid: - How can I fix it? - How can I set the density(mass) in the SOP level (as an RBD source)? Thanks for helping. Floating RBDs.hip Edited September 12, 2022 by Masoud Quote Link to comment Share on other sites More sharing options...
