Now if I can just get the buoyancy working can't bring the density down lower than 100.

Strange, it is called "mass" in my RF5, but if it works it's ok

Increase the "impulse" in the fluid particle interactions and reduce the density/mass for better floating.

Okay, cool.

Running into another problem. At a certain point in my simulation, the ice cubes explode out of the glass. Not sure what's going on. I now have the cubes dropping into the glass at the beginning. And bounce is very low.

Any ideas?

Also, is it the particle force that I have to alter to get better floating? And how much should I increase by would 300 be too much?

I do not think there is any way to control the impulse strength within RF 5.

Impulse can be turned on and off, but the particle force is responsible for buoyancy. 300 is too much, I would rather start with something like 3, but these settings also depend on the size and proportions inside your scene.

Christian, what density would you use for ice? I have tried 1.00-97.00 and the ice cubes blast out of the glass.

Why do my ice cubes keep exploding out of the glass? This is driving me nuts. I'm trying everything here.

There are always many parameters influencing each other. Maybe you can upload the scene, so we can see the entire picture ?

I will upload a video soon of my problem. As for the cubes and the @mass attribute, I have found that if you use an in realflow cube, you get the attribute, but when I import a multibody, it's gone. Is there a way that I can import my ice cube models and be able to use the @mass attribute? I need it. If I try to just import it regular, my already imported geo will be deleted.
