Help  I want to float an object

Set the rest density of the fluid blueprint such that it is higher/lower than the density (mass per volume unit) of the rigidbodies that must float on it. If the density of the rigidbody is higher than the fluid’s, it will sink. If it’s approximately equal, it will float in place. If it’s lower, it will rise to the surface. Check the MultiphaseBuoyancy sample scene for an example of fluids/rigidbodies of different densities.

Note this is how buoyancy works in real life too. Let me know if you need any help!
I tried various things while comparing with the sample scene.

Probably the cause is not the buoyancy setting, but the Resolution is too small and rough, and the object is not pressed well.
The test object was a 1m sphere. I think the balance between the roughness of the Resolution and the size of the object was too bad.

I think it will be good if I adjust the balance.

By the way, as I asked earlier, if you have any good criteria for specifying the Mass of Blueprint and the Mass of Object, please give me some advice.
