Help I want to float an object

[moyashiking]

Resolution has little to no impact of buoyancy (how much an object floats). Density does.

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!

Thank you for your reply!

I saw MultiphaseFluidBuoyancy
I have a questions.

Looking at the Sphere and Cube Mass, it's heavier than the Bluprint Mass.
Isn't these just values to compare?
Please tell me the correct interpretation method.

Dense 2 (BlueWater)
    Rest Density 1000
    Particle mass (kg):
    2D:10
    3D;1

Light 2 (PinkWater)
    Rest Density 300
    Particle mass (kg):
    2D:3
    3D;0.3

Sphere
    Mass 50

Cube (2)
    Mass 20


By the way, I have something to worry about.
The object with the Obi Component was outside the Obi Solver hierarchy.
Is this okay?

I'm not good at English, so I use Google Translate.
I'm sorry if the meaning of the sentence is esoteric.
