Hello

I would like to create a Fluid-RBD interaction. But as you can see in the image below, the fluid pushes the rigid body so strongly.

I need the rigid body to be a little bit heavy and to float on the fluid, based on its mass attribute.

(Decreasing the "Feedback Scale", didn't help).



Thanks for helping.

you need to make sure your Rigidbody Solver is connected before Flip Solver into the merge, then even Bullet objects will get Volume collision data to interact with FLIP and respect Density and Feedback Scale

Or you can try RBD object/Solver (still will need to be connected before flip)


alternatively for smaller scale you can try Vellum Solver which allows for nice fluid and rbd coupling even though it's not true rbd's, but depends on usecase
