TyFlow Smoothie

This setup does not require any liquid simulations and it's more suitable for still frames. Also this is an example of floating objects on a liquid surface without a real liquid sim - buoyancy force is faked with a couple counteracting gravity forces (up/down) and a constant check "is object submerged" (SurfaceTest/Raycast). This fake can't replace a real liquid sim but sometimes it's good enough. Liquid surface is done with TyFlow VDBs and it's quite slow because it's recalculated every frame. If you need a still frame - just set desired start frame in the VDB Birth op.
