Enabling collision with Niagara 3D liquid

Looking at UE5 content examples the 5.2 Pool show a skeletal mesh colliding with the liquid.
Added two movable mesh the cubes, enabling their physics sim these are moved from the skeleton, but are not influencing in any way the liquid.

Wanted to ask how to enable their interaction with the fluid.

I can’t check right now, but I think you just have to give them a collision tag. Check the skeletal mesh that is colliding for tags, then copy-paste that to the cubes.

Hi davide445,
The character is influencing the liquid through HeroTPP_Physics2. You could either add your box there or give the actor the actor-tag (Actor-> Advanced-> Tags) ‘collider’, as the fluid in this example can support both.


Using “collider” tag works, thanks.
