Can i add RigidBody to the child object?

If I add a RigidBody to the child object, can it affect the parent?
I would like a component that is in the child to have a greater mass than the parent Object.
Is it possible to do this? I already tried and it didn’t work

Thanks!

Hi @alexlukanga

You can use Fixed Joint for this. But if you only want affect mass of parent, much more efficient would be just adding its mass to parents.
