"Set Mass Override in Kg" node doesn't affect child static meshes when root static mesh has physics enabled. The work around this is surprisingly simple; you put a scene component attached to the root mesh and attach the child meshes to the scene component. There was another semi work around way of turning the root mesh physics off and then changing the child meshes mass settings but sometimes this doesn’t always work so I stuck with the scene component trick.
