access to BufferGeometry in SupThreeScene.getObjectByName("name").children to manipulate verticles

[sunnydrake]

Hello, i need to manipulate verticles of Mesh to do this is need to get type mesh from children array of Object3D by SupThreeScene.getObjectByName("name").children[mesh_object_position] + bump SupThreeScene.getObjectByName("name").children[mesh_object_position].geometry.attributes.position.version (or just call buffer_geometry.attributes.position.needsUpdate = true; buffer_geometry.attributes.color.needsUpdate = true;)
unfortunetly SupThreeScene.getObjectByName("name").children[] only returns Type Object3D :(
