So I was playing around and got a third person view with a cube. So now I have a playable cube. I want to apply a material using the defaults(like metal) onto the cube in components(in the blueprint editor) for the third person view. So then I could play as a metallic cube(or whatever material I put on it). So how would I go about doing this.Don’t ask why, just very curious 
Just add the material in the static/skeletal mesh editor to your cube 
-> double click onto the mesh - select the material in the content browser - add it to the material slot in the static mesh editor
