Hey guy's I was just wondering if how you go about 3d modeling power armor for fallout 4 I searched it up and found out your supposed to use topology, shrink wrap, and snapping tools on a vanilla model in blender but I just don't know how I would go about that and as far as I know there is no tutorial about it. at least none that I know of
