According to https://wiki.nexusmods.com/index.php/Creating_an_armour_for_Fallout_4._Part1, body / armor meshes no longer need 2 types of meshes to blend between to create a fat/skinny body. In other words, the engine itself somehow generates a fat or skinny or muscled body automatically! On the technical side, does anyone know how this is done? I cannot find any information on the topic. Thank you so much! Josh
